Library releases for M-2 14:09:54 <whoami-rajat> release team will propose patches for libraries, probably os-brick, python-brick-cinderclient-ext etc for M-2 14:10:11 <whoami-rajat> PTL (me) and release liaision (jbernard) needs to look out for patches 14:10:19 <whoami-rajat> 2. Deliverable files for 2023.2 Bobcat 14:10:24 <whoami-rajat> #link https://opendev.org/openstack/releases/src/branch/master/deliverables/bobcat 14:10:36 <whoami-rajat> I checked the directory and we have files for all relevant cinder projects 14:10:41 <whoami-rajat> cinder: YES 14:10:41 <whoami-rajat> cinderlib: YES 14:10:41 <whoami-rajat> cinder-tempest-plugin: YES 14:10:41 <whoami-rajat> os-brick: YES 14:10:41 <whoami-rajat> python-cinderclient: YES 14:10:42 <whoami-rajat> python-brick-cinderclient-ext: YES 14:10:56 <whoami-rajat> let me know if i missed anything 14:11:02 <whoami-rajat> but looks like we are good on this as well 14:11:41 <whoami-rajat> 3. Volume and target Driver freeze 14:11:45 <whoami-rajat> #link https://etherpad.opendev.org/p/cinder-2023-2-bobcat-drivers 14:12:13 <whoami-rajat> we have another driver this cycle which was mentioned on the ML 14:12:26 <whoami-rajat> #link https://lists.openstack.org/pipermail/openstack-discuss/2023-July/034321.html 14:12:39 <whoami-rajat> the problem right now it's failing the zuul check as well as third party CI 14:13:02 <whoami-rajat> forgot to mention, it's the TOYOU NetStor driver 14:13:25 <whoami-rajat> the author has asked for reviews and an extension 14:13:34 <whoami-rajat> the deadline is tomorrow so I'm not really sure 14:13:47 <whoami-rajat> currently I am planning to provide 1 week extension to all drivers because of lack of reviews 14:14:18 <whoami-rajat> it would be better if we have some volunteers, let's say 2 people, that commit to reviewing a driver 14:15:58 <caiqilong> thanks, we will propose a new patch to fix the previous fails later. 14:16:35 <whoami-rajat> I have added a Reviewers section to the etherpad 14:16:39 <whoami-rajat> #link https://etherpad.opendev.org/p/cinder-2023-2-bobcat-drivers 14:16:51 <whoami-rajat> caiqilong, thanks! 14:18:00 <whoami-rajat> I have also added my name as a reviewer for all 3 drivers 14:19:09 <whoami-rajat> @cores, please add your name against a driver if you are willing to review it 14:19:24 <whoami-rajat> i see rosmaita added his name for Touyou driver, thanks! 14:20:02 <whoami-rajat> anyway, it can be done after the meeting 14:20:05 <rosmaita> i can try Yadro FC also, but would also be good to have someone better with FC take a look 14:20:38 <whoami-rajat> ++ i think any other core member should volunteer for it 14:20:46 <rosmaita> basically, any current driver maintainer who has an FC driver would be good (even if not core) 14:21:08 <eharney> IIRC, we were waiting on a CI solution for the Lustre driver? 14:21:27 <whoami-rajat> yes, i was thinking more in terms of merging the driver, but non-cores, feel free to review any driver! 14:21:44 <whoami-rajat> eharney, yes, AFAIK it isn't sorted out yet but will check again 14:21:51 <harsh> will try on the FC driver :) 14:22:08 <whoami-rajat> thanks harsh ! 14:24:35 <whoami-rajat> i don't see any Lustre CI being reported on the driver 14:24:53 <whoami-rajat> but i see a discussion towards the end comment that the author will work on it 14:25:08 <whoami-rajat> the bad thing is that comment is from April 19th 14:25:52 <whoami-rajat> let's target the Yadro FC Driver and TOYOU NetStor drivers for now 14:26:23 <whoami-rajat> i will send out a mail to ML about the extension of deadline by 1 week 14:27:38 <whoami-rajat> that's all i had for announcements 14:27:45 <whoami-rajat> let's move to topics 14:27:55 <whoami-rajat> #topic [Cinder-Backup] Spec to introduce a backup_status field for volumes and a split-up of the backup status away from the volume_status. 14:28:33 <whoami-rajat> crohmann, are you around? 14:29:02 <whoami-rajat> looks like he is not 14:29:18 <whoami-rajat> I think what we wanted to ask is, if there are any takers for this feature work 14:29:37 <whoami-rajat> he has committed to helping out with implementation but can't work on it as primary authors 14:30:21 <whoami-rajat> so reiterating it again, are there any takers for this feature work? 14:30:40 <whoami-rajat> s/authors/author 14:32:09 <crohmann> whoami-rajat: I am ... but only partially. 14:32:42 <whoami-rajat> ack 14:33:01 <whoami-rajat> looks like there aren't any takers in current meeting but we can revisit this again 14:34:05 <crohmann> too bad. What happens with this merged spec if there is nobody taking it? 14:35:06 <whoami-rajat> if someone would like to implement it, they have time till M-3 14:35:11 <whoami-rajat> else we can repropose the spec to next cycle 14:35:50 <whoami-rajat> s/to/in 14:37:55 <whoami-rajat> let's revisit this again 14:37:59 <whoami-rajat> and let's move to next topic 14:37:59 <crohmann> ok. That's really unfortunate. I thought this would be more of a project goal to implement this 14:38:39 <whoami-rajat> we need developer bandwidth to implement it which looks like we don't have as of now 14:38:51 <whoami-rajat> because of the same issue, one spec is postponed to next cycle 14:40:20 <whoami-rajat> ok, next topic 14:40:22 <whoami-rajat> #topic [Cinder-Backup] Performance issues with chunked driver 14:40:32 <whoami-rajat> it's again by crohmann 14:40:42 <whoami-rajat> since there is a nice summary on the etherpad 14:40:48 <whoami-rajat> I will paste the same info here 14:40:51 <zaitcev> "the etherpad"? 14:41:11 <whoami-rajat> the meeting etherpad 14:41:16 <whoami-rajat> #link https://etherpad.opendev.org/p/cinder-bobcat-meetings 14:41:39 <whoami-rajat> Jon Bernard from RedHat offered to look into the performance issues with chunkeddriver 14:41:41 <whoami-rajat> Unfortunatly we only exchanged a few emails so far. 14:41:42 <whoami-rajat> But I just watched the talk from Enrico Bocchi and Luis Fernandez Alvarez from Cern about their endevours with Cinder-Backup 14:41:52 <whoami-rajat> #link https://www.youtube.com/watch?v=ni-UgftgAy0 14:42:02 <whoami-rajat> Apparently they came to the same conclusion, that object storage backends are currently way to slow and not usable 14:42:02 <whoami-rajat> I certainly will try to contact them both if they would join any efforts to speed up the chunkeddriver. 14:42:02 <whoami-rajat> I just wanted to emphasize that this issue affects more people, even large installations such as at Cern, and forces them away from using object storage as cinder-backup backend. 14:43:20 <whoami-rajat> I think Jon is not around at this time 14:47:00 <zaitcev> OK. I'm not going to cross Jon on the performance then, or at least I'll ask how he's doing. 14:47:17 <zaitcev> I'll take a look at Christian's review 14:47:27 <whoami-rajat> cool 14:47:39 <crohmann> I did not want to point him out in any way ... I simply wanted to say, this really is an issue ... for big installations. 14:47:45 <crohmann> thx a ton zaitcev 14:47:48 <whoami-rajat> i think the idea is to get this addressed 14:51:08 <whoami-rajat> thanks crohmann for the update, maybe we can revisit if we have any progress on this 14:51:21 <whoami-rajat> any other thing to discuss on this? 14:52:34 <whoami-rajat> guess not 14:52:39 <whoami-rajat> let's move to open discussion 14:52:43 <whoami-rajat> #topic open discussion 14:55:49 <whoami-rajat> please take a look at the review request section 14:56:07 <whoami-rajat> some patches already have a +2 and requires a second vote 14:57:57 <whoami-rajat> Sofia is not around today so we will not have Bug squad meeting 15:00:42 <whoami-rajat> we are out of time 15:00:42 <whoami-rajat> thanks everyone for attending! 15:00:44 <whoami-rajat> #endmeeting
