notmyname | good morning | 16:25 |
peluse | good morning | 16:25 |
peluse | notmyname: I was about to suggest that akp look at https://launchpad.net/ubuntu/+source/swift/2.0.0-0ubuntu1 is that a valid place to go for the package? | 16:26 |
peluse | Kbee I mean | 16:26 |
akp | peluse: i have a different issue... | 16:26 |
notmyname | Kbee: peluse: the official source tarball is at https://launchpad.net/swift/+milestone/2.0.0 | 16:27 |
notmyname | Kbee: peluse: and openstack doesn't produce packages. that's up to the distros | 16:27 |
notmyname | Kbee: but "1.3" sounds like an odd versions number. that is, it's really old for swift (the server side), but not that old for the CLI. can you verify that you need to upgrade the server or the client? | 16:27 |
notmyname | akp: ya, I was looking for a link to share with you | 16:28 |
*** bkopilov has joined #openstack-swift | 16:28 | |
Kbee | notmyname: peluse: thanks.. so, there is no way to *upgrade* directly.. i need to uninstall and reinstall from source tarballs myself unless ubuntu releases a package for it right ? | 16:28 |
notmyname | akp: I'm not sure exactly what you're seeing with inconsistencies. but https://swiftstack.com/blog/2012/04/09/swift-capacity-management/ will give you a good overview of capacity management in swift | 16:29 |
creiht | Kbee: or manage your own packages if you don't want to wait for upstream | 16:29 |
notmyname | Kbee: there's not an "upgrade" button inside of swift. that being said, here's something that may help you out: https://swiftstack.com/blog/2013/12/20/upgrade-openstack-swift-no-downtime/ | 16:29 |
Kbee | creiht: :) .. notmyname: got it.. wanted to confirm once.. thanks | 16:30 |
Kbee | notmyname: Has swiftstack controller started pushing updates for 2.0 ..How frequent will be updates from swiftstack controller.. will it be always from top of master | 16:31 |
akp | thanks notmyname | 16:33 |
*** morganfainberg_Z is now known as morganfainberg | 16:33 | |
notmyname | Kbee: we're rolling that right now. and we push releses every two weeks. we track around master. that is, we push new swift versions fairly often instead of waiting for openstack integrated releases | 16:34 |
Kbee | notmyname: Thanks | 16:35 |
peluse | notmyname: yeah, thanks. I'll tuck that package location off for future reference -- someone asked before and I just told them to install from source :) | 16:42 |
notmyname | peluse: ya, that's just the source tarball. it's also mirrored on github. but there's always a source tarball on launchpad with every release | 16:42 |

*** shubhamsharma24 has quit IRC | 18:43 | |
shubhamsharma24_ | i am a newbie to opn source, i need some help ?? | 18:43 |
Kbee | shubhamsharma24_: What help do u need | 18:49 |
shubhamsharma24_ | project swift do excites me, and my main motive is open source contribution and gsoc 2015 | 18:50 |
shubhamsharma24_ | where can i start from ?? | 18:50 |
notmyname | shubhamsharma24_: cool, great to hear. are you participating in gsoc 2015? | 18:51 |
shubhamsharma24_ | yes i want to | 18:51 |
* notmyname doesn't know much about the gsoc logistics | 18:51 | |
notmyname | shubhamsharma24_: what do you know about swift today? | 18:52 |
shubhamsharma24_ | someone told me to chose between network , storage and virtualisation | 18:53 |
shubhamsharma24_ | i read in detail about each one of them and it's storage that excited me the most | 18:53 |
notmyname | shubhamsharma24_: cool. (me to) | 18:55 |
notmyname | *too | 18:55 |
shubhamsharma24_ | i have read https://wiki.openstack.org/wiki/Programs thoroughly | 18:55 |
shubhamsharma24_ | so tell me from where can i start ?? | 18:56 |
notmyname | shubhamsharma24_: I'm getting some links for you | 18:59 |
shubhamsharma24_ | that would be great :) | 18:59 |
notmyname | shubhamsharma24_: this is a little old (some things have changed with the code organization recently), but it's still pretty good https://swiftstack.com/blog/2013/02/12/swift-for-new-contributors/ | 19:00 |
notmyname | shubhamsharma24_: https://swiftstack.com/openstack-swift/architecture/ is a good one-page overview of how swift is designed | 19:00 |
shubhamsharma24_ | what next after the reading part ?? | 19:03 |
notmyname | shubhamsharma24_: what scale of task are you looking for? | 19:04 |
shubhamsharma24_ | patch submission | 19:05 |
notmyname | shubhamsharma24_: ya, but that could be big or small :-) | 19:06 |
shubhamsharma24_ | starting with small patches | 19:06 |
notmyname | shubhamsharma24_: so I can think of 3 things that would be nice and are fairly isolated and not too complex (probably) | 19:07 |
*** mariusv has quit IRC | 19:07 | |
shubhamsharma24_ | ok | 19:08 |
notmyname | shubhamsharma24_: (1) change the default ports (2) implement reverse listings (3) add stdin streaming support to the CLI | 19:08 |
shubhamsharma24_ | look the thing is i am a complete newbie, submitting patches is a thing i want to do but i am yet to get myself familiarized with the code | 19:10 |
notmyname | shubhamsharma24_: I understand | 19:10 |
shubhamsharma24_ | so wouldn't it be cool to start with the bugs ?? | 19:10 |
shubhamsharma24_ | and code familiarization ?? | 19:11 |
notmyname | shubhamsharma24_: the best 2 ways to learn about the code would be to look at current reviews (see the channel topic) and to write a patch | 19:11 |
notmyname | shubhamsharma24_: the 3 things I suggested earlier are fairly small starts on writing new things, and I can help guide you if you're interested in one of them. the bug list is on launchpad at https://bugs.launchpad.net/swift/ but those descriptions dont always have a well-defined scope that someone new can quickly pick up | 19:12 |

akp | is object data shifted when account and containers are shifteD? | 21:02 |
notmyname | akp: what do you mean by "shifted"? | 21:04 |
akp | i added an SSD and moved the account and container rings to it from spinning media | 21:08 |
notmyname | akp: that won't cause any of the object data to move around | 21:09 |
akp | hmm i am seeing the object count and total bytes not being consistent.... | 21:12 |
akp | should that concern me? | 21:13 |
notmyname | probably not :-) | 21:13 |
notmyname | akp: what are you expecting to see, and what are you seeing? | 21:13 |
akp | expecting to see the x-account-object-count to go up and x-account-bytes-used to slow go up as items are added. | 21:15 |
akp | but i've been seeing it flap up and down | 21:15 |
akp | sound normal? | 21:17 |
notmyname | akp: that's expected. or at least not indicative of a problem. it's one of the first places you'll see swift's eventual consistency. the account stats are updated asyncronously, so the updater processes that roll it up (combined with any replication going on, especially in the midst of capacity adjustment) can cause it to not return different values | 21:17 |
notmyname | akp: there are 3 account servers that could respond to your request. because of the differences in time on when their respective stats could be updated, you'll see different results if one request goes to one account server and another request goes to another | 21:18 |
notmyname | (and strictly speaking, it's the different account DBs, not servers. but normally that's the same thing if you have at least 3 servers in your cluster) | 21:19 |
notmyname | akp: make sense? | 21:19 |
akp | - digesting - | 21:20 |
akp | would having only 4 zones cause any issues? | 21:21 |
akp | 8 servers/4 zones | 21:21 |
akp | and on of the accounts has 80million objects | 21:22 |
akp | but yes. that over all makes sense. and i shouldn't be to concerned | 21:23 |
notmyname | akp: nope, no worries. it sounds normal to me | 21:23 |
notmyname | akp: and really, having more zones that replicas (eg 4 zones and 3 replicas) is good. in fact, it's better than the opposite for many of the processes in swift | 21:24 |
notmyname | akp: so it sounds like you're doing it right | 21:24 |
akp | so missing a bunch of x-accounts-bytes-used is kinda normal. and will eventually normalize | 21:28 |
akp | because i've been running it for a day. | 21:30 |
akp | sorry just a bit worreid. | 21:30 |
notmyname | akp: if you aren't doing anything else in that account it will stabilize. to the right value. if you are putting and deleting stuff, then you've got a moving target. if you need it to go faster, then you need to look at the updater and replication processes to make sure they are performing well | 21:31 |
akp | ok. thanks. it sounds like i am safe | 21:32 |
notmyname | acoles_away: https://review.openstack.org/#/c/79991/ A+ clean code. would review again | 21:32 |
notmyname | acoles_away: running tests now. looks good, I think | 21:32 |
notmyname | akp: you've just now moved to flash storage for the accounts and containers? | 21:33 |
akp | about 24 hrs ago | 21:33 |
akp | on these older nodes. | 21:33 |
akp | haven't actually had a chance to get to them until this weke, | 21:33 |
notmyname | akp: I'd expect that you'll see less of a consistency window in the flash media | 21:35 |
notmyname | akp: what version of swift are you running? | 21:36 |
*** bill_az has joined #openstack-swift | 21:36 | |
notmyname | akp: also, just checking, you aren't setting the db_preallocation value on the account or container right? (it shoudl either be set to "off" or jsut not in the config for flash media. it's good to have ti turned on for spinning media) | 21:38 |
notmyname | akp: (the default is off) | 21:38 |
akp | let me double check | 21:39 |
akp | yeah, its not in any of my confs | 21:43 |
notmyname | great | 21:46 |
notmyname | basically, it's bad for flash because it can make the volumes fill up with preallocated space. which is nice for linear writes on spnning drives, but doesn't do much other than waste space on SSDs | 21:46 |
notmyname | also HDDs are big and SSDs are small | 21:47 |
akp | =) | 21:47 |

*** fifieldt has joined #openstack-swift | 22:00 | |
notmyname | akp: good! I want you to feel good about swift :-) | 22:02 |
notmyname | akp: can I ask how you're using it? | 22:02 |
akp | sure | 22:04 |

notmyname | torgomatic: yup. we can't bump a requirement unless we go all the way up to the much newer one in global requiremnts https://review.openstack.org/#/c/110815/ | 22:38 |
torgomatic | notmyname: can the infra folks disable that check for Swift so we can land that patch? | 22:39 |

torgomatic | notmyname: ping | 23:38 |
notmyname | torgomatic: pong | 23:38 |
torgomatic | notmyname: I found a bug in the test for the sysmeta stuff; I'm going to push up a patch over it | 23:38 |
torgomatic | just a test bug, though | 23:38 |
notmyname | torgomatic: oh, good | 23:38 |
torgomatic | and then I'm going to +2 it | 23:38 |
torgomatic | (it's that unit test failure from the last time) | 23:38 |

notmyname | dfg_: for a net 3 line patch, https://review.openstack.org/#/c/111043/ was really hard for me to quickly understand | 23:38 |
notmyname | torgomatic: that looks like a fun timing bug | 23:39 |
torgomatic | notmyname: yeah, I was looking at like .000001 and stuff, seeing if the 5-digit truncation had anything to do with it... but as soon as I hardcoded timestamp to some particular value I pulled out of the air, it was immediately apparent | 23:40 |
openstackgerrit | Samuel Merritt proposed a change to openstack/swift: Enable object system metadata on PUTs https://review.openstack.org/79991 | 23:42 |
torgomatic | notmyname: ok, I pushed the requisite buttons | 23:42 |
notmyname | torgomatic: looking | 23:43 |
notmyname | torgomatic: can you look at the comment I left on dfg's patch? I want to make sure I understood it. | 23:44 |
torgomatic | notmyname: sure... afaict, dfg's patch fixes yet another of the ways that simplejson hurts us | 23:44 |
notmyname | torgomatic: right. that's kinda what I figured out. eventually | 23:44 |
torgomatic | or possibly not-simplejson, if the code was written assuming simplejson :) | 23:45 |
torgomatic | which is probably the case; simplejson would turn "123" (json) into "123" (python), whereas stdlib json would make it u"123" | 23:45 |
*** Midnightmyth has quit IRC | 23:46 | |
torgomatic | notmyname: but yes, your comment looks fine to me | 23:46 |
notmyname | torgomatic: ok, then I'll add a +2. well maybe I'll fix the commit message first | 23:46 |
