kukaczhi, after changing qos limits in front-end type (libvirt-qemu) specification, is there a method for existing volumes to apply the new qos values?16:10
smcginniskukacz: I may be wrong, but I think those are only applied when the volume is attached.16:11
*** takamatsu has joined #openstack-cinder16:12
kukaczsmcginnis: thank you. that's perhaps a problem, as mostly I need to update it on root volumes. might there be some workaround by direct modifying the VM parameters on hypervisor?16:14
kukaczmust say that I have just tried that, but seems the new value is not in effect even after the operating system was restarted16:15
smcginniskukacz: Maybe. You probably should ask the nova folks about that. I'm not really sure if there is a way.16:15

openstackgerritGorka Eguileor proposed openstack/cinder master: Add cinderlib functional tests  https://review.openstack.org/62067116:18
kukaczsmcginnis: ok, I'll try. just one different question - I just barely remember there was some blueprint on detaching root volumes from instances. do you know if that got implemented? or should I also ask Nova guys?16:18
geguileoiirc we were not going to implement it16:18
geguileowe were going with a re-imagining path16:18
geguileowhich was a way to change the contents of the root volume16:19
geguileoat least that's the last thing I remember16:19
geguileokukacz: smcginnis ^16:19
smcginnisSo interally we will be detaching, but it's not an explicit detach to the user.16:19
smcginnisBut yes, that is something that still needs to be implemented.16:19
smcginnisI suppose that would pick up QoS changes, but at the cost of resetting your OS image back to its original state. :)16:20
jungleboyjgeguileo:  Right, that was the path we were going down but it hasn't been implemented.16:20
eharneylive updates of qos values for attached volumes was on down on my to-do list somewhere when i was working on qos more, it's something we could consider if needed16:20
smcginniseharney: Do you know if that is something that can be done at runtime?16:20
jungleboyjOtherwise, would it be possible to control this from the backend?  Guess it woul depend on your backend.16:21
kukaczjungleboyj: in this case it's RBD/Ceph, which does not have qos16:21
eharneysmcginnis: i think it is available for libvirt, but i may have just imagined that, it's been a while16:21
kukacztherefore I use front-end type16:21
jungleboyjkukacz: Ah.  Yeah, that won' thelp.16:21
kukaczeharney: did you have a procedure evaluated for that? I mean if that was a front-end method16:23
*** kukacz has quit IRC16:24
eharney"virsh blkdeviotune" is the method to adjust them16:25
*** kukacz has joined #openstack-cinder16:26
eharneyso the idea was to have cinder poke a nova event API etc when updates are needed, which could apply the updates via libvirt16:26
*** abishop_ has joined #openstack-cinder16:27
eharneysmcginnis: so yeah it does exist ^16:27
*** abishop_ has quit IRC16:27
smcginnisOK, cool.16:27
*** abishop has quit IRC16:29
kukaczseems that I've found a very strange manual workaround, which involves manual editing the VM definition on hypervisor and live-migrating it to another compute node16:34
kukacz... then the new qos came into effect16:34
kukaczsmcginnis, geguileo, eharney, jungleboyj: thanks for your inputs!16:36
smcginniskukacz: Glad you figured out a way.16:37
