| Rodrigo_BR | Live Migration failure: Unsafe migration: Migration may lead to data corruption if disks use cache != none | 00:33 |
|---|---|---|
| Rodrigo_BR | Can I perform live migration using NFS backend ? | 00:34 |
| haukebruno | Rodrigo_BR, in general yes. | 00:35 |
| Rodrigo_BR | <haukebruno> But I recive this error: Live Migration failure: Unsafe migration: Migration may lead to data corruption if disks use cache != none | 00:36 |
| haukebruno | Rodrigo_BR, but not sure about that cache thing. you could read that issue 'a lot' these days, also in ask.openstack.org | 00:37 |
| haukebruno | Rodrigo_BR, are you using nfsv3 or v4? we had some trouble using v4 so far and switched back to v3 | 00:38 |
| Rodrigo_BR | <haukebruno> I am using nfsv3 with the netapp driver | 00:39 |
| *** qeelee has joined #openstack-nova | 00:39 | |
| *** angdraug has quit IRC | 00:40 | |
| haukebruno | Rodrigo_BR, did you set any cache related options in your config files? we are using netapp too, but not with the specifig driver so far just mounting nfs on every compute node | 00:40 |
| Rodrigo_BR | <haukebruno> I posted in https://ask.openstack.org/en/question/89302/migration-operation-has-aborted/ | 00:40 |
| Rodrigo_BR | <haukebruno> nfs_mount_options=rw,bg,hard,nointr,tcp,vers=3,timeo=600,rsize=32768,wsize=32768,actimeo=0,sec=sys | 00:41 |
| *** ljxiash has joined #openstack-nova | 00:42 | |
| haukebruno | Rodrigo_BR, are you using nfs too for /var/lib/nova/instances? | 00:42 |
| Rodrigo_BR | <haukebruno> Yes ! I am | 00:43 |
| *** pwnall has quit IRC | 00:43 | |
| haukebruno | Rodrigo_BR, sorry, no clue here. you could try block migration as a workaround, but in general live migration should work, especially with an underlying netapp NFS export (we are doing it without problems) | 00:44 |
| Rodrigo_BR | <haukebruno> Ok ! thank you for help me | 00:45 |

| mriedem | sdague: do you plan on using the use_neutron option to also remove the security group driver option? | 14:50 |
| PaulMurray | sdague, do you know what happens with tempest re freeze - we have some LM tests to add and I want to understand deadlines | 14:50 |
| sdague | mriedem: yeh, I think that's the direction we should go | 14:50 |
| sdague | so that in newton we deprecate the security group option and key it off of this | 14:50 |
| sdague | so there is just 1 flag | 14:51 |
| mriedem | yeah, works for me | 14:51 |
| sdague | because that's almost even user friendly | 14:51 |
| *** atuvenie_ has quit IRC | 14:51 | |
| sdague | PaulMurray: because tempest is branchless, there isn't really a freeze in the same way | 14:52 |
| sdague | but I'd try to get them sorted in the next couple of weeks | 14:52 |
| PaulMurray | sdague, I think they try to get some kind of stability coming up to a release don't they (not that tempest isn't always stable of course) | 14:53 |
| sdague | honestly, I'm only lightly involved in tempest at this point, I'd ask mtreinish directly | 14:53 |
| PaulMurray | sdague, yeah, I guess I'm surrounded by tempest people, so I can ask them | 14:54 |
| mriedem | BobBall_AWOL: xenproject ci is off the rails it looks like | 14:55 |
| mriedem | hitting novalid host | 14:55 |
| mriedem | would be super sweet if the xen ci had the log formatting such that we can filter by log level | 14:55 |

| mriedem | BobBall_AWOL: sdague: oh i think the xenproject ci failure is just the libxenlight bug that has been around for a looong time | 14:57 |
| *** diogogmt has joined #openstack-nova | 14:57 | |
| mriedem | sdague: i would have asked jaypipes about https://review.openstack.org/#/c/288421/ | 14:59 |

| openstackgerrit | OpenStack Proposal Bot proposed openstack/nova: Updated from global requirements https://review.openstack.org/288357 | 14:59 |

| mriedem | ok | 15:02 |
| PaulMurray | mriedem, that stuff is deprecated - I'm going to remove it in the next cycle | 15:02 |

| PaulMurray | danpb, tdurakov I think the migration monitor gets lost if nova compute is restarted | 15:04 |
| sdague | mriedem: I asked bauwser about https://review.openstack.org/#/c/288421/ and he said it was unused | 15:04 |
| sdague | and legacy | 15:04 |
| danpb | PaulMurray: so don't do that then :-) | 15:04 |
| PaulMurray | danpb, tdurakov if force complete and pause are put done by that thread they will not be done if restarted | 15:04 |
| mriedem | libvirtError: internal error: libxenlight failed to create new domain 'instance-0000003c' | 15:04 |
| PaulMurray | danpb, I wonder if there is a way to restart monitors on restart? | 15:04 |
| mriedem | that should be a priority for the xen project ci to fix | 15:04 |
| ndipanov | PaulMurray, a gentle reminder https://review.openstack.org/244489 | 15:04 |
| danpb | PaulMurray: sure, it could be done...mere matter of coding | 15:05 |
| mriedem | sdague: yeah, i was thinking of the cpu monitor stuff | 15:05 |
| mriedem | *confused cpu monitor with compute stats | 15:05 |
| bauwser | PaulMurray: heard anything about live-migrate loosing neutron floating-ip connection ? | 15:05 |
| bauwser | mriedem: the monitors are in use | 15:05 |
| PaulMurray | danpb, I think what you proposed is a very good idea but may be better to make the monitor recover from restart | 15:06 |
| PaulMurray | first | 15:06 |
| PaulMurray | bauwser, yes | 15:06 |
| mriedem | bauwser: there is a series for that with dvr | 15:06 |
| PaulMurray | bauwser, I think - depends - are you thinking of somethign specific | 15:06 |
| mriedem | bauwser: PaulMurray: starts here https://review.openstack.org/#/c/260738/ | 15:06 |
| mriedem | johnthetubaguy: the xenproject ci still has a pretty high failure rate on this bug https://bugs.launchpad.net/nova/+bug/1461642 | 15:08 |
| openstack | Launchpad bug 1461642 in OpenStack Compute (nova) "libvirt-xen: Race between nova and a Xen script for updating the iptables" [High,In progress] - Assigned to Anthony PERARD (anthony-perard) | 15:08 |
| openstackgerrit | Pavlo Shchelokovskyy proposed openstack/nova: Fix config generation for Neutron auth options https://review.openstack.org/288513 | 15:08 |
| mriedem | johnthetubaguy: any idea if anthony perard is still working on that since there was a partial fix | 15:08 |
| mtreinish | PaulMurray: sdague is correct, there isn't really a freeze on tempest like on the other projects. So you can submit changes or new tests whenever | 15:09 |
| PaulMurray | mtreinish, thanks | 15:09 |
| mtreinish | this is partly because activity on the qa projects normally spikes during the FF window | 15:09 |
| johnthetubaguy | mriedem: I thought anthonyper said he was hoping to look at that, not sure if BobBall_AWOL has any more info on that. | 15:09 |
| mriedem | there were a couple of fixes | 15:09 |
| mriedem | but it's apparently still a problem | 15:10 |
| *** markvoelker has quit IRC | 15:10 | |

| johnthetubaguy | yeah, I think he mentioned something about looking into that at FOSDEM when I last saw him, not sure how thats been going | 15:10 |
| tdurakov | PaulMurray, restart of compute during live-migration will produce lot's of problems anyway, not sure is it really critical right now? | 15:11 |
| doffm | sdague: Any chance you could take another look at? https://review.openstack.org/#/c/224216/ You were -1 only for needing rebase. | 15:11 |
| *** claudiub has joined #openstack-nova | 15:12 | |
| PaulMurray | bauwser, the connection loss I know about (related to that neutron patch) is because DVR has to setup the dest host - at the moment this id done post migration when ports are rebound, which means some network traffic is lost and disrupts the connections | 15:12 |
| sdague | doffm: I'll just 0 out my review, still working through a thing on the use_neutron option | 15:12 |
| doffm | sdague: Thanks. | 15:12 |
| PaulMurray | bauwser, we discussed it at the mid-cycle with carl_baldwin and armax | 15:14 |

| figleaf | mriedem: yeah, the original idea was OpenStack was the basic plumbing, and each deployment could customize it to their heart's content | 16:57 |

| leakypipes | mriedem: no, I don't see the correlation there. | 16:58 |

| cdent | figleaf: do you have a history or references on when/where the interop thing entered the pic? | 17:01 |
| leakypipes | mriedem, cdent: I think that companies should build products *on top of* OpenStack, and those companies should contribute to making OpenStack services/tools as stable and rock-solid and singlular-focused as possible. I am anti- the inclusion of monolithic applications into the big tent (this includes Tacker, Murano, Fuel BTW) and would prefer to see a big tent of small-focused, stable, well-maintained tools that provide cloud management services | 17:01 |

| leakypipes | mriedem, cdent: I also believe that *if* an OpenStack service exposes a REST API, that that REST API should be curated by a single team to ensure no overlap with other OpenStack REST API endpoints.

| *** anush has quit IRC | 20:02 | |
| ansiwen | because it doesn't print the ERROR | 20:02 |

| mriedem | https://review.openstack.org/#/c/288639/2/novaclient/exceptions.py is new... | 20:03 |

| mriedem | https://github.com/openstack/python-novaclient/blob/master/novaclient/shell.py#L1083 | 20:07 |
| ansiwen | mriedem: yes, you are right | 20:08 |
| mriedem | so why add a new type of exception is my question | 20:09 |
| mriedem | just use CommandError | 20:09 |
| *** Marga_ has joined #openstack-nova | 20:10 | |
| ansiwen | mriedem: I grepped for "except.*CommandError" and found the file basecommand.py which handles it, and prints an ERROR in front of the message. BadCommand did the same without error. but now I realized, it was a file from pip in the .tox venv (>_<) | 20:10 |
| ansiwen | mriedem: so, there is no reason to add another exception | 20:11 |

| *** ctrath has quit IRC | 20:15 | |
| *** derekh has quit IRC | 20:18 | |
| ansiwen | mriedem: so, I could add the handler for BadCommand to get rid of the misleading ERROR... if I just change the message from "ERROR: Failed to get access list for public flavor type." to "ERROR: Access list not available for public flavors." there is not mich difference, WDYT? | 20:20 |
| mriedem | ansiwen: which lib is basecommand in? | 20:22 |
| *** ctrath has joined #openstack-nova | 20:22 | |
| ansiwen | mriedem: in pip itself. forget it. it was my mistake. | 20:22 |
| ansiwen | mriedem: my grep command found it by accident, because it was in the .tox directory, and I didn't pay attention | 20:23 |
| *** rfolco has quit IRC | 20:23 | |
| *** rfolco has joined #openstack-nova | 20:24 | |
| mriedem | ansiwen: so to clarify, the handler for CommandError is in some other library that isn't python-novaclient? | 20:24 |
| ansiwen | mriedem: yes, it's a completely different handler for an exception that happens to also be named "CommandError" | 20:25 |
| mriedem | so by adding a handler, you mean in the nova shell code https://github.com/openstack/python-novaclient/blob/master/novaclient/shell.py#L1083 to handle BadCommand and do the same as Exception but not prefix the message with ERROR? | 20:26 |
| ansiwen | exactly | 20:26 |

| *** pushkaru has joined #openstack-nova | 20:30 | |
| mriedem | maybe i'll return the favor to superdan and ask for his opinion | 20:31 |
| cfriesen_ | mriedem: The idea behind https://review.openstack.org/288109 seems reasonable to me. But if we're rebuilding on the same host we won't be able to tell if it's shared storage so it'll always keep it around. | 20:31 |
| ansiwen | well, I also don't care too much about such a sub-low-prio thing. I just know there are users that find this ERROR irritating. | 20:32 |
| mriedem | s/users/support engineers that have to explain it's a usage error rather than a real failure/ | 20:32 |
| *** salv-orlando has quit IRC | 20:33 | |
| cfriesen_ | mriedem: I've asked lbeliveau to take a look at https://bugs.launchpad.net/nova/+bug/1551504 since it's more his area of expertise | 20:33 |

| *** salv-orlando has joined #openstack-nova | 20:33 | |
| superdan | mriedem: ansiwen you guys have beat this to death farther than I think is necessary, so I'm not sure it matters. Just changing the text so it's not very confusing seems fine to me, ERROR prefix or not | 20:33 |
| mriedem | cfriesen_: couldn't we just add a host check? (and instance.host != self.host)? | 20:33 |
| mriedem | superdan: i think it's probably a good topic for the TC or cross-project meeting | 20:34 |
| mriedem | the osc guys probably know what to do! | 20:34 |
| cfriesen_ | mriedem: yes, I think that'd work. but we'd end up deleting the disks in the case where we are actually on shared storage but happen to rebuild on the same host. | 20:34 |
| superdan | mriedem: barf | 20:34 |
| ansiwen | hehe | 20:34 |
| mriedem | cfriesen_: so.... | 20:35 |
| mriedem | what i'm hearing is, | 20:35 |
| mriedem | if you're using ceph, | 20:35 |
| mriedem | don't ever rebuild your instance | 20:35 |
| mriedem | while using neutron | 20:35 |
| mriedem | b/c if the vif plug fails, your disks are toast | 20:35 |
| *** zengine has quit IRC | 20:36 | |
| ansiwen | mriedem, superdan: well, if at least you guys have some fun it worth it spending my friday evening with something I found nt necessary in the first place... :-) | 20:36 |
| cfriesen_ | mriedem: lol. so with ceph we don't ever want to destroy the disks in this case. with non-ceph shared storage it's tricky since we want to preserve the disks if we're on shared storage, but we can't reliably tell if that's the case. | 20:36 |
| cfriesen_ | mriedem: but what you propose (with the host check) is better than what we have now | 20:37 |
| cfriesen_ | mriedem: why do we want to destroy the disks in the failure case? | 20:38 |
| cfriesen_ | mriedem: if _create_domain_and_network fails does it revert the instance.host back to the previous value? (or have we not stored the new host yet?) | 20:39 |

| mriedem | if you care about the ERROR prefix, feel free to handle it, i don't really care about that | 20:42 |

| auggy | thanks melwitt | 21:21 |
| *** smatzek has quit IRC | 21:21 | |

| *** rfolco has quit IRC | 21:32 | |

| * auggy can read, there was no gain | 21:35 | |

| *** penick has joined #openstack-nova | 21:38 | |
