Issue resizing volumes attached to running volume backed instances
by Jérôme BECOT 09 Dec '22

09 Dec '22

Hello Openstack, We have Ussuri deployed on a few clouds, and they're all plugged to PureStorage Arrays. We allow users to only use volumes for their servers. It means that each server disk is a LUN attached over ISCSI (with multipath) on the compute node hosting the server. Everything works quite fine, but we have a weird issue when extending volumes attached to running instances. The guests notice the new disk size .. of the last extent. Say I have a server with a 10gb disk. I add 5gb. On the guest, still 10gb. I add another 5gb, and on the guest I get 15, and so on. I've turned the debug mode on and I could see no error in the log. Looking closer at the log I could catch the culprit: 2022-12-08 17:35:13.998 46195 DEBUG os_brick.initiator.linuxscsi [] Starting size: *76235669504* 2022-12-08 17:35:14.028 46195 DEBUG os_brick.initiator.linuxscsi [] volume size after scsi device rescan *80530636800* extend_volume 2022-12-08 17:35:14.035 46195 DEBUG os_brick.initiator.linuxscsi [] Volume device info = {'device': '/dev/disk/by-path/ip-1...1:3260-iscsi-iqn.2010-06.com.purestorage:flasharray.x-lun-10', 'host': '5', 'channel': '0', 'id': '0', 'lun': '10'} extend_volume 2022-12-08 17:35:14.348 46195 INFO os_brick.initiator.linuxscsi [] Find Multipath device file for volume WWN 3624... 2022-12-08 17:35:14.349 46195 DEBUG os_brick.initiator.linuxscsi [] Checking to see if /dev/disk/by-id/dm-uuid-mpath-3624.. exists yet. wait_for_path 2022-12-08 17:35:14.349 46195 DEBUG os_brick.initiator.linuxscsi [] /dev/disk/by-id/dm-uuid-mpath-3624... has shown up. wait_for_path 2022-12-08 17:35:14.382 46195 INFO os_brick.initiator.linuxscsi [] mpath(/dev/disk/by-id/dm-uuid-mpath-3624) *current size 76235669504* 2022-12-08 17:35:14.412 46195 INFO os_brick.initiator.linuxscsi [] mpath(/dev/disk/by-id/dm-uuid-mpath-3624) *new size 76235669504* 2022-12-08 17:35:14.413 46195 DEBUG oslo_concurrency.lockutils [] Lock "extend_volume" released by "os_brick.initiator.connectors.iscsi.ISCSIConnector.extend_volume" :: held 2.062s inner 2022-12-08 17:35:14.459 46195 DEBUG os_brick.initiator.connectors.iscsi [] <== extend_volume: return (2217ms) *76235669504* trace_logging_wrapper 2022-12-08 17:35:14.461 46195 DEBUG nova.virt.libvirt.volume.iscsi [] Extend iSCSI Volume /dev/dm-28; new_size=*76235669504* extend_volume 2022-12-08 17:35:14.462 46195 DEBUG nova.virt.libvirt.driver [] Resizing target device /dev/dm-28 to *76235669504* _resize_attached_volume The logs clearly shows that the rescan confirm the new size but when interrogating multipath, it does not. But requesting multipath few seconds after on the command line shows the new size as well. It explains the behaviour. I'm running Ubuntu 18.04 with multipath 0.7.4-2ubuntu3.2. The os-brick code for multipath is far more basic than the one in master branch. Maybe the multipath version installed is too recent for os-brick. Thanks for the help Jerome

[ironic][release] Bugfix branch status and cleanup w/r/t zuul-config-errors
by Jay Faulkner 08 Dec '22

08 Dec '22

Hey all, I've been looking into the various zuul config errors showing up for Ironic-program branches. Almost all of our old bugfix branches are in the list. Additionally, not properly retiring the bugfix branches leads to an ever-growing list of branches which makes it a lot more difficult, for contributors and operators alike, to tell which ones are currently supported. I've put together a document describing the situation as it is now, and my proposal: https://etherpad.opendev.org/p/IronicBugfixBranchCleanup Essentially, I think we need to: - identify bugfix branches to cleanup (I've done this in the above etherpad, but some of the ) - clean them up (the next step) - update Ironic policy to set a regular cadence for when to retire bugfix branches, and encode the process for doing so This means there are two overall questions to answer in this email: 1) Mechanically, what's the process for doing this? I don't believe the existing release tooling will be useful for this, but I'm not 100% sure. I've pulled (in the above etherpad and a local spreadsheet) the last SHA for each branch; so we should be able to EOL these branches similarly to how we EOL stable branches; except manually instead of with tooling. Who is going to do this work? (I'd prefer releases team continue to hold the keys to do this; but I understand if you don't want to take on this manual work). 2) What's the pattern for Ironic to adopt regarding these branches? We just need to write down the expected lifecycle and enforce it -- so we prevent being this deep into "branch debt" in the future. What do folks think? - Jay Faulkner

[ironic][stable] Cleanup of clerical issues in ironic-stable-maint group
by Jay Faulkner 08 Dec '22

08 Dec '22

Hey all, I was looking over Ironic ACLs in Gerrit today, and I discovered the ironic-stable-maint group which is set to include ironic-core and stable-maint-core (as expected) -- but I also discovered a member in this list who is no longer a core reviewer, or active contributor to Ironic (Jim Rollenhagen). Lucky for us, Jim is a nice guy and we all trust him, and this access hasn't been used. In order to prevent this from happening in the future, I've removed all individual members from the ironic-stable-maint group and left it inheriting from ironic-core. The effective difference is just that Jim has been removed. tl;dr: The effective ironic-stable-maint core group has been dropped by one; Jim Rollenhagen was mistakenly left in the list. Thanks, Jay Faulkner

[Horizon] How to enforce particular language on login
by A Tom 07 Dec '22

07 Dec '22

Hi everyone, I have a question regarding languages in Horizon - is there any way to enforce different language for different users - I mean without user interaction. Like user account is created and since then the default language for the user is set. Can it be done via Horizon API/config? Or maybe as Domain/Project properties? And second question - what about two different Horizons to one openstack? I mean every resorces are the same, but first Horizon has FQDN X-company.YY and is branded with X-company logo, and the other one has FQDN Y-company.ZZ and is branded wit Y-company logo - is such setup possible/right? OR maybe also two domains should be used? Best regards Adam Tomas

[mistral] Mistral maintenance and PTL
by Axel Vanzaghi 07 Dec '22

07 Dec '22

Hello everyone, Let me introduce myself, Axel Vanzaghi, first used OpenStack in 2015 and got back to it when I joined OVHCloud as SRE. Here at OVHCloud, we make an intensive use of Mistral in our internals processes, so we don't want to see it going deprecated [1] or abandonned. We decided to take action to maintain it, first by proposing someone to be the PTL for Mistral [2]. I proposed myself for this role. Yet, my experience with Mistral is only being an user of it, I worked on some of our workflow. However, I really liked what we could do with the tool so I'm willing to learn more and contribute on this project as I will be able to have time for it. Our first goal is to maintain the project alive, but new features will still be welcomed. Regards, Axel Vanzaghi [1] https://review.opendev.org/c/openstack/governance/+/866562 [2] https://lists.openstack.org/pipermail/openstack-discuss/2021-February/02015…
