15:03:53 <enriquetaso> One of them is incomplete, we are going to discuss the rest:
15:04:00 <rosmaita> o/
15:04:11 <enriquetaso> hey Brian :P
15:04:22 <enriquetaso> #topic rbd: snapshot can't be deleted/unmanaged if its source volume is deleted from backend
15:04:23 <enriquetaso> #link https://bugs.launchpad.net/cinder/+bug/1957073
15:04:23 <enriquetaso> There's already a fix proposed to master that looks right, so feel free to review it in your spare time:

15:04:57 <enriquetaso> eharney ^ we've discussed this bug yesterday
15:05:24 <enriquetaso> so, you might be interested in the fix proposed
15:05:47 <eharney> yeah we should review this one, i'll take a look
15:06:02 <enriquetaso> moving on
15:06:05 <enriquetaso> last bug:
15:06:14 <enriquetaso> #topic LVM backed ISCSI device not reporting the same size to nova
15:06:14 <enriquetaso> #link https://bugs.launchpad.net/cinder/+bug/1956887
15:06:14 <enriquetaso> Summary: The user creates a 20GB volume and nova shows 4 Terabyte. The VM disk size is bigger than the real disk size on the iscsi-backed lvm volume.
15:06:34 <enriquetaso> I just ask you if this is a well known issue related to os-brick because I think I heard this a while ago but I'm not sure.
15:07:09 <enriquetaso> I wonder if*
15:08:28 <enriquetaso> OK.. need to check old bugs but the bug looks legit
15:08:30 <geguileo> enriquetaso: that's probably one of those backends that increase in 4TB chunks
15:08:33 <geguileo> rofl
15:08:41 <enriquetaso> it's LVM
15:08:54 <geguileo> oh, missed that, sorry
15:09:01 <eharney> yeah, this probably needs some investigation
15:09:03 <geguileo> then that doesn't make any sense...
15:09:38 <enriquetaso> yes, it doesn't, looks crazy. OK, moving on
15:09:46 <enriquetaso> #topic open discussion
15:10:34 <enriquetaso> Feel free to share bugs here (if we have any)
15:12:34 <geguileo> the LVM one is kind of scary...
15:12:36 <sfernand> eharney: gouthamr if you guys have some time please take a look at Felipe's patch to address the online extend issue
15:12:37 <sfernand> https://review.opendev.org/c/openstack/cinder/+/739079
15:12:51 <rosmaita> geguileo: i agree
15:13:30 <rosmaita> but it sounds like although fdisk is reporting the wrong size, the vm isn't being allowed to write into the "extra" space?
15:14:33 <enriquetaso> rosmaita, i'm not sure about that from the bug description
15:17:31 <rosmaita> ok, and the significance of 20GB volume isn't clear either, whether it doesn't happen for <20G or whether the reporter only tried with 20G
15:19:33 <enriquetaso> Okay, I'll ask the reporter if  the vm isn't being allowed to write into the "extra" space. And if this happen for <20G or whether the reporter only tried with 20G
15:19:59 <rosmaita> enriquetaso: i guess read and write
15:20:15 <enriquetaso> sure
15:20:49 <geguileo> looks like it by the kernel log message mentioned
15:20:56 <enriquetaso> #action (enriquetaso): Ask  the reporter if  the vm isn't being allowed to read/write into the "extra" space. And if this happen for <20G or whether the reporter only tried with 20G
15:21:10 <rosmaita> geguileo: looks like it's *not* being allowed?
15:21:31 <rosmaita> (that was my reading, but i have only had one coffee this morning)
15:22:07 <geguileo> rosmaita: not sure where the failure is coming from
15:22:22 <geguileo> I assume the LIO end
15:25:30 <enriquetaso> mmh
15:26:13 <enriquetaso> What should I check with the reporter then?
15:31:25 <enriquetaso> we're running out of time
15:31:47 <enriquetaso> I'll left some question
15:32:01 <rosmaita> sorry, i was reading through the bug again
15:32:41 <enriquetaso> sure, don't worry, feel free to add question on the bug report or anything
