| *** larstobi has quit IRC | 00:00 | |
| jk0 | soren: go to router.soren.com/mode.htm | 00:01 |
| jk0 | there should be an option to switch from NAT to Bridge | 00:02 |
| fcarsten | soren: Might be called "RFC 1482" | 00:02 |
| fcarsten | 1483 that is | 00:02 |
| jk0 | (make sure you jot down your auth creds first :)) | 00:02 |
| soren | jk0: Uh. Yeah. | 00:02 |
| soren | jk0: How'd you know? | 00:02 |
| jk0 | know what? | 00:03 |
| jk0 | oh and make note of the VCI/VPI settings in case those need to be set explicitly in bridge mode (shouldn't) | 00:04 |
| masumotok | soren: sorry I send you merge request many times(since I found I forgot pep8 checking) | 00:04 |
| masumotok | vishy: sorry I send you merge request many times(since I found I forgot pep8 checking) | 00:04 |
| soren | jk0: How did you know about that mode.htm? | 00:05 |
| jk0 | soren: oh, google :) | 00:05 |
| soren | Ah. | 00:05 |
| Xenith | Note that if you switch your router to bridge mode, you won't be able to switch it back without resetting it. | 00:05 |
| jk0 | yeah, that's why jotting down those VCI/VPI settings is critical | 00:06 |
| jk0 | that should be all you need, other than auth | 00:06 |
| soren | This is looking like a project for a different day. | 00:06 |
| soren | :) | 00:06 |
| jk0 | or any static IP info if it's not DHCP | 00:06 |
| soren | masumotok: np | 00:06 |
| *** adiantum has quit IRC | 00:07 | |
| soren | vishy: Approved. | 00:07 |
| Xenith | Yea, I think your best bet for v6 right now without munging your network is the Sixxs ayiya tunnel. | 00:07 |
| jk0 | last I heard there were problems with the sixxxs signup page | 00:08 |
| Xenith | Dunno, I've never used them, of course :) | 00:08 |

| soren | vishy: Are you going to review https://code.launchpad.net/~nttdata/nova/live-migration/+merge/44940 ? | 00:17 |
| openstackhudson | Project nova build #402: SUCCESS in 1 min 25 sec: http://hudson.openstack.org/job/nova/402/ | 00:18 |
| openstackhudson | Tarmac: This modifies libvirt to use CoW images instead of raw images. This is much more efficient and allows us to use the snapshotting capabilities available for qcow2 images. It also changes local storage to be a separate drive instead of a separate partition. | 00:18 |
| openstackhudson | I'm proposing this branch for review to get feedback. I may have inadvertently broken a few things. Comments and possible issues: | 00:18 |
| openstackhudson | 1. I haven't tested the other hypervisors. I may have broken libvirt xen support and uml support with this patch. | 00:18 |
| openstackhudson | 2. Is it useful to have a use_cow_images param, or should it just be automatic for qemu/kvm and turned off for everything else. | 00:18 |
| openstackhudson | 3. create_image is a large annoying method. I tried to clean it up a bit, but it could probably use a bit more refactoring. | 00:18 |
| openstackhudson | 4. disk.py seems to be only used by the hypervisors, so perhaps it should move into virt dir. | 00:18 |
| openstackhudson | 5. disk.py/partition() is unused now. Should we leave it in or throw it away? | 00:18 |
| openstackhudson | Comments welcome | 00:18 |
| Xenith | What are cow images? | 00:22 |
| vishy | soren: just did, that took for ever | 00:22 |
| vishy | woah, cow merged, nice! | 00:22 |
| soren | vishy: Yup. | 00:22 |
| vishy | Xenith: CopyOnWrite | 00:22 |
| soren | vishy: I don't see your comments on the live-migration mp? | 00:23 |
| soren | vishy: I've read through that patch 3 times already. It gets harder each time to stay focused. | 00:24 |
| fcarsten | Xenith: http://en.wikipedia.org/wiki/Qcow | 00:25 |
| vishy | i just sent | 00:25 |
| vishy | t | 00:25 |
| vishy | h | 00:25 |
| vishy | soren: might take a minute to pop up. I made a ton of comments | 00:25 |
| soren | You e-mailed it? | 00:26 |
| vishy | soren: i wish i had time to review earlier, there are a lot of minor issues | 00:26 |
| soren | Oh, I see it now. | 00:26 |
| masumotok | vishy: I got your comments. thank you for reviewing! | 00:27 |
| vishy | i really wish lp had line by line reviews a la reitveld | 00:27 |
| vishy | msumotok: you're welcome. sorry it took so long, I've been super-busy | 00:27 |
| masumotok | vishy: I know. | 00:28 |
| vishy | masumotok: by the way, excellent work. Most of the issues my review are just for style and constincency | 00:29 |
| vishy | s/constincency/consistency | 00:29 |
| Xenith | So with cow images, one can do VPS-like functionality? | 00:30 |
| Xenith | Actually, I'm probably just fairly confused on the whole writing to the running image thing. | 00:30 |
| Xenith | Not sure if my understanding is at all correct :) | 00:30 |
| soren | vishy: Quoting the patch in the review seems the best approach to me. It's the most compatible with e-mail reviewing, too. | 00:31 |
| soren | vishy: The worst is when people refer to line numbers. They change every time someone pushes to the branch, so it's useless when looking back through the history. | 00:32 |
| vishy | soren: yeah, it is just painful for long reviews. Reitveld would show you diffs on one file at a time and show you comments inline | 00:32 |
| vishy | soren: it made it way easier | 00:32 |
| soren | vishy: Did it allow you to review stuff by e-mail? | 00:33 |
| soren | Otherwise, it's a fail :) | 00:33 |
| vishy | soren: yes | 00:34 |
| soren | So it'd extract your comments and show them in-line on the web? | 00:34 |
| soren | That sounds awesome. | 00:35 |
| fcarsten | Xenith: COW e.g. allows you to privision VM images very fast. You don't have to copy the complete image for every VM. You just create a "reference" to the one image and only keep track of changes (write operations) in a VM specific file | 00:35 |
| * soren desperately needs sleep | 00:36 | |
| fcarsten | Xenith: A COW image supports these "reference and keeping track of write changes". | 00:37 |
| Xenith | Ah. | 00:37 |
| * vishy thinks soren is a trooper | 00:38 | |
| *** dfg_ has quit IRC | 00:39 | |
| vishy | Xenith, fcarsten: + Qcow2 supports instance snapshotting and restore inside the image format | 00:39 |
| masumotok | vishy: thank you! I'm struggling to fix now.. | 00:39 |
| *** dirakx has quit IRC | 00:40 | |
| Xenith | Am I correct in my understanding that inside an instance, its basically a ramdisk, so any writes you make are lost? Ignoring the volume and object storage for the moment. | 00:43 |
| vishy | Xenith: no changes are saved on to disk | 00:43 |
| vishy | if your host crashes, some stuff may be buffered and not make it | 00:43 |
| vishy | but the instance on the host should get updates | 00:44 |
| fcarsten | vishy: you might want to add a comma ;-) : no, changes are saved to disk. | 00:44 |
| Xenith | Right. But changes made to the running instance are not saved if you restart the instance? | 00:44 |
| vishy | if you do a virsh destroy <id> and virsh create /path/to/instance/dir/libvirt.xml you will | 00:44 |
| vishy | have all of your changes | 00:45 |
| vishy | in fact reboot instances basically does that | 00:45 |
| sandywalsh | xtoddx, thx ... having a look | 00:45 |
| vishy | fcarsten: yes, there was supposed to be a comma there. Typing fast and typing well are orthogonal for me apparently. | 00:45 |
| vishy | Xenith: btw, the same is true for amazon as well, they just don't tell you. If you contact support i understand that they can recover crashed instances for you. The best use of cloud would be to not have to worry about recovery though. | 00:47 |
| vishy | Xenith: so most people act as if the instances are ephemeral | 00:47 |
| Xenith | Yea, just trying to think my way through this. I understand that generally you want to keep changing data on a volume or object storage or DB node | 00:48 |
| Xenith | Trying to think if nova can be used in a more VPS-like fashion. | 00:48 |
| vishy | Xenith: it can, in fact, the rackspace use-case is more vps | 00:49 |
| fcarsten | vishy, Xenith: This may not always be true. E.g. OpenNebula explicitly cleans (ie.e deletes) VM instance specific files (unless especially marked not to) | 00:49 |
| vishy | Xenith, fcarsten: yeah, eucalyptus was notorious for randomly deleting instance files | 00:50 |
| vishy | on host reboot and such | 00:50 |
| Xenith | Yea, we were originally looking at euca, but I kept pushing openstack :) | 00:50 |
| vishy | Xenith: \o/ | 00:51 |
| Xenith | vishy: One thing I'd love to do is replacing all our older hosting servers with VPSes. | 00:51 |
| Xenith | Because it gets harder to find replacement hardware for them :) | 00:51 |

| masumotok | vishy: are you there? I just want to ask you about your comment. | 02:48 |
| masumotok | vishy: in your comment, "is it really necessary to have a separate host table instead of adding host info to services table?" | 02:48 |
| masumotok | vishy: actually, just adding host info to services table is good. | 02:48 |
| masumotok | vishy: From other point of view, in nova.api.ec2.admin, there are some code "host_get" "host_get_all" | 02:49 |
| masumotok | vishy: those code are expected separate host table. | 02:49 |
| masumotok | vishy: so, I think if I just adding host info to services table, other people create host table and adding similar column. | 02:49 |
| masumotok | vishy: Therefore, it may be better to choose keeping separate host table, and create relationship Service -> Host. | 02:49 |
| masumotok | vishy: Or, if nova.api.ec2.admin is discussing phrase, I remove host table because we are not sure. | 02:49 |
| vishy | masumotok: that is fine with me | 02:49 |
| masumotok | OK, I keep separate host table. | 02:50 |
| masumotok | vishy: thanks! | 02:50 |
| vishy | masumotok: I don't see why we need a separate table yet, but we may at some point so I guess it is fine | 02:50 |

| openstackhudson | 2. run the sheepdog daemon on each hosts | 04:43 |
| openstackhudson | $ sheep /store_dir | 04:43 |
| openstackhudson | /store_dir is a directory to store sheepdog objects. The directory | 04:43 |
| openstackhudson | must be on the filesystem with an xattr support. | 04:43 |
| openstackhudson | 3. format the sheepdog storage | 04:43 |
| openstackhudson | $ collie cluster format --copies=3 | 04:43 |
| openstackhudson | 4. run nova-volume | 04:43 |
| openstackhudson | $ nova-volume --volume_driver=nova.volume.driver.SheepdogDriver | 04:43 |

| *** adiantum has quit IRC | 07:05 | |
| mtaylor | anticw: just push one up ... so : | 07:06 |

| *** ibarrera has joined #openstack | 07:07 | |
| anticw | yeah, just found that | 07:07 |
| anticw | that registers it as well? | 07:07 |
| mtaylor | anticw: and then go to it online, such as https://code.edge.launchpad.net/~yournamehere/nova/branch-name ... and click "Propose for merging" | 07:07 |
| fraggeln | is swift ready for production-use? | 07:07 |
| mtaylor | fraggeln: yes - and is already in production use in fact | 07:08 |
| anticw | we have clients with production use of it | 07:08 |
| fraggeln | anticw: what type of clients? | 07:08 |
| fraggeln | if you are allowed to talk about it that is :) | 07:09 |
| anticw | fraggeln: umm... we (cloudscaling) do consulting... client details aren't public yet | 07:09 |

| mtaylor | fraggeln: rackspace cloud files is running swift on the backend, AIUI | 07:10 |
| anticw | and some people other than rackspace have some fairly reasonable scale as well | 07:11 |

| anticw | mtaylor: what does bzr use for author details on a commit? | 07:16 |
| fraggeln | anticw, mtaylor : thanks :) | 07:16 |
| anticw | (sorry, i've avoided bzr like the plague with success thus far so am very ignorant) | 07:16 |
| mtaylor | anticw: the value from bzr whoami | 07:16 |
| anticw | mtaylor: is there a config to change that al la git? | 07:17 |
| mtaylor | anticw: it's ok - I've been avoiding git for the same amount of time but just recently had to start using it for something, so I an empathize | 07:17 |
| anticw | n, found it | 07:17 |
| mtaylor | anticw: run "bzr whoami 'You Name <your@emnail.com>'" | 07:17 |
| vishy | natti: you're welcome | 07:18 |
| * vishy is very frustrated with bzr's ability to cherry-pick | 07:19 | |
| vishy | or lack therof... | 07:19 |
| vishy | s/therof/thereof | 07:19 |
| mtaylor | vishy: you can cherry pickj | 07:20 |
| mtaylor | vishy: bzr merge -mrev1..rev2 other-branch | 07:20 |
| mtaylor | vishy: you have to give both a starting and ending rev for it to treat it as a cherry-pick merge | 07:21 |
| vishy | yes only it isn't really cherry picking | 07:21 |
| anticw | mtaylor: can i diff the branch i just pushed against where i cloned it trivially? | 07:21 |
| vishy | it doesn't keep revision information | 07:21 |
| vishy | it basically just treats it like you generated a patch file | 07:21 |
| mtaylor | vishy: that is true, and that also bugs me | 07:21 |
| mtaylor | vishy: it's _slightly_ better than a patch file, as it does at least grok file moves, etc. | 07:22 |
| anticw | im not sure about bzr, but some SCMs have to do that | 07:22 |
| anticw | because the state is basically a directed graph of hashes, so you can't take things out of the middle robustly without taking ancestors | 07:22 |
| mtaylor | anticw: yes | 07:22 |
| *** omidhdl has joined #openstack | 07:23 | |
| mtaylor | anticw: correct -that's the reason bzr doesn't really do cherry picking - bzr is all centered around the DAG impl | 07:23 |
| mtaylor | anticw: but as for your diff question ... there's a couple of ways to go about it | 07:24 |
| vishy | mtaylor: it really makes maintaining multiple branches difficult | 07:24 |
| anticw | vishy: push back on who created the work and have them recreate patches you can merge directly | 07:25 |
| mtaylor | anticw: but what you're looking for is bzr diff ancestor:path/to/branch | 07:25 |
| anticw | mtaylor: oh, i mean on the web ui | 07:25 |
| anticw | sorry | 07:25 |
| mtaylor | anticw: oh. heh. | 07:25 |
| mtaylor | anticw: the merge request you generate will generate a diff that shows what will be merged | 07:25 |
| anticw | i guess if i do propse it will do that | 07:25 |
| mtaylor | yup | 07:25 |
| vishy | git is way better at that in particular. It also allows for nice clean branches due to rebasing. And it generally seems to be a little smarter about merges and replaced files. | 07:26 |
| mtaylor | vishy: yeah - it's sort of about a workflow... I totally hear your complaint, but I find that the main key is to NEVER mix unrelated work into the same branch | 07:26 |
| anticw | git cherry diffs then reapplies though internally | 07:26 |
| vishy | mtaylor: that is great but we are basically maintaining three production branches and we need to pull fixes back and forth | 07:27 |
| mtaylor | yup. it's certainly not perfect... and not great at back-and-forth | 07:27 |
| * mtaylor doesn't particularly put much stock in the git approach to rebase/'clean branch' though | 07:28 | |
| mtaylor | but would LOVE if bzr could support cherry picking patches in the workflow you're discussing | 07:28 |
| mtaylor | you pretty much have to wind up making a branch that's a GCA of the production branches and then apply your patches to that and pull from that to the places it needs to go... sort of blows | 07:29 |

| mtaylor | ttx: sure | 07:37 |
| ttx | https://code.launchpad.net/~termie/nova/db_migration/+merge/46073 looks like a good candidate | 07:37 |
| ttx | already went into the Hudson washing machine once | 07:38 |

| * mtaylor loves hudson | 07:38 | |
| ttx | Also https://code.launchpad.net/~ed-leafe/nova/xs-password-reset/+merge/45537 has 4 "accepted", which should be considered sufficient | 07:38 |
| mtaylor | ttx: yup. first one looks good. | 07:39 |

| ttx | yay | 07:40 |
| * mtaylor flexes his muscles | 07:40 | |

| mtaylor | ttx: cool. thanks! I have to put these things on my calendar early so I can actually get to them | 07:44 |
| ttx | mtaylor: for the date... probably early October | 07:44 |
| mtaylor | cool. | 07:44 |
| mtaylor | ttx: you don't happen to know the next UDS date do you? | 07:45 |
| ttx | but that's still very much up in the air. | 07:45 |
| ttx | mtaylor: you can abuse the tentative release schedules to have a relatively good idea. If Mark doesn't come up with a fun version number that requires moving everything two weeks | 07:45 |

| * mtaylor never understands why they only announce them like, 3 months out | 07:47 | |
| ttx | Oh ! That's Budapest, probably the week of May 12th | 07:47 |

| ttx | vishy: sounds logical | 07:57 |
| vishy | and db_migration should convert austin -> bexar (not bexar - patches) | 07:57 |

| vishy | JordanRinke: any luck with that chardev issue? | 08:01 |
| JordanRinke | sandboxes used to create blueprints used to create recipes | 08:01 |
| JordanRinke | yeah, i just posted the "fix" | 08:01 |
| JordanRinke | not sure where to go with it though | 08:02 |

| ttx | soren: <vishy> for all you packaging people: python-netaddr needs to be added to depends and qemu-nbd needs to be added to sudoers | 08:07 |
| fabiand_ | I read in a blog post, that objects are immutable in swift. so I wonder if they ever get deleted? | 08:08 |
| JordanRinke | They are images from Anso, I rembered seeing raw conversion as part of the compute logs previously so I decided to try it | 08:08 |
| JordanRinke | and the virsh command ran | 08:08 |
| mtaylor | vishy: point me at anything you get in terms of multi-node testing - I REALLY want to get hudson/tarmac doing that sort of testing (pre-merge if possible) | 08:08 |
| vishy | JordanRinke: the new code automatically converts the images to qcow | 08:09 |
| mtaylor | ttx: I also pinged soren about that... although I suppose I could just get off my own ass and do it | 08:09 |
| vishy | so perhaps kvm doesn't actually want you to specify | 08:09 |
| ttx | mtaylor: I could just do it too | 08:09 |
| ttx | mtaylor: but I'm kinda busy today | 08:09 |
| *** adiantum has joined #openstack | 08:09 | |

| *** elasticdog has quit IRC | 08:10 | |
| ttx | mtaylor: can you ask for specific reviews to random BMPs in Nova ? | 08:10 |
| JordanRinke | yeah, want it here or on launchpad? | 08:10 |
| ttx | mtaylor: or do you need to be the proposer for that ? | 08:10 |
| vishy | JordanRinke: just tell me if it says that it is a qcow2 image | 08:10 |
| mtaylor | ttx: I don't think you need to be the proposer | 08:10 |
| mtaylor | ttx: lemme check | 08:10 |
| JordanRinke | indeed it does | 08:10 |
| vishy | yeah so kvm is R-tarded | 08:11 |
| ttx | mtaylor: I thought maybe members of the review team can | 08:11 |
| vishy | it actually booted if you changed it to raw? | 08:11 |
| mtaylor | ttx: it appears I can request review for branches I did not propose | 08:11 |
| ttx | oh, cool. You have 5 minutes ? | 08:11 |

| JordanRinke | no, but I could have my networking screwed up right now | 08:13 |
| JordanRinke | I am at home, can you link me nova-debug again? I will see if it is actually booting | 08:14 |
| vishy | JordanRinke: i think it isn't booting | 08:14 |
| vishy | can you change the line to read <driver name="qemu" type="qcow2"/> | 08:15 |
| vishy | and see if it still barfs | 08:15 |
| JordanRinke | hmm lsmod for kvm shows a count now, so I think it may have actually booted | 08:15 |
| JordanRinke | it was qcow2, i changed it to make it work, I can change it back and confirm though, hold. | 08:16 |

| JordanRinke | err, that was while still raw | 08:17 |
| JordanRinke | and ahh, i see the diff there with the qemu, hang on | 08:18 |
| vishy | JordanRinke: in my testing if i gave it a qcow2 and called it raw it would basically say it booted but not load the drive. You'll probably see a failed to mount root filesystem if you cat console.log with your raw change. | 08:19 |
| JordanRinke | failed with qemu/qcow2 | 08:20 |
| vishy | bleh | 08:21 |
| vishy | JordanRinke: same error? | 08:22 |

| mtaylor | ttx: ok. I made a branch adding that depend. I'm not in openstack-ubuntu-packagers, so I submitted a merge req | 08:25 |
| mtaylor | soren ^^ | 08:25 |
| ttx | mtaylor: will review | 08:25 |

| soren | vishy: (i.e. you local system and the one where you see this problem) | 09:37 |

| soren | vishy: Easy workaround: Disable apparmor. | 09:54 |
| soren | /etc/libvirt/qemu.conf (look for security_driver) | 09:55 |
| vishy | kind of odd that it only fails with two images though | 09:56 |
| vishy | testing the disable | 09:56 |
| soren | That's not why it fails. | 09:57 |
| vishy | oh? | 09:57 |
| soren | let me dig a little bit more. | 09:59 |
| soren | It's got to do with the name of the file, as it turns out. | 10:01 |
| vishy | disabling selinux did work btw | 10:01 |
| vishy | o rly? | 10:01 |
| soren | apparmor. | 10:01 |
| vishy | the name of the backing file or the front file? | 10:01 |
| soren | The front. | 10:01 |
| soren | /etc/apparmor.d/usr.lib.libvirt.virt-aa-helper | 10:01 |
| vishy | rofl, so because i used the name local? | 10:01 |
| soren | Well, because you didn't name it disk or something.qcow2 or whatnot. | 10:01 |
| soren | Or put it in /var/lib/eucalyptus... :) | 10:02 |
| *** MarkAtwood has joined #openstack | 10:02 | |

| vishy | so if i name the front file *.qcow2 it will work | 10:02 |

| vishy | hilarious | 10:03 |
| soren | That's my hypothesis. | 10:03 |
| vishy | i think you are right | 10:03 |
| vishy | b | 10:03 |
| vishy | because local failed both ways | 10:03 |
| vishy | now why didn't it crash on my local machine ... | 10:03 |
| vishy | because it was in my home dir? | 10:04 |
| vishy | @{HOME}/** r | 10:05 |

| colinnich | fabiand: no, that's not correct - objects are deleted as soon as you command it | 10:11 |

| fabiand | colinnich: are they really erased from the disk? | 10:11 |

| vishy | k doing that then | 10:13 |
| soren | vishy: It's an extended glob of sorts, not a regex, fwiw. | 10:13 |

| creiht | fabiand_, colinnich: re deletes, the file is deleted as soon as the DELETE call is made. a 0-byte tombstone is put in it's place to ensure that an older version of the file doesn't get replicated back (due to failure scenarios) | 13:54 |
| creiht | The tombstone will be deleted after reclaimation age has passed, which is 7 days | 13:54 |
| fabiand_ | creiht, thanks for this note :) It came up to my mind that the file might get truncated to free space. | 13:55 |
| creiht | fabiand_: yeah we don't currently support running rsyncd on a different port, but it probably wouldn't be difficult to add that as an option | 13:55 |
| *** aliguori has joined #openstack | 13:55 | |
| creiht | soren: sounds good to me :) | 13:55 |
| creiht | fabiand_: As an example, say you delete an object, but you had a node down when that delete was issued. When the failed node comes back online, it still has the old copy of the object. Replication could try to push that old copy out to the other nodes, but the newer tombstones on the other nodes will prevent that | 13:58 |
| *** arthurc has quit IRC | 13:58 | |
| creiht | eventually the other nodes will also replicate the tombstone to the node that had failed, and delete the old object | 13:58 |

| fabiand_ | creith, very nice solution ... in the beginning i was sceptical about the usage of rsync ... being able to specify the rsyncd port might enable the usage of swift without root | 14:00 |
| creiht | fabiand_: we keep thinking that we have to replace rsync, but we keep finding ways to make it work effectively :) | 14:01 |
| creiht | As to root usage, the services start as root, but then quickly drop priveledges to whatever user you have defined | 14:02 |
| creiht | root is needed to bind to port 80 or 443 | 14:02 |
| creiht | We also set a couple of rlimits in the kernel (like max file descriptors) on startup | 14:04 |

| annegentle | mtaylor: I can run nova-manage commands no problem | 17:35 |
| fabiand_ | jaypipes, are there thoughts about using some space by using some kind of "cow" technique when pushing images which are based on an already present image? | 17:35 |

| annegentle | installed via add-apt-repository ppa:nova-core/trunk (is that via deb?) | 17:37 |
| mtaylor | yes | 17:37 |

| jeffrey_taylor | Does it make more sense to have the load-balancers in front of the firewalls and then the proxies behind the firewalls for a Swift deployment across several data-centres? OR, should the proxies sit between the firewalls and load-balancers? | 21:03 |
| creiht | jeffrey_taylor: that sounds like a question for your network engineer :) | 21:05 |
| *** hadrian has joined #openstack | 21:05 | |
| jeffrey_taylor | creiht, that's me :S | 21:05 |
| creiht | hehe | 21:05 |
| jeremyb | the storage nodes talk to each other not the proxies right? | 21:05 |
| jeffrey_taylor | right | 21:05 |
| jeremyb | for replication, etc. | 21:05 |
| creiht | yeah | 21:05 |
| jeffrey_taylor | creiht, I've got a lot on my plate :P | 21:05 |
| jeremyb | and other services like container | 21:05 |
| creiht | jeffrey_taylor: we really don't have cross-datacenter replication yet in swift | 21:05 |
| jeffrey_taylor | creiht, I was going to go the vlan route | 21:06 |
| creiht | though it is planned | 21:06 |
| jeremyb | creiht: but if you have 5 DCs you could do a zone each | 21:06 |
| jeffrey_taylor | creiht, what about in the scenario of one DC. should the proxies be behind the firewalls or behind? | 21:06 |
| creiht | so the storage nodes need to be able to talk with each other | 21:06 |
| jeremyb | so, i was thinking on the train last night... | 21:06 |
| creiht | jeremyb: as long as you have the connectivity, sure | 21:06 |
| creiht | and can handle the latency | 21:06 |
| creiht | but we haven't done any optimizations for that scenario yet | 21:07 |
| jeremyb | if you have multi-region set up, the different regions will be different rings | 21:07 |
| creiht | jeffrey_taylor: short answer is that you probably want the firewalls in front of the proxies | 21:07 |
| jeffrey_taylor | creiht, thanks. Just wanted to confirm that train of thought :) | 21:08 |
| creiht | weather or not that is behind or in front of the lb is more up to you | 21:08 |
| jeffrey_taylor | creiht, Ya, I'm really conflicted on that. LB's in the front of the firewalls are fine to a point, but I think we'll need LB's for the proxies once we grow | 21:08 |
| creiht | though it seems more logical for the firewall to be outside the lb | 21:09 |
| creiht | but I'm not a network expert | 21:09 |
| jeremyb | so, if you know you're going to hit more spindles than you ever imagined you could move one spindle at a time to a new ring (in a new region) and eventually it's all moved (i guess you'd have to move the containers or objects too not just spindles. but at least you don't need to double your spindle count overnight | 21:09 |
| jeremyb | ) | 21:09 |
| jeffrey_taylor | creiht, you make a good point. Those FWs should be getting hammered and even if they are, they should be able to handle it. Back to the drawing board! | 21:10 |
| creiht | :) | 21:10 |
| *** flipzagging has joined #openstack | 21:10 | |
| jeremyb | flipzagging! | 21:10 |
| creiht | jeremyb: There are a couple of ways that have been discussed | 21:10 |
| jeffrey_taylor | shouldn't* | 21:10 |
| flipzagging | jeremyb: hi | 21:10 |
| jeremyb | creiht: is multi region cactus? | 21:11 |
| creiht | one of the first questions to ask is do you want it cluster wide, or optional on a per container basis | 21:11 |
| jeremyb | last i checked the bp said bexar | 21:11 |
| creiht | jeremyb: yeah we are going to have to move it to cactus | 21:11 |
| jeremyb | :/ | 21:11 |
| creiht | It is a hard problem :) | 21:11 |
| creiht | And things are busy | 21:11 |
| creiht | I think we are currently leaning towards it being optional on a per-container basis | 21:12 |
| creiht | so say you have cluster a, and cluster b | 21:12 |
| creiht | you could say some container in cluster a, should also have n replicas in cluster b | 21:12 |
| jeremyb | what about the rax keeps one region of a private cluster? still no idea if that would be available? | 21:12 |
| creiht | I don't know much about private clouds at rax | 21:13 |
| creiht | ok | 21:13 |
| creiht | wait | 21:13 |
| creiht | I see what you are asking now | 21:13 |
| creiht | so that is part of the idea | 21:14 |
| jeremyb | i mean i run on my own hardware and racks and then rax does one of the regions | 21:14 |
| creiht | in theory you have your private cluster, but could say that one container should also have some replicas in rax cloudfiles | 21:14 |
| jeremyb | right | 21:14 |
| creiht | that has been discussed | 21:14 |
| creiht | but no promises :) | 21:14 |
| creiht | and I think that would be ideal | 21:15 |
| jeremyb | btw, i've wondering and just now remembered... | 21:16 |
| jeremyb | are objects stored on disk raw? i.e. can i just less/cat/grep/etc. directly on the xfs path? | 21:16 |
| creiht | jeremyb: yes | 21:16 |
| jeremyb | iirc that is one of nelson's requirements | 21:16 |
| *** pvo_away is now known as pvo | 21:17 | |
| jeremyb | creiht: cool. same as i have now except i sometimes have to pipe to `gzip -d` | 21:17 |
| creiht | jeremyb: and you can use the tool swift-get-nodes to determine on which nodes and where on the filesystem a given db or file is supposed to be located | 21:17 |
| creiht | hehe | 21:17 |
| *** westmaas has quit IRC | 21:19 | |
| creiht | and swift-object-info will tell you all the information you need about a specific file (where it should be on other nodes, metadata, etc.) | 21:19 |
| jeremyb | so it reads xattrs? | 21:20 |
| jeremyb | and are xattrs part of the checksum? | 21:21 |
| creiht | the xattrs are not part of the checksum | 21:22 |
| creiht | and yeah it reads the xattrs | 21:22 |
| jeremyb | hrmmmm | 21:23 |
| jeremyb | so there's no integrity checking on the xattrs then | 21:24 |
| *** EdwinGrubbs has joined #openstack | 21:24 | |
| jeremyb | and they're not raided | 21:24 |
| creiht | the xattrs are stored on each copy of the object | 21:24 |
| jeremyb | right but if the read succeeds you don't know if it's good data or not | 21:25 |
| creiht | hrm | 21:25 |
| jeremyb | was there much discussion (or even a conscious decision) about not checksumming them? | 21:26 |
| jeremyb | also, what's the checksum algo again? | 21:26 |
| creiht | the checksum is the md5 hash of the object | 21:26 |
| jeremyb | ok, weak but short | 21:26 |
| creiht | Do you need something stronger there? | 21:27 |
| jeremyb | not atm but maybe at some point | 21:27 |
| creiht | It wouldn't be hard to change, if you are paranoid | 21:27 |
| creiht | S3 uses it as well | 21:27 |
| *** EdwinGrubbs has quit IRC | 21:28 | |
| *** EdwinGrubbs has joined #openstack | 21:28 | |
| jeremyb | well one scenario i've brought up here before (which I'm not actually implementing right now but may do in the future) is a ring of trusted nodes and a ring of untrusted storage nodes | 21:28 |
| jeremyb | so, trusted nodes would do all the services and sign stuff and also some storage | 21:28 |
| jeremyb | but there would be a pool of servers that are just storage | 21:29 |
| creiht | What problem are you worried about? | 21:29 |
| *** ctennis has quit IRC | 21:30 | |
| creiht | In general users don't have access to storage nodes | 21:30 |
| creiht | but maybe, I don't understand the issue that you are wanting to solve | 21:30 |
| *** hhoover has joined #openstack | 21:31 | |
| jeremyb | my idea (with no immediate plans) was to have people stick a $300 box with 4 sata bays in their houses or other not entirely secure places. that could be used as one region for swift and then have the other 2 regions in DC racks | 21:32 |
| creiht | jeremyb: but back to the metadata, what type of corruption are you worried about in the metadata | 21:32 |
| jeremyb | right, metadata | 21:32 |
| jeremyb | so, if content can go bad why not metadata? unless maybe xfs provides some protection for the metadata? | 21:33 |
| creiht | The main reason for the object checksum is to ensure that the data the user PUTs/GETs is the whole data | 21:33 |
| jeremyb | oh, not corruption? | 21:33 |
| creiht | It is used secondarily for that as well | 21:33 |
| creiht | we have auditors that double check that | 21:33 |
| jeremyb | right | 21:34 |
| jeremyb | i was thinking checksum the data and make that an xattr and then checksum all xattrs (including the object checksum) and store that in an xattr | 21:34 |
| creiht | It also wouldn't be hard to add to the auditors to double check the metadata | 21:34 |
| jeremyb | and then just have auditors compare the second checksum | 21:34 |
| *** hhoover has left #openstack | 21:35 | |
| jeremyb | (was double check the metadata meaning compare to another copy? because aiui they don't even talk to more than one copy at a time now) | 21:36 |
| creiht | jeremyb: and back to the public region thing, that is an entirely different problem :) | 21:36 |
| creiht | You might find something like tahoefs interesting | 21:36 |
| jeremyb | right | 21:36 |
| jeremyb | yeah, i looked briefly | 21:37 |
| jeremyb | are they still active? | 21:37 |
| creiht | jeremyb: yeah I was ensuing that we could add something like that, or have the auditors add the checksum | 21:37 |
| creiht | they seem to be active still, but I haven't followed it very closely | 21:38 |
| jeremyb | seems they have an update in sep 2010 | 21:38 |

| *** ctennis has joined #openstack | 21:42 | |
| creiht | We've talked about using reasure-coding in the backend of swift | 21:43 |
| jeremyb | i'm planning to have containers sharded on date so a container will only have a short read-write lifespan and then turns r/o when it's "full". then do a final "golden" backup of the r/o container and reduce replica count or even apply correction coding | 21:43 |
| creiht | It would be nice to have the same amount of durability, while using less space | 21:43 |
| creiht | but it also complicates things quite a bit | 21:43 |
| jeremyb | have you seen the hdfs erasure coding? | 21:43 |
| creiht | nope | 21:43 |
| jeremyb | http://wiki.apache.org/hadoop/HDFS-RAID | 21:44 |
| redbo | have you seen hdfs hold more than a couple billion files? me either. | 21:44 |
| redbo | :) | 21:44 |
| creiht | lol | 21:44 |
| jeremyb | no | 21:44 |
| jeremyb | of course not! | 21:44 |
| jeremyb | redbo: btw, is anything you wrote for the compression tests available for me to use? | 21:45 |
| creiht | jeremyb: storage is cheap :) | 21:45 |
| jeremyb | can middleware change the container or object name for read and write requests? (ideally before auth checks) | 21:46 |
| creiht | jeremyb: if we used erasure coding, you wouldn't be able to go the filesystem and cat out a file :) | 21:46 |
| redbo | the compression testing was never anything fancy. https://github.com/redbo/test-storage/blob/master/test-compress | 21:46 |
| creiht | jeremyb: middleware can do just about anything :) | 21:46 |
| creiht | jeremyb: and actually that is pretty much how the s3 compatibility layer works | 21:47 |
| jeremyb | creiht: i figured that would change the cattability | 21:47 |
| jeremyb | ahh, cool | 21:47 |
| vishy | mtaylor, soren: either of you here? | 21:47 |
| creiht | if you do something like erasure coding, then you are dealing with blocks, not files | 21:47 |
| vishy | have a question on how hudson does bzr bd | 21:47 |
| jeremyb | redbo: ohh, i was thinking you made some middleware or something | 21:49 |
| jeremyb | redbo: anyway, that may help, thanks | 21:49 |
| creiht | jeremyb: he was using that to try to determine if compression would even buy us anything | 21:49 |
| redbo | well, that was just to see how compressable files were | 21:49 |
| jeremyb | right, i remember. i just didn't know how you did it | 21:50 |
| redbo | It took all night to run on a drive | 21:51 |
| jeremyb | just took a spindle from production or what? | 21:52 |
| *** pvo is now known as pvo_away | 21:52 | |
| *** jguiditta has quit IRC | 21:52 | |
| redbo | from your previous conversation, I'm not too worried about metadata being invisibly corrupted. The nice thing about the auditor is making sure there aren't any sectors that die and are never read to find that out. | 21:53 |
| redbo | yeah | 21:53 |
| mtaylor | vishy: yup | 21:54 |
| jeremyb | redbo: so the auditor reads all attrs for everything it checks? | 21:55 |
| redbo | yeah, it has to read all the xattrs to unpickle them and get the hash | 21:56 |
| jeremyb | haha, it's a pickle?! | 21:56 |
| redbo | I can't remember if it's pickle or json | 21:56 |
| jeremyb | maybe pickle does some verification for you? | 21:56 |
| vishy | mtaylor: so I'm assuming it does the following: cd /trunk && bzr pull && cd /packaging && bzr merge lp:packaging && dch (some options here) && bzr commit && bzr bd --merge=True --export-upstream=/trunk | 21:57 |
| vishy | is that about right? | 21:57 |
| jeremyb | ok, i'm off for now | 21:57 |
| jeremyb | thanks redbo and creiht | 21:57 |
| creiht | np | 21:57 |
| mtaylor | vishy: pretty much - except the opposite way | 21:57 |
| mtaylor | wait -- actually - | 21:58 |
| mtaylor | sorry, soren changed things. | 21:58 |
| vishy | can you pastie the shell script? | 21:58 |
| mtaylor | vishy: it just branches packaging and does bzr bd - the packaging branch only has the packaging - so it grabs the tarball using uscan | 21:58 |
| vishy | mtaylor: ah ok, but it must have some magic for finding the current version number to update teh changelog? | 21:59 |
| mtaylor | vishy: I'm not sure how soren has it set up, at this point, tbh - the way I usually set this up is closer to what you were writing earlier | 22:00 |
| vishy | mtaylor: and I would need to generate the tarball as well so maybe i'll use your method | 22:00 |
| tr3buchet | i'm considering the modeling for multi-nic. So far I think adding a virtual_interfaces table to hold the macs for each instance and a public boolean to networks should be all that needs to change. thoughts? | 22:00 |
| * mtaylor likes my method better | 22:01 | |
| vishy | mtaylor: is there some magic in dch to make a changelog entry from the revision number of the other branch? | 22:01 |
| vishy | i suppose I could do it myself in a script, but if there is magic... | 22:01 |

| soren | mtaylor: I'm here now. | 22:17 |
| soren | mtaylor: What's up? | 22:17 |
| soren | vishy: Nope, sorry, that's not how we do packaging at all. | 22:19 |
| *** troytoman has joined #openstack | 22:19 | |
| soren | vishy: Two completely separate branches get stitched together and I add a changelog entry, build a source package, and upload. | 22:20 |
| vishy | soren: yeah mtaylor said that you didn't do it that way, do you have dch magic to get the bzr revnumber or some kind of shell script? | 22:20 |
| soren | vishy: Ok, so this is how it works: | 22:21 |
| soren | vishy: Whenever a new commit lands on trunk, hudson notices. | 22:21 |
| soren | vishy: It then builds the nova project. | 22:21 |
| soren | vishy: ..which triggers the nova-tarball project... | 22:22 |
| soren | vishy: ..which builds a tarball and triggers the nova-ppa project. | 22:22 |
| soren | Hang on, I'm going to look it up to make sure I don't lie. | 22:23 |
| soren | Ok. | 22:23 |
| *** pvo is now known as pvo_away | 22:24 | |
| soren | vishy: The nova-ppa project does the following: | 22:24 |
| soren | vishy: It grabs the most recent tarball from Hudson, deduces the version from its name. | 22:24 |
| soren | vishy: Unpacks the tarball.. | 22:24 |
| soren | vishy: ..checks out the packaging branch and slaps it on top. | 22:24 |
| soren | vishy: Adds a changelog entry corresponding to the bzr revision and target distribution series. | 22:25 |
| soren | vishy: Builds the source package. | 22:25 |
| soren | vishy: Uploads. | 22:25 |
| soren | vishy: http://paste.openstack.org/show/474/ | 22:26 |
| soren | vishy: Those are the gory details. With me so far? | 22:26 |
| vishy | ah gets it from the tarball | 22:26 |
| vishy | yup | 22:27 |
| soren | Yeah. | 22:27 |
| soren | Well, you could just do "bzr revno". | 22:27 |
| soren | ..but I wanted to actually match what the tarball says. | 22:27 |
| vishy | sure | 22:27 |
| soren | a) to avoid a race where the something new gets added to trunk in between nova-tarball and nova-ppa run. | 22:27 |
| soren | b) to keep the version string generation in one place. | 22:27 |
| vishy | what do you pass in to dch? | 22:28 |
| soren | dch --force-distribution --v "${pkgversion}" "Automated PPA build." -D $series | 22:28 |
| vishy | or do you generate the changelog manually? | 22:28 |
| soren | It's all in that pastebin. | 22:28 |
| vishy | oh cool | 22:28 |
| vishy | t | 22:28 |
| vishy | hs | 22:28 |
| vishy | x | 22:28 |
| soren | There's a couple of reasons why I do it this way. | 22:28 |
| vishy | gah, thx that is. enter key got stuck | 22:28 |
| * vishy is going to do the simple version to start | 22:29 | |
| soren | So, we (OpenStack) may want to consume nova trunk at a different pace than Ubuntu. | 22:29 |
| soren | ..but we want to collaborate on the packaging. | 22:29 |
| soren | That's easier if they're kept completely separate. | 22:30 |
| soren | The reason I do the tarball thing is to make the process of building these snapshots be identical to the process of building packages of final releases. | 22:31 |
| soren | building packages of final releases is always based on tarballs. | 22:31 |
| soren | I'd hate to be building awesome packages all along, but have the final packages such because some difference in the process caused a problem. | 22:31 |

| * creiht sighs | 23:47 | |
| creiht | do we have to go through this *again*? :) | 23:47 |
| letterj | soren: I believe that our guys have tried it both way and found that they wanted more control of the services. | 23:48 |
| *** adiantum has joined #openstack | 23:49 | |
| creiht | a.) There is a lot of configuration that needs to be done before starting services makes any sense on a new install | 23:49 |
| *** zul has quit IRC | 23:49 | |
| creiht | b.) We talked about having a default swift-one install that could install a working system on one machine, but that hasn't had any priority | 23:49 |
| letterj | No one has more operational experience running swift clusters than our ops guys. | 23:50 |
| soren | I'm just trying to understand here. Almost every single other daemon in Ubuntu and Debian is started by default. So when I see on that doesn't, it looks odd. | 23:51 |
| creiht | you said the same thing last time :) | 23:51 |
| soren | I'm sure I did. | 23:51 |
| soren | :) | 23:51 |
| soren | I'm glad I'm consistent :) | 23:52 |
| creiht | There may be a point some time in the future that it will make sense to do that, it just doesn't right now | 23:52 |
| soren | General style in Debian packaging is to enable stuff by default if there are good, safe defaults. "If you don't want the service running, dont' install it" sort of stuff. | 23:53 |
| soren | creiht: Fair enough. | 23:53 |
| soren | I'll make a note of that. | 23:53 |
| soren | This will probably be clearer once I try to run it more. | 23:53 |
| soren | So a "# We don't yet have a default configuration, so we can't start the deamons by default" sort of comment next to the dh_installinit --no-start stuff would be accurate? | 23:55 |
