| cnf | cinder can't expose iscsi or nfs, can it? | 12:48 |
| *** alonma has quit IRC | 12:48 | |
| smcginnis | cnf: Cinder doesn't expose anything. It manages backend devices that do things like iSCSI, NFS, RBD, etc. | 12:48 |
| *** alaski is now known as lascii | 12:49 | |
| cnf | hmm, so how do you store things on cinder? | 12:49 |
| cnf | how do you consume it? | 12:49 |
| smcginnis | cnf: You don't "store things on cinder". Cinder is used to provide a common management abstraction (API) across different backend storage types. | 12:50 |
| smcginnis | cnf: So you still need something to be the actual storage, whether that's LVM, VMFS, or some other external storage device. | 12:50 |

| cnf | uhm | 12:51 |
| cnf | smcginnis yes, you need storage, but i though cinder was the API to the storage | 12:52 |
| *** ducttape_ has quit IRC | 12:52 | |
| smcginnis | cnf: Yes. I'm being a little extra technically specific here to make sure there's not a misunderstanding. | 12:52 |
| smcginnis | cnf: It is the API to the storage. | 12:52 |
| smcginnis | cnf: It is not the data path to the storage. | 12:53 |
| cnf | so I have a system with a ZFS pool, on which I can run cinder, and give it part of that pool | 12:53 |
| smcginnis | API == REST, data path == [iSCSI|FC|NFS|RBD|...] | 12:53 |
| cnf | ok, so the only api is rest? | 12:53 |
| smcginnis | You could use LVM on that system. | 12:53 |
| cnf | and ESX doesn't do rest :P | 12:53 |
| smcginnis | cnf: REST is the management API. It is not the data path. | 12:54 |
| smcginnis | Trying to be clear - Cinder is not a storage device. | 12:54 |

| smcginnis | cnf: Can't find a good reference to point to. | 12:56 |
| smcginnis | cnf: Think of it this way, Cinder is a management tool. It manages different storage devices. | 12:56 |
| cnf | but how do you write to the storage device? | 12:56 |
| smcginnis | cnf: And that's it. How consumers use that storage is for the most part out of the realm of Cinder. | 12:56 |
| smcginnis | cnf: The consumers of the storage access the data, to do writes and reads, just like they would even if Cinder was not present. | 12:57 |
| smcginnis | cnf: Cinder just helps get things configured and provisioned. | 12:57 |

| cnf | hmm, I don't understand the use of that | 12:58 |
| sbezverk | good morning. when I start cinder volume process in kubernetes environment, I see this traceback http://paste.openstack.org/show/566067/ but other services like api and scheduler are starting fine. Appreciate if somebody could check it and let me know what could have caused it. | 12:59 |
| smcginnis | sbezverk: Looks like maybe an issue with the database? | 13:00 |
| cnf | so if I have a cinder node with LVM, and a nova node elsewhere, the nova node can't actually use the storage on the cinder node? | 13:00 |
| cnf | because LVM has no network capabilities of itself | 13:00 |
| smcginnis | cnf: Key point there is "with LVM". | 13:00 |
| *** andymaier has joined #openstack-cinder | 13:00 | |
| xyang | @smcginnis: you may need to do db sync | 13:01 |
| sbezverk | @smcginnis: I would think so too, but since api and scheduler are working I was not sure how it could be possible.. | 13:01 |
| cnf | well, that still means your compute node needs to understand whatever api your storage nodes speak | 13:01 |
| smcginnis | cnf: LVM isn't just LVM by itself. It's also iscsi target. So the connectivity is iSCSI to that storage. | 13:01 |
| smcginnis | Standard iSCSI. | 13:01 |
| xyang | sbezverk: did you do db sync after updating the code | 13:01 |
| sbezverk | xyang: dbsync was run right after db creation, in bootstrap process | 13:02 |
| cnf | hmm, then I guess I can just scrap cinder off my list of posibilities | 13:02 |
| xyang | sbezverk: I see an errnor that it can't find a table. I wonder if you had the code earlier, updated the code, but didn't run db sync again | 13:02 |

| *** EinstCrazy has quit IRC | 14:52 | |
| jgriffith | sbezverk: I'm unclear why you see it in your k8's case though and we don't typically encounter it | 14:53 |

| mtanino | jgriffith: Did you find a solution? | 15:34 |
| *** Dinesh_Bhor has quit IRC | 15:34 | |
| jgriffith | mtanino: I find it interesting that oslo.concurrency set ignore_exit_code to False by default, but sets check_exit_code to False as default as well | 15:34 |
| jgriffith | mtanino: yeah... so the problem I believe is that the case there provides an unexpected exit_code, so we fail in putils | 15:34 |
| jgriffith | mtanino: but masking out to always just ignore means we should inspect the output | 15:35 |
| jgriffith | so I'm working on adding that now | 15:35 |
| *** crose has quit IRC | 15:35 | |

| jgriffith | smcginnis: it's not a very *friendly* module | 18:07 |
| jgriffith | :) | 18:07 |
| jgriffith | mostly just that thing in "libs" seem to make life harder these days. | 18:07 |
| jgriffith | I kinda like the old model of having the autogenerated copies of things in tree | 18:08 |
| jgriffith | but to answer your question seriously... NO I don't really know of a technical reason | 18:08 |
| jgriffith | other than whether or not it works for Nova and I don't know the answer to that | 18:08 |
| *** rlrossit has joined #openstack-cinder | 18:09 | |
| smcginnis | jgriffith: Yeah, I don't like duplication, but if things are automated to make sure fixes make it everywhere then that makes things a little easier. | 18:09 |
| jgriffith | duplication isn't bad... everybody loves cloning and replication :) | 18:09 |
| smcginnis | It is a bit of a pain when you find an issue, have to wait for it to merge in the lib, wait for the requirements to get updated, wait to get it pulled into the project, then finally get the fix. | 18:09 |

| jgriffith | eharney: what's the -1 for? | 18:13 |
| *** ducttape_ has quit IRC | 18:13 | |
| eharney | jgriffith: you can set an env variable to hide the LVM fd message instead of us having to filter it out | 18:13 |
| jgriffith | eharney: well shit | 18:13 |
| eharney | jgriffith: just stick LVM_SUPPRESS_FD_WARNINGS=1 in the LVM_CMD_PREFIX list | 18:14 |
| jgriffith | eharney: I should've remembered that from the last time we did one of these | 18:14 |
| eharney | jgriffith: but looking at the lvm code i don't understand the bug anyway, because that message doesn't look like it should cause failures | 18:14 |
| *** _ducttape_ has quit IRC | 18:14 | |
| jgriffith | eharney: it does because oslo.concurrency see the ec and raises | 18:14 |
| *** xyang has quit IRC | 18:15 | |
| eharney | jgriffith: just because it prints to stderr, or because it returns non-zero? | 18:15 |
| jgriffith | eharney: exit code.... https://github.com/openstack/oslo.concurrency/blob/master/oslo_concurrency/processutils.py#L300 | 18:16 |
| eharney | jgriffith: humm, i was just reading the lvm code to see how it worked and it looked like it should still return 0... guess i should try it | 18:16 |
| jgriffith | eharney: hmm... well yep, there we have it http://lists.linuxfromscratch.org/pipermail/blfs-support/2015-March/076491.html | 18:18 |
| jgriffith | sbezverk: ^^ | 18:18 |
| eharney | also in "man lvm" :) | 18:20 |
| jgriffith | eharney: what's "man" :) | 18:20 |
| eharney | jgriffith: my other note was that it should apply to all LVM commands and not just "vgs", but the easy way to set the variable will handle that anyway | 18:20 |
| jgriffith | eharney: well, that particular issue (on Ubuntu) is actually the VGS cmd only | 18:21 |
| jgriffith | eharney: but as LVM bugs go, you're probably right | 18:21 |
| eharney | strange, since the lvm code seems to run that check for all commands | 18:21 |
| eharney | i'm concerned that it's failing for a different reason that you aren't seeing in the logs | 18:22 |
| eharney | jgriffith: what version of the lvm/lvm2 package do you have? | 18:22 |

| jgriffith | eharney: sbezverk seems to hit it every time in his kubernetes setup | 18:23 |
| jgriffith | eharney: probably something with the shared device files or something along those lines is my belief | 18:24 |
| jgriffith | eharney: so I'm wondering if it should be a config option for now or not? | 18:24 |

| jgriffith | eharney: but ignore_exit_code defaults to False as well | 18:27 |
| eharney | jgriffith: yeah, but i can't see where the lvm command is creating a non-zero code from that warning | 18:28 |
| jgriffith | eharney: well it's in the trace IIRC | 18:28 |

| jgriffith | eharney: http://paste.openstack.org/show/566086/ | 18:28 |
| eharney | jgriffith: it's failing because "Volume group "cinder-volumes not found", not because of the fd leak warning | 18:29 |
| jgriffith | eharney: nope | 18:29 |
| jgriffith | eharney: incorrect | 18:29 |
| eharney | jgriffith: that's what that trace says? | 18:29 |
| jgriffith | eharney: oh... you mean the ec is because there's no vol? | 18:29 |
| jgriffith | err... vg | 18:29 |
| eharney | jgriffith: yes | 18:29 |
| jgriffith | oh.. right | 18:29 |
| jgriffith | I see | 18:29 |
| eharney | jgriffith: it's just hard to find because of all of that junk in front of it (which we should fix) | 18:30 |
| jgriffith | well, no I get that | 18:30 |
| eharney | the fd leak message doesn't actually cause an error | 18:30 |
| jgriffith | eharney: yeah, see what you're saying | 18:32 |
| jgriffith | eharney: so might be masking out something there that just makes it so we fail later | 18:32 |

| jgriffith | eharney: but yeah... that warning mesg isn't actually causing a problem it doesn't appear | 18:44 |
| jgriffith | eharney: so you are certainly right about that it seems | 18:44 |
| eharney | jgriffith: now i'm just wondering how this wasn't breaking all the time if it fails when the answer would be False | 18:45 |
| jgriffith | eharney: so what happens is the service never starts | 18:45 |

| *** alonma has quit IRC | 18:47 | |
| jgriffith | so that's "not good" but at least correct | 18:47 |
| patrickeast | thats been a thing for as long as i've been working on openstack, if you accidently screw up your devstack config and have the wrong 'enabled_backends' set it defaults to lvm driver but the vgs never get created by devstack | 18:48 |
| jgriffith | patrickeast: :) | 18:48 |
| patrickeast | and you get an lvm backend that gets stuck in down | 18:48 |
| patrickeast | then you've gotta go change cinder.conf and edit the db to get rid of the lvm one | 18:48 |
| jgriffith | patrickeast: I kinda remember at one point we'd vomit, but people didn't want to do that incase somebody *fixed* it later | 18:49 |
| patrickeast | haha | 18:49 |
| patrickeast | that makes sense i suppose | 18:49 |
| jgriffith | patrickeast: by fixed I mean "added in the vg" later | 18:49 |
| jgriffith | but I don't even know that that would work anyhow | 18:49 |
| patrickeast | yep, if you actually did want to use lvm that seems like the right thing to do | 18:49 |
| patrickeast | right idea anyway | 18:50 |
| jgriffith | it was one thing to add it to drivers IMO but the vg for the driver is kinda sketch | 18:50 |
| jgriffith | anywho... eharney I think that second error is in fact a real scheduling problem | 18:50 |
| *** ducttape_ has quit IRC | 18:50 | |
| eharney | jgriffith: i think we fixed it already | 18:50 |
| jgriffith | eharney: its' just become really difficult (IMO) to read the logs and figure that out with all the xtra obj noise | 18:51 |
| jgriffith | eharney: you can't fix it | 18:51 |
| *** kfarr has quit IRC | 18:51 | |
| jgriffith | eharney: if the VG isn't there and there's no extents it can't create | 18:51 |
| jgriffith | eharney: you see what I mean? | 18:51 |
| jgriffith | eharney: so let me back up... | 18:51 |
| eharney | jgriffith: oh, not sure what error you are referring to | 18:51 |
| *** ducttape_ has joined #openstack-cinder | 18:52 | |
| jgriffith | eharney: that second error/trace is WITH my hack that masks out the warning message | 18:52 |
| jgriffith | eharney: it would appear that inadvertantly does *something* that causes the service to report as enabled/up | 18:52 |
| sbezverk | jgriffith: do you think second issue is related to your fix?? | 18:52 |
| jgriffith | eharney: I'm pretty confident that it is yes | 18:52 |
| jgriffith | eharney: because without that broken fix you'd never be able to try and schedule anything | 18:53 |
| jgriffith | eharney: but with it, it appears it's accepting requests :( | 18:53 |
| jgriffith | eharney: i haven't figure out how/why that is yet though | 18:53 |
| sbezverk | jgriffith: I can enable extra logging if you think it could help, since in my test bed it is reproduced every time | 18:54 |
| jgriffith | sbezverk: so the first thing is you should revert my patch :( | 18:55 |
| jgriffith | sbezverk: second is how come the VG isn't there? | 18:55 |
| jgriffith | sbezverk: the root does seem to be just that the VG doesn't exist I think | 18:55 |
| sbezverk | jgriffith: VG is there | 18:55 |
| jgriffith | sbezverk: interesting... try running the cmd manually if you can? | 18:55 |
| sbezverk | I am connecting to cinder-volume container and run vgs command and I DO SEE that VG | 18:56 |
| *** e0ne has quit IRC | 18:56 | |
| eharney | what creates the VG? maybe there's a race between it being created and c-vol starting at first? | 18:56 |
| jgriffith | sbezverk: so vgs --noheadings -o name cinder-volumes works just fine? | 18:56 |
| sbezverk | VG was created in advance | 18:56 |
| jgriffith | odd | 18:56 |
| sbezverk | VG never gets created by openstack | 18:56 |
| sbezverk | it is requirement for setup | 18:57 |
| jgriffith | sbezverk: sure | 18:57 |
| jgriffith | sbezverk: unless you use thin :) | 18:57 |
| jgriffith | sbezverk: then there's a special case there :) | 18:57 |
| jgriffith | sbezverk: but anyway.... | 18:57 |
| jgriffith | sbezverk: so if you run that command manually do you get the warning message? | 18:57 |
| sbezverk | jgriffith: if you want I can show you via webex | 18:57 |
| *** e0ne has joined #openstack-cinder | 18:57 | |
| jgriffith | sbezverk: sure | 18:57 |
| sbezverk | yes only if I use rootwrap | 18:58 |
| sbezverk | jgriffith: if I run this command as is | 18:58 |
| jgriffith | sbezverk: the problem here is that if you look at your first trace log: http://paste.openstack.org/show/566086/ notice it didn't return anything in output | 18:58 |
| jgriffith | sbezverk: which we then interpret as "DNE" | 18:58 |
| *** dustins has joined #openstack-cinder | 18:58 | |
| sbezverk | I do not get warning | 18:58 |
| jgriffith | sbezverk: hmm | 18:58 |
| eharney | you will only get the fd leak warning if you run it as a child process of kolla, which is what leaked the fd | 18:58 |
| sbezverk | it is there I can guarantee you | 18:59 |
| jgriffith | eharney: derp | 18:59 |
| jgriffith | sbezverk: oh, I believe you | 18:59 |
| sbezverk | I suspect your logging does not expect to see second line | 18:59 |
| jgriffith | sbezverk: quite possible | 18:59 |

| jgriffith | eharney: do you know of the correct way to just add that env var to /etc/lvm/lvm.conf for a quick sanity check? | 19:45 |
| *** lpetrut has quit IRC | 19:45 | |
| jgriffith | eharney: so adding that in the code means updating rootwrap and rebuilding all the kube images | 19:45 |
| eharney | jgriffith: not sure if lvm supports a way to set it there :/ | 19:46 |
| jgriffith | eharney: sigh | 19:46 |

| jgriffith | eharney: I'd need to update all the rootwrap entries that have LC-ALL=C in them no? | 19:48 |
| eharney | jgriffith: probably so | 19:49 |
| jgriffith | eharney: just unclear on like qemu-img cmd and such | 19:50 |
| jgriffith | but those I believe are just for the calls in to brick/lvm | 19:50 |
| eharney | jgriffith: it should be only the commands that use EnvFilter now | 19:50 |
| eharney | jgriffith: and not the qemu-img EnvFilter | 19:50 |
| jgriffith | eharney: so I'm trying to come up with an easy one line s/replace :) | 19:51 |
| jgriffith | but I don't think that's going to work out for me | 19:51 |
| jgriffith | eharney: actually... | 19:51 |
| jgriffith | eharney: just the LVM related show commands: section should be good | 19:51 |
| jgriffith | I think | 19:51 |
| jgriffith | eharney: oh.. hey.. lvm.conf log silent=0 --> silent=1 | 19:53 |
| jgriffith | bet that gets me what I want | 19:53 |
| *** alonma has joined #openstack-cinder | 19:53 | |

| patrickeast | erlon: yea i think thats ok for now, but i'd like to see if we can maybe share the code that does the thin calculations in a helper method between the scheduler capacity_filter and volume manager | 20:00 |
| patrickeast | erlon: we've had bugs in the past where we've needed to tweak them, and i'm concerned we will have more in the future and get those out of sync | 20:01 |
| sbezverk | jgriffith: trying lvm silent=1 | 20:02 |
| jgriffith | sbezverk: so I'm running with that rootwrap change locally and it's working | 20:03 |
| jgriffith | sbezverk: so seems we just aren't getting it configured correctly somehow | 20:03 |
| jgriffith | sbezverk: on the container that is | 20:04 |

| sbezverk | :-) | 20:08 |
| jgriffith | sbezverk: nice work! | 20:08 |
| jgriffith | sbezverk: now.... document exactly what I need to do to deploy that exact thing on my side please ;) | 20:08 |
| sbezverk | jgriffith: changing lvm.conf is not a solution | 20:08 |
| sbezverk | it will not be accepted by community | 20:09 |
| jgriffith | sbezverk: that's ok, we just need to figure out why your rootwrap didn't update... or build a new image with the update in it | 20:09 |
| sbezverk | we need to make rootwrap working | 20:09 |
| sbezverk | jgriffith: ok | 20:09 |
| jgriffith | sbezverk: I tested it on my side and it's working, so my only guess is that it's something off int he build steps maybe? | 20:09 |
| jgriffith | sbezverk: I also need to figure out some way to get to the bottom of why that message was causing a failure in the first place :( | 20:10 |
| cFouts | jgriffith, hemna: we've had some CI tests fail with an attempt in Cinder to perform an iscsiadm rescan on a node that Nova just deleted. Haven't seen it in about a week and was wondering if you knew if it was something that had been fixed recently. | 20:10 |
| jgriffith | cFouts: sadly I don't. I've had some really erradic behavior against my CI the past week | 20:10 |
| sbezverk | jgriffith: are you saying that command worked on your system without any rootwrap fle modification? | 20:11 |
| cFouts | jgriffith: okay, thanks. I'll keep investigating :) | 20:11 |
| jgriffith | sbezverk: no, I'm saying i updated the cmd and updated my volume.filters, restarted with success | 20:11 |
| jgriffith | sbezverk: also verified it by removing the rootwrap mod | 20:11 |
| jgriffith | sbezverk: when gerrit is back online I'll submit a patch for it | 20:11 |
| sbezverk | jgriffith: can you give me the diff then chaging volume filters | 20:12 |
| smcginnis | jgriffith: Looks like it's back. | 20:12 |
| jgriffith | sbezverk: yes | 20:12 |
| jgriffith | smcginnis: oh... damn, I didn't leave the building early enough :) | 20:12 |
| smcginnis | But a warning in infra that it's reindexing and could be slow. | 20:12 |
| smcginnis | I don't know if "slow" is any noticeable difference. ;) | 20:12 |
| smcginnis | jgriffith: Yeah, me too. | 20:12 |
| smcginnis | But that's not going to stop me from leaving soon. :) | 20:12 |
