| 10:24:10 | samuelkunkel[m] | (hope it is readable now) | |
| 10:25:18 | frickler | seem bauzas was the last one working on it | |
| 10:25:51 | samuelkunkel[m] | currently I will use the quick fix provided https://review.opendev.org/c/openstack/nova/+/838976 | |
| 10:26:43 | bauzas | frickler: yup, I need to update my change | |
| 10:26:53 | bauzas | it's a priority I have | |
| 10:38:36 | samuelkunkel[m] | that sounds nice, if you need somebody to test - feel free to reach out to me, have some nodes with mdevs to play on | |
| 11:56:41 | ygk_12345 | HI all | |
| 12:04:39 | sean-k-mooney | samuelkunkel[m]: we not only plan to fix that but backport the fix to wallaby as we require it for our downstream product that far and there is no point doing it downstream only since the fix is backpoartable | |
| 12:05:19 | sean-k-mooney | so given your on yoga that shoudl hopefully also adress your usecase | |
| 12:05:33 | samuelkunkel[m] | yes, that sounds great | |
| 12:05:48 | samuelkunkel[m] | I assume there is currently no estimation possible on a timeframe? | |
| 12:06:17 | sean-k-mooney | well the patch thats propsoed actully works we just need a few comments adressed | |
| 12:06:45 | auniyal | Hi sean-k-mooney | |
| 12:07:02 | sean-k-mooney | downstream we have a dealine of mid decemebr to adress this so i am stongly hoping that we can adress this upstream before then so our product team does not start asking me about it | |
| 12:07:11 | auniyal | how can we run tox functional locally in train branch | |
| 12:07:20 | auniyal | tox -e functional fails | |
| 12:07:27 | sean-k-mooney | use the python3 version | |
| 12:07:51 | sean-k-mooney | or a vm/container based on ubutu 18.04? | |
| 12:07:52 | samuelkunkel[m] | I can second that, it also works on my yoga setup on a non productive cluster. Thanks for the clarification. Until the fix is backported I just use the patch | |
| 12:07:56 | samuelkunkel[m] | thanks for all the information | |
| 12:09:00 | sean-k-mooney | auniyal: so on tain you can use tox -e functional-py36 or tox -e functional-py37 | |
| 12:10:37 | sean-k-mooney | auniyal: i would either use ubuntu 18.04/ubuntu-bionic or centos 8 stream to run the tests | |
| 12:11:14 | sean-k-mooney | we use 18.04 in teh ci https://github.com/openstack/nova/blob/stable/train/.zuul.yaml#L72-L119 | |
| 12:11:19 | auniyal | got same error, I think its trying to need some package/module | |
| 12:11:20 | auniyal | https://paste.opendev.org/show/bsE4F25vNPl8BaGh7I6I/ | |
| 12:11:45 | sean-k-mooney | you are trying to use 3.8 | |
| 12:12:24 | auniyal | oh in here - /usr/lib/python3.8/runpy.py | |
| 12:12:34 | sean-k-mooney | do you have 3.6 avaiable | |
| 12:12:53 | auniyal | no right now 3.6 | |
| 12:12:57 | auniyal | 3.8 | |
| 12:13:13 | sean-k-mooney | ya 3.8 was not released/supported by train | |
| 12:13:33 | auniyal | if I create venv of 3.6 and install test-requirements.txt in it | |
| 12:13:36 | auniyal | will it work | |
| 12:13:47 | sean-k-mooney | so if you want to run these you need to use an operating system that was support hence why i said centos 8 stream or ubuntu 18.04 | |
| 12:14:14 | auniyal | ack, will go with ubuntu 18, | |
| 12:14:23 | auniyal | thanks Sean | |
| 12:14:42 | sean-k-mooney | if you host os is too new thing liek sqlight might have issues | |
| 12:15:05 | sean-k-mooney | basically where we have python modules that wrap c libs | |
| 12:15:23 | sean-k-mooney | if your host os lib is too new then the old python bindign might now work | |
| 12:15:53 | sean-k-mooney | so if your currently using say the latest fedora you are likely to have issues with old releases like train | |
| 12:16:16 | sean-k-mooney | i generally use vms or contaienr to work around that if i hit that | |
| 12:16:54 | auniyal | yeah I am using vm , devstack on ubuntu 20 | |
| 12:17:31 | auniyal | fo this tests, will go with ubuntu 18 | |
| 12:17:57 | sean-k-mooney | ack i used to keep a few vms around for backporting | |
| 12:18:31 | sean-k-mooney | i do that less now just because its rare that i need older then 3.8 | |
| 12:19:42 | auniyal | ack | |
| 12:19:45 | sean-k-mooney | i think we added 3.8 in ussuri so train is really the only release that does not supprot 3.8 officall now | |
| 12:20:18 | sean-k-mooney | on it was victoria | |
| 12:21:22 | auniyal | for ussuri also I was dependent on zuul, but as there less conflict so it need less tests | |
| 12:23:53 | sean-k-mooney | frickler: by the way i have been using matrix on and off via the element client pretty seamlessly for irc | |
| 12:24:07 | sean-k-mooney | frickler: i still use weechat as my main irc client | |
| 12:24:48 | sean-k-mooney | but if im not at my work laptop i somethimes use teh eleemnt client form my personal laptop or ipad to chat via teh matrix.org bridge | |
| 12:25:44 | sean-k-mooney | so ya if you keep messanges relitivly short (3-4 lines) it works fine i havent hit the lenght limit personlly | |
| 12:26:10 | sean-k-mooney | of the irc alternivies i have used matrix is really the only one i tollerate | |
| 12:27:16 | sean-k-mooney | if the element desktop clinet ever get the ablity to sign into two matix accounts at once it might even be something i would consider as a replacemnt for weechat | |
| 12:27:22 | frickler | sean-k-mooney: there have also been issues where the bridge disconnects but you do not notice on the matrix side, so my personal suggest is still to not use this, ymmv | |
| 12:29:54 | sean-k-mooney | ya i have not had that issue but i still use irc as my primary interface and matix as what i use when im traveling or not working from my normal location | |
| 12:30:12 | sean-k-mooney | so i porably would not notice if there were tempoiry issues | |
| 12:33:36 | admin1 | i have a vm which is always in a pause state in the hypervisor .. trying to unpause using virsh gives error: Timed out during operation: cannot acquire state change lock (held by monitor=remoteDispatchDomainCreateWithFlags) .. the vm is backed by volume on ceph, but ceph is fine and there are no locks | |
| 12:33:45 | admin1 | what can i do to check/troubleshoot this issue | |
| 12:33:56 | admin1 | i rebooted the hypervisor as well, no luck | |
| 12:34:50 | sean-k-mooney | this might be a lock crated by qemu | |
| 12:35:06 | sean-k-mooney | have you tried stopping the vm and staring it | |
| 12:35:14 | sean-k-mooney | e.g. via a hard reboot | |
| 12:35:47 | admin1 | when i do a vrish destroy, it disappears from virsh list --all | |
| 12:36:06 | admin1 | when i start again (horizon/cli) appears back | |
| 12:36:09 | admin1 | with a paused state | |
| 12:36:55 | sean-k-mooney | ack | |
| 12:37:19 | sean-k-mooney | did you check the qemu instance log for any errors | |
| 12:37:35 | sean-k-mooney | this does not sound like a nova issue by the way | |
| 12:37:55 | sean-k-mooney | this sound like an issue at the qemu/libvirt level and or perhaps the ceph interaction | |
| 12:38:19 | sean-k-mooney | you dont happen to have a kvm error in the instance log do you? | |
| 12:38:59 | sean-k-mooney | we hit an issue with ubutu 22.04 where libvirt incorrectly detected the cpu model | |
| 12:39:11 | sean-k-mooney | it enabled amd cpu flags in the domain on an intel host | |
| 12:39:25 | sean-k-mooney | that left teh vm in a paused state | |
| 12:39:59 | sean-k-mooney | although that would not expaling the lock message but i woudl check the qemu instance log in anycase | |
| 12:40:13 | admin1 | sean-k-mooney thanks . i know what to check for now | |
| 12:40:51 | admin1 | where does qemu/libvirt read the ceph connectioon details like mon addresses ? | |
| 12:40:57 | admin1 | from /etc/ceph/ceph.conf ? | |
| 12:41:51 | admin1 | or is it internally somewhere else | |
| 12:43:43 | sean-k-mooney | we get them form the cinder attachment connection info and then store them in our db and pass it to libvirt | |
| 12:43:57 | sean-k-mooney | so no not from the ceph.conf | |
| 12:45:10 | sean-k-mooney | in recent release of openstack (xena+) we have a nova manage command to refresh the atachment info | |
| 12:45:12 | sean-k-mooney | https://docs.openstack.org/nova/latest/cli/nova-manage.html#volume-attachment-refresh | |
| 12:45:29 | admin1 | this one is not xena yet | |
| 12:45:40 | admin1 | i want to remove 2x mons and use only 1 remaining mon | |
| 12:45:46 | admin1 | how do I update/edit this db ? | |
| 12:46:00 | sean-k-mooney | with great pain and care | |
| 12:46:21 | sean-k-mooney | so we added this command to nova-manage because this is sotred in a json blob in the db | |
| 12:46:41 | sean-k-mooney | while it can be modifed its a pain to do | |
| 12:47:15 | sean-k-mooney | admin1: one option woudl be to grab a xena contaiern or create a xena virtual env and just run nova manage | |
| 12:47:58 | sean-k-mooney | i belive this is implemented such that if you have the new version of nova manage and point it to an old cloud it can work but im not 100% certin of that | |
| 12:48:00 | admin1 | you mean have binaries of xena but connect to existing db to manage/manipulate the entries ? | |
| 12:48:08 | sean-k-mooney | ya | |
| 12:48:24 | sean-k-mooney | so bauzas gibi correct me if im wrong be we have had customer do that right^ | |
| 12:48:57 | sean-k-mooney | use the updated contaienr with this command ot repair old dbs when connection infor is out of date | |
| 12:49:34 | sean-k-mooney | admin1: i think we have a downstream backport of this by the way to some release which is why im not 100% sure how we used this downstream with train | |
| 12:51:45 | sean-k-mooney | admin1: ya so we have it backported downstream to train in our 16.2 product | |
| 12:52:15 | sean-k-mooney | and i think we have had custoemr use the 16.2 contaienr to fix this on queens/osp 13 | |
| 12:52:19 | admin1 | i am on osa tag 23.1.2 | |
