| pvc | it seems my server doesnt get the ip address from the metadata so icant ping it | 08:57 |
| stephenfin | kashyap: That's with 'hw_machine_type = x86_64=q35' and 'num_pcie_ports = 8' in '[libvirt]' | 08:57 |
| kashyap | stephenfin: No worries about the delay at all. Was just refrehsing my DevStack env (after the goddamned dentist visit) | 08:57 |
| pvc | hi anyone can help ? | 08:57 |
| pvc | Calling 'http://169.254.169.254/2009-04-04/meta-data/instance-id' failed [119/120s]: request error [HTTPConnectionPool(host='169.254.169.254', port=80): Max retries exceeded with url: /2009-04-04/meta-data/instance-id (Caused by NewConnectionError('<requests.packages.urllib3.connection.HTTPConnection object at 0x7f9b8ad30d30>: Failed to establish a new connection: [Errno 101] Network is unreachable',))] | 08:57 |
| kashyap | stephenfin: BTW, does the spacing affect at all? | 08:57 |
| stephenfin | kashyap: Spacing? | 08:58 |
| stephenfin | pvc: You'd have much better luck asking this on #openstack | 08:58 |
| kashyap | stephenfin: I mean, extra space between the config attribute values | 08:58 |
| stephenfin | kashyap: It shouldn't, no | 08:58 |
| kashyap | stephenfin: Excellent. So why I asked for '8' was: | 08:59 |
| stephenfin | kashyap: Well, between the key and value. I wouldn't be so sure about spaces between the stuff on the value side (i.e. x86_64=q35) because that's not handled by oslo.config | 08:59 |
| kashyap | stephenfin: libvirt will ignore '2', because it will anyway give four PCIe ports: one for disk, n/w interface, memory balloon and RNG device | 09:00 |
| kashyap | stephenfin: So setting '8' should give us a few extra ports for hot-plugging, etc. | 09:00 |
| kashyap | stephenfin: I see, noted | 09:00 |
| kashyap | Thanks for the quick test; great timing! | 09:00 |
| stephenfin | kashyap: Yup, I was thinking there was a lower bound on what you could set. I wonder if we should note that in the docs? | 09:01 |
| stephenfin | kashyap: though I guess it doesn't really matter, if we're being honest | 09:01 |
| kashyap | Noting in the docs will certainly be clearer | 09:03 |

| pooja-jadhav | ohk | 14:16 |
| pooja-jadhav | mriedem, efried: we can boot volume backed instance by two ways. 1. using --boot-volume 2. mentioned in the ref[1]https://docs.openstack.org/newton/user-guide/cli-nova-launch-instance-from-volume.html | 14:19 |
| mriedem | oh there are myriad ways to bfv | 14:20 |
| mriedem | don't forget image-defined bdms | 14:20 |
| pooja-jadhav | mriedem, efried: When i boot an instance using --boot-volume. it creates single entry in block_device_mapping table. while when i use using --block-device in that case it creates 2 entries(1 for image and 1 for volume) | 14:20 |
| mriedem | when you say --boot-volume do you mean --block-device? | 14:20 |
| pooja-jadhav | no | 14:21 |
| pooja-jadhav | --boot-volume (we need to passed bootable volume there) | 14:21 |
| pooja-jadhav | volume created by an image | 14:21 |
| cdent | "oh there are myriad ways to bfv" is the opening like to the poem that will get me the nobel prize for lit | 14:21 |
| cdent | but only after my editor corrects my typing | 14:21 |
| mriedem | pooja-jadhav: so this, "cinder create --image-id $IMAGE_ID --display_name=bootable_volume $SIZE_IN_GB" | 14:22 |
| *** ttsiouts has joined #openstack-nova | 14:22 | |
| mriedem | "When i boot an instance using --boot-volume. it creates single entry in block_device_mapping table. while when i use using --block-device in that case it creates 2 entries(1 for image and 1 for volume)" | 14:23 |
| mriedem | in the first case, the bootable volume is the root disk of the vm, it's the boot_index=0 bdm | 14:23 |
| mriedem | that's why there is 1 bdm | 14:23 |
| pooja-jadhav | issue i observed is: when i checked the instance created by above ref doc and tried to verifies is it BFV then as block device mapping gives me two entries. this method(is_volume_backed_instance) returns false | 14:23 |
| pooja-jadhav | mriedem: yes | 14:24 |
| mriedem | in the 2nd case, there is an ephemeral root disk on the compute host, not a volume, and then a blank non-bootable volume is attached to the vm where boot_index=None | 14:24 |
| mriedem | b/c it's not volume-backed | 14:24 |
| mriedem | if you want a volume-backed server, the root volume is specified with boot_index=0 | 14:24 |
| *** dtantsur is now known as dtantsur|brb | 14:24 | |
| mriedem | https://docs.openstack.org/nova/latest/user/block-device-mapping.html might be helpful | 14:24 |
| mriedem | re: boot_index "Setting a negative value or None indicates that the device should not be used for booting." | 14:25 |
| mriedem | from the example, | 14:25 |
| mriedem | "nova boot --flavor FLAVOR --block-device \ source=SOURCE,id=ID,dest=DEST,size=SIZE,shutdown=PRESERVE,bootindex=INDEX \ NAME" | 14:25 |
| mriedem | bootindex=INDEX Orders the boot disks. Use 0 to boot from this volume. | 14:25 |
| mriedem | "nova boot --flavor 2 \ --block-device source=volume,id=$VOLUME_ID,dest=volume,size=10,shutdown=preserve,bootindex=0 \ myInstanceFromVolume" | 14:26 |
| mriedem | ^ means boot from bootable volume $VOLUME_ID | 14:26 |
| mriedem | the size field should probably be omitted from that last example since i don't think it's used for a pre-existing volume | 14:27 |
| mriedem | the --block-device size field is only used when nova creates the volume and boots from it | 14:27 |

| pvc | just a quick question mriedem | 15:57 |
| pvc | what release does the cinder volume in-use state extension supported? | 15:57 |
| sean-k-mooney | mriedem: ah unforunetly i dont have any vgpu suff currently. | 15:57 |
| dansmith | mriedem: so do you think we squashed it? http://status.openstack.org/elastic-recheck/#1789484 | 16:00 |
| * prometheanfire should be testing vgpu 'soon' | 16:00 | |
| *** dtantsur|brb is now known as dtantsur | 16:01 | |
| mgagne | Lets say your Ironic instance only has 2 physical nics and you don't want a 3rd interface attached because it just wouldn't work. Would Nova check for this limitation and fail at the API level? | 16:04 |
| *** spartakos has quit IRC | 16:05 | |
| mriedem | pvc: let me go back to your original question: https://review.openstack.org/#/c/590188/ will not be backported upstream | 16:05 |
| mriedem | because it's for a feature | 16:05 |
| *** spartakos has joined #openstack-nova | 16:05 | |
| mriedem | even though it says it's a bug, it's a bug related to implementing a feature | 16:06 |
| pvc | i see thank you :) | 16:06 |
| mriedem | volume extend support was added in pike https://specs.openstack.org/openstack/nova-specs/specs/pike/implemented/nova-support-attached-volume-extend.html | 16:07 |
| pvc | yes but on LVM driver only. for rbd is not yet supported | 16:08 |
| mriedem | sure, that's not a bug though | 16:09 |
| mriedem | more specifically, it's supported for iscsi and fibrechannel volume types | 16:09 |
| mriedem | which is more than just lvm | 16:09 |
| pvc | yes do you have idea when is the implementation for rbd? | 16:09 |
| mriedem | the next patch in that series https://review.openstack.org/#/c/594273/ | 16:10 |
| mriedem | but the blueprint isn't approved - it has to be discussed during the weekly nova meeting | 16:10 |
| pvc | i see thank you so much for your time :) | 16:11 |

| openstackgerrit | Elancheran S proposed openstack/nova master: Add exact match aggregate image properties matcher/filter https://review.openstack.org/593167 | 17:09 |
| mgagne | ok, it seems it would fail on Ironic side with NoFreePhysicalPorts exception which would be mapped to a Bad Request at the Ironic API. This will be mapped to VirtualInterfacePlugException in Nova virt driver. There is a generic try catch in compute manager which will raise InterfaceAttachFailed. And API will map to HTTPInternalServerError | 17:10 |

| openstackgerrit | Elancheran S proposed openstack/nova stable/pike: Add exact match aggregate image properties matcher/filter https://review.openstack.org/599870 | 17:11 |
| sean-k-mooney | mgagne: not in all cases. i know cisco added a thing where you can attach more interfaces then avaialble to a ironic system via neutron turnk port extition | 17:12 |
| mgagne | sean-k-mooney: yes, I'm concerned about "flat" networks where there is no trunk involved | 17:12 |
| *** mchlumsky has quit IRC | 17:13 | |
| mgagne | and about the UX in case of failure. | 17:13 |
| sean-k-mooney | one thing i was not aware of and maybe you can clarify. do we today allow you to attach an interface to an ironic node after its deployed? | 17:13 |
| mgagne | yes | 17:13 |
| sean-k-mooney | mgagne: and if we execeed the available interfaces we get an error or silent failure today? | 17:14 |
| *** adrianc has quit IRC | 17:14 | |
| mgagne | if you have flat networks, Nova will fail with a 500 error without much information about the reason. This is what I understood from reading the code. | 17:15 |
| *** mchlumsky has joined #openstack-nova | 17:15 | |
| sean-k-mooney | and you would like to chage that to a vifplug exception | 17:15 |
| sean-k-mooney | well VirtualInterfacePlugException | 17:15 |
| mgagne | attach/detach for Ironic was added in Pike: https://docs.openstack.org/releasenotes/nova/pike.html#new-features (2nd item) | 17:15 |
| mgagne | sean-k-mooney: it would be a much better UX if the user got a 400 instead of a 500 | 17:16 |
| sean-k-mooney | so you want to make it a 400 calls bad request rather then a 500 server error as its an enduser error to try to attach more interface then phyically avaialble | 17:18 |
| mgagne | yes, anything in the 4XX range | 17:18 |
| mgagne | because I don't think it's a server side error from the user perspective | 17:19 |
| sean-k-mooney | i mean that seam reasonable. i think i reivewd or partly reviewd code from you on this topic | 17:19 |
| mgagne | could be 406, 409. I'm not an expert. | 17:20 |
| mgagne | so you are the person I want to be friend with =) | 17:20 |
| sean-k-mooney | im not an expert either but i dont think 409 or 406 is correct | 17:21 |
| sean-k-mooney | 406 is for content type mismatches e.g. server say i speak json and you give it xml | 17:22 |
| openstackgerrit | melanie witt proposed openstack/nova stable/pike: Add functional test for affinity with multiple cells https://review.openstack.org/599840 | 17:22 |
| openstackgerrit | melanie witt proposed openstack/nova stable/pike: Make scheduler.utils.setup_instance_group query all cells https://review.openstack.org/599841 | 17:22 |
| sean-k-mooney | 409 is for rases e.g. you tried to update something but someone else also did please retry | 17:22 |
| mgagne | so 400 looks fine | 17:22 |
| mgagne | or 402 if you want to make them pay for that feature =) | 17:23 |
| sean-k-mooney | mgagne: i would use 400 or 418 if you are felling exotic or british | 17:25 |
| sean-k-mooney | i would be tempted by 412 but i would have to read rfc 7232 so see if its correct or not | 17:26 |
| mgagne | hehe so my question is how to raise that exception from Ironic to Nova API without losing much details. | 17:26 |
| *** dtantsur is now known as dtantsur|afk | 17:26 | |
| mgagne | because Ironic returns a 400 too but the error message would need to be parsed to find the reason and map it to something else in Nova. | 17:27 |
| mgagne | and I'm not sure it's the right way to do it | 17:28 |
| sean-k-mooney | i have to runn but a 400 with an embeded error code in the body might be the best option. this has been a topic dhellmann might be able to advise on. i think he had a session in vancouver on having consitent behavor in our error handling | 17:28 |
| sean-k-mooney | if the api does not return a 400 already then that is proably enough | 17:29 |
| mgagne | can we just assume that all 400 returned by Ironic are user errors at the Nova API level? | 17:29 |
| sean-k-mooney | not all responces but perhaps for that specific endpoint + http method | 17:31 |
| mgagne | +1 | 17:31 |
| *** munimeha1 has joined #openstack-nova | 17:33 | |
| jroll | mgagne: you need to go through scheduling to be able to determine if the node you pick has enough NICs, so I don't think it can ever be a synchronous error in the API | 17:36 |
| mgagne | jroll: we are talking about the hotplug feature ;) | 17:37 |
| jroll | ah | 17:37 |
| jroll | you still need to reach down into the virt driver, right? which is always async | 17:37 |
| melwitt | it's not always async -- depends on whether it's a cast or a call | 17:37 |
| melwitt | it's usually async though | 17:38 |
| mgagne | this is not what I found? or I misunderstood? | 17:38 |
| jroll | well, so much for being well-informed :) | 17:38 |
| melwitt | for example, when we do an attach_volume, we call down to the driver synchronously first to see if there's room, and fail in the API if not | 17:38 |
| melwitt | something I learned recently | 17:38 |

| mgagne | https://github.com/openstack/nova/blob/master/nova/compute/rpcapi.py#L465-L474 | 17:40 |
| mgagne | call() is used | 17:40 |
| jroll | mgagne: ah, cool, so I guess what I would do is add some sort of "NoNicsAvailable" exception that the ironic driver can return in this case | 17:40 |
| melwitt | thanks, was just looking for that | 17:40 |
| melwitt | indeed, call is synchronous | 17:41 |
| dansmith | this would be a call to compute which does an http call to ironic, yeah? | 17:42 |
| mgagne | jroll: there is already an exception for that (NoFreePhysicalPorts which is mapped to Invalid) https://github.com/openstack/ironic/blob/master/ironic/drivers/modules/network/common.py#L170-L174 | 17:42 |
| melwitt | dansmith: I think they'd add something to the already-existing synchronous attach_interface call to call ironic | 17:43 |
| mgagne | compute does a call to virt driver which performs the HTTP call: https://github.com/openstack/nova/blob/master/nova/virt/ironic/driver.py#L1450-L1451 | 17:43 |
| jroll | mgagne: oh, I meant add that exception to nova, so we can return it here: https://github.com/openstack/nova/blob/master/nova/virt/ironic/driver.py#L1474 | 17:44 |
| dansmith | yeah the unfortunate bit there is that if the second call takes a long time, we'll time out, report to the user that it failed, but eventually it succeeded | 17:44 |
| *** ccamacho has quit IRC | 17:44 | |
| dansmith | but, maybe this would be a good application of my long-call stuff | 17:45 |
| jroll | or add VirtualInterfacePlugException to the list here: https://github.com/openstack/nova/blob/master/nova/api/openstack/compute/attach_interfaces.py#L134 | 17:45 |
| mgagne | jroll: yes! just need a way to detect this kind of error from Ironic API response and map accordingly | 17:45 |
| melwitt | dansmith: ack | 17:45 |
| jroll | mgagne: yep, this is where someone says all API errors should have a "code" :) | 17:45 |
| mgagne | jroll: it's mapped to InterfaceAttachFailed in the compute manager https://github.com/openstack/nova/blob/master/nova/compute/manager.py#L5956 | 17:46 |
| mgagne | which is handled already here https://github.com/openstack/nova/blob/master/nova/api/openstack/compute/attach_interfaces.py#L149 | 17:46 |

| cdent | Is "thin provisioning" of disk mostly a vmware thing, or does it also happen when using some other hypervisor+storage things? | 21:06 |
| dansmith | cdent: other things have it | 21:08 |
| dansmith | not everything amazing is made by vmware. JEEZ | 21:08 |
| dansmith | a unix sparse file is kinda thing provisioning and pre-dates a lot of stuff | 21:09 |
| *** r-daneel has quit IRC | 21:09 | |
| dansmith | like 3.5" floppies | 21:09 |
| cdent | the reason I ask is I'm wondering how appropriate it is to consider dynamically adjusting allocation_ratio on DISK_GB in that sort of setting: compare actual versus perceived usage | 21:09 |
| dansmith | *thin | 21:09 |
| dansmith | cdent: well, it's not really the same thing | 21:10 |
| dansmith | it's similar | 21:10 |
| cdent | also: dansmith you know I hate everything, so I don't think anything from vmware is amazing | 21:10 |
| dansmith | but technically thin provisioning can blow up in your face if you overcommit | 21:10 |
| cdent | right, that's exactly the issue | 21:10 |
| dansmith | I do know that. | 21:10 |
| dansmith | IMHO, allocation_ratio can only be over 1.0 for disk if you like to gamble | 21:11 |
| dansmith | and shouldn't really be related to use of thin provisioning, | 21:11 |
| dansmith | except in that it may be the mechanism by which you gamble | 21:11 |
| cdent | the nearby concrete problem here is: datastore with 50TB total, allocated to 50TB, but in reality has 41TB free because of "thing provisioning" | 21:12 |
| * dansmith senses mockery | 21:12 | |
| dansmith | but yep | 21:12 |
| cdent | so the short term fix is bump allocation_ratio and watch real usage "real close like" | 21:12 |
| dansmith | yeah, i.e. gambling | 21:12 |
| cdent | that was not mockery, I just can't type | 21:12 |
| cdent | which you also know | 21:12 |
| dansmith | so, every night before the op goes to sleep, | 21:12 |
| dansmith | he decides how far he thinks he can get before 8am the next morning and sets the allocation_ratio accordingly | 21:13 |
| cdent | pretty much | 21:13 |
| dansmith | solid plan | 21:13 |
| cdent | so the questioning is: if you know what placement thinks about usage, and you know what the datastore thinks of its free space, you ought to be able to calculate a dynamic allocation ratio every now and again, and save that op some sleep | 21:14 |
| dansmith | if your usage is very consistent | 21:15 |
| dansmith | the other thing to think about/remember is: | 21:15 |
| dansmith | thin provisioning is somewhat of a space-saving thing, but it's also just to speed up the actual provisioning step | 21:15 |
| dansmith | most filesystems will end up filling out the block device over time, | 21:16 |
| cdent | yeah, which is why it would need to be a failure regular thing | 21:16 |
| dansmith | unless they intentionally compact and fstrim() now and then to let go of things back to the underlying storage | 21:16 |
| cdent | like maybe every update_provider_tree | 21:16 |
| cdent | that was an awesome freudian slide on my part: meant fairly, but failure works too | 21:17 |
| dansmith | but if you go to sleep with it set at 1.1, | 21:17 |
| dansmith | and something happens where a big tenant has a script that runs amok and fills the disk with logs, | 21:17 |
| dansmith | you could end up getting a page | 21:17 |
| dansmith | so it's still a ticking time bomb, even if you calculate a conservative ratio based on recent history | 21:17 |
| cdent | I'm not sure I'm following that logic: at time 1 we set it to 1.1. a few minutes later the actual usage on the store goes up, so at time 2 we set it to 1.0 | 21:18 |
| cdent | if 1 and 2 are close together the risk is lessed (but not entirely removed) | 21:18 |
| dansmith | you mean some automated thing that looks for the crash on the horizon and adjusts the ratio before it becomes a problem? | 21:19 |

| *** macza_ has joined #openstack-nova | 21:19 | |
| dansmith | I'm trying to think about how that helps | 21:21 |
| cdent | in this vmware case the datastore knows how many bytes it says it has "free". this is different from what placement says. The ratio of that difference can be a multiplier for setting allocation_ratio. If you're saying "the datastores sense of 'free' is not real" then yeah, sure, we got a problem. | 21:21 |
| dansmith | until you get to 1.0, it might as well be 1.0, and once you're past 1.0 you can't go back | 21:21 |
| *** macza has quit IRC | 21:22 | |
| *** dklyle has quit IRC | 21:22 | |
| dansmith | it's free to the datastore, but it's not "uncommitted" | 21:22 |
| cdent | I think that may be where the vmware stuff is actually doing something "amazing" that is a bit different from sparse files | 21:22 |
| dansmith | the other two things that it can be doing are compression and dedup | 21:23 |
| *** itlinux has quit IRC | 21:23 | |
| dansmith | both of which have an optimal ratio, but that aren't consistent | 21:23 |
| dansmith | like, if your users are into storing usenet archives, you might get 1.5x from compression, but if they're archiving "those" usenet articles, it'll be much closer to 1.0x | 21:24 |
| *** r-daneel has joined #openstack-nova | 21:24 | |
| dansmith | and if multiple tenants are storing the same things, then you might get 2x from dedup, but not if they're using different block sizes or encruption | 21:24 |
| dansmith | *encryption | 21:24 |
| dansmith | dang | 21:24 |
| dansmith | you know. | 21:24 |
| cdent | yah, all that makes sense | 21:25 |
| cdent | but the fundamental issue here is 41TB free, but placement says no bytes free | 21:25 |
| cdent | *issue for the customer | 21:25 |
| dansmith | right, I get that | 21:25 |
| dansmith | 41TB is free because 41TB hasn't yet been used, | 21:26 |
| dansmith | but it _is_ committed to some instances | 21:26 |
| dansmith | according to nova and placement | 21:26 |
| cdent | and for many of these flavors, probably never will, because somebody made big flavors, and people like big things even when they don't need them | 21:26 |
| cdent | yes to all that | 21:27 |
| dansmith | you can tell placement to oversubscribe that to converge the two numbers to zero, but the end result will be someone writes a byte to disk and gets an EIO because you lost the bet | 21:27 |
| dansmith | yeah, but again, with disk, it all ends up filling out | 21:27 |
| dansmith | if you have a linux guest with a 1TB disk and 500MB used, | 21:27 |
| dansmith | and you write a 10MB file and then delete it, in a loop, | 21:27 |
| dansmith | you will end up touching all sectors on the disk | 21:27 |
| dansmith | if you're fstrim()'ing then that will tell the underlying disk that you're only using some of those at a time, | 21:28 |
| dansmith | but if you're not, it doesn't know | 21:28 |
| dansmith | now, I'll grant you this: | 21:28 |
| cdent | as I understand things, in the vc situation, the datastore will reject a workload if _it_ thinks it doesn't have enough space to cope | 21:28 |
| cdent | so it's not going to lead to that level of disaster, at least not as quickly | 21:28 |
| dansmith | if the expectation or requirement is that the guest agent is running in all these instances and can ensure that it's trim'ing then you won't converge on full in the same way | 21:28 |
| cdent | the split brain nature of the vc situation, sets up a lot of weird | 21:29 |
| dansmith | based on what logic? | 21:29 |
| cdent | vmware magic? | 21:29 |
| cdent | it's what that stuff does. who knows how it works. | 21:29 |
| dansmith | well, unless you can explain some magic, I don't believe :) | 21:30 |
| cdent | let me see if I can find something | 21:30 |
| mriedem | https://www.youtube.com/watch?v=1-bt81UBDLI ? | 21:30 |
| cdent | hrmm, too many layers of indirection | 21:34 |
| cdent | so: in the general case a fix for this kind of thing is: train people to not use big disk using flavors when they don't need that. use a volume. | 21:34 |
| dansmith | I'm not saying you shouldn't gamble, | 21:35 |
| dansmith | I'm just saying if you do, be sure to let me know so I can move my instances elsewhere :) | 21:35 |
| dansmith | I think most probably do because they're economizing, and they take that risk, mitigated by willingness to throw disks at a growing problem | 21:36 |
| dansmith | if you're going for risk-and-reward, you gamble | 21:36 |
| dansmith | if you're going for "make sure the nukes don't EIO at a bad time" then maybe you don' | 21:37 |
| dansmith | t | 21:37 |
| cdent | aye aye | 21:38 |
| cdent | still querying around for an answer on the "is there magic here" and so far the answer is "it's complicated" | 21:38 |
| cdent | and that, kids, is why grampy chris hates everything | 21:38 |
