15:01:54 <opendevmeet> The meeting name has been set to 'cinder_bs'
15:02:03 <enriquetaso> Hey, I just wanna say that there are a bunch of new bugs reported during my holiday, so I'm still processing them. Also, most of the 'incomplete' or 'waiting for more info bugs' were updated with info so I'm trying to check them as well..
15:02:14 <enriquetaso> I guess you'll receive the report email at the end of the day with all the bugs. I have one bug for today's meeting:
15:03:07 <rosmaita> o/
15:03:11 <whoami-rajat> hi
15:03:31 <enriquetaso> #topic [RBD] Amend the formula of retrieving total_capacity for a rbd pool
15:03:40 <enriquetaso> #link https://bugs.launchpad.net/cinder/+bug/1960206
15:03:40 <enriquetaso> I think this is a bug report for quotas so geguileo might be interesting.
15:03:53 <enriquetaso> Summary: The reporter points out that the value of the RBD total_capacity field is not being correctly calculated. Because it changes depending on the ceph version being used.
15:04:02 <yuval> sorry, cinder_bs stand for?
15:04:13 <rosmaita> cinder bug squad
15:04:25 <yuval> ok... not what I had in mind
15:04:29 <geguileo> lol
15:04:30 <rosmaita> :)
15:04:34 <yuval> lol
15:04:35 <geguileo> you though it was BS  ;-)
15:04:36 <enriquetaso> It's a short irc meeting to discuss the bug reported this week
15:04:44 <enriquetaso> bugs*
15:04:49 <rosmaita> yes, i was in a sophomoric mood when i proposed that name for the meeting
15:05:04 <yuval> :)
15:05:19 <yuval> first I thought it was just a joke
15:05:43 <yuval> sorry, please continue
15:05:58 <geguileo> enriquetaso: that has nothing to do with quotas  ;-)
15:06:10 <enriquetaso> Cool, my bad
15:06:14 <geguileo> that's how the RBD driver is calculating the stats of the backend to report to the scheduler
15:06:38 <enriquetaso> is it a problem that the calculation changes between ceph versions?
15:07:07 <enriquetaso> I should probably reproduce the bug first, i haven't
15:07:29 <enriquetaso> More info:
15:07:29 <enriquetaso> Currently, the value of free_capacity for a rbd pool is "max_avail" retrieved from the command 'ceph df -f json' when quota limit is not set for this pool. And in that scenario the value of total_capacity is the sum of free_capacity and 'bytes_used' also retrieved from the command 'ceph df -f json' in the case of dynamic total capacity.
15:07:37 <enriquetaso> However, there is a considerable difference for the command 'ceph df -f json' for different ceph versions. For example, the output of that command of the version 12.2.11 of ceph lacks 'STORED' field and the formula of its '%USED' filed is relevant to 'USED' field while the output of that command of the version 12.2.13 possesses 'STORED' field and the formula of its '%USED' filed is relevant to 'STORED' field.
15:07:44 <enriquetaso> Finally I think the LP needs a name change.
15:11:13 <enriquetaso> OK.. feel free to check out the bug if you have time. Moving on..
15:11:22 <enriquetaso> #topic open discussion
15:11:24 <rosmaita> ok, that bug doesn't look critical unless you are running close to capacity
15:11:50 <rosmaita> enriquetaso: nice to see you back, hope you had a good vacation
15:11:58 <enriquetaso> True.. I'll move it to 'low' and remove the quota tag
15:12:09 <enriquetaso> thanks rosmaita!
15:13:33 <enriquetaso> guess we don't have bugs for the open discussion
15:14:38 <enriquetaso> Thanks for today's meeting!
15:15:54 <rosmaita> thanks enriquetaso
