BlackDexHello there12:10
BlackDexThe QoS *iops* options seem to be "static"12:10
BlackDexif i change them they won't apply runtime.12:10
BlackDexI need to re-attach a volume for this to work, or shutdown/poweron the instance12:11
BlackDexos there a way to set this during runtime?12:12
jungleboyjBlackDex: Correct. Those are set in the volume at creation time.12:12
jungleboyjSorry, at attach time.12:12
jungleboyjIt is set in libvirt.  Not aware of a way to make that dynamic.12:13
BlackDexoke12:14
BlackDexgood to know :)12:14
BlackDexthx jungleboyj12:15
jungleboyjBlackDex:  Welcome.  If it is like other functions in that area, making that dynamic would be very difficult.12:16
BlackDexfor that i think kvm/libvirt need some changes12:16
jungleboyjBlackDex:  Correct.12:17
BlackDexthe only way for it to be dynamic i think is if the backend supports it12:17
jungleboyjBlackDex:  Correct.  That would be another way to tackle it.12:17

kaisersHoi! Quick Q: I want to change some default settings for a Cinder driver. Am i correct that i a) add a deprecation note to the next release and b) change the behaviour with a new note in the release following after the next. Is that the way to go?12:33
jungleboyjkaisers: Hey there.12:34
smcginniskaisers: Changing a config option completely? Or just changing its default value.12:35
kaiserssmcginnis: default value only12:35
jungleboyjsmcginnis:  That was what I was about to ask.12:36
smcginniskaisers: Then you can do it in one release. You can change the default value and have a release note under the Upgrade section that calls out that the value has changed and when upgrading the deployer will need to modify it if they wish to keep the old value.12:36
jungleboyjShouldn't be so complicated for just changing the default value.12:36
jungleboyjsmcginnis:  ++12:36

smcginnisBaaah! Just realized the scaleio zero padding config option was just added during Rocky.18:30
smcginnisSo the whole multi-patch to avoid backporting deprecations was a waste of time.18:30

openstackgerritMerged openstack/cinder stable/pike: NetApp ONTAP: Fix driver force detach operations  https://review.openstack.org/59276922:38
mriedemit looks to me like force_host_copy doesn't do anything in a volume migration, only retype?22:41
mriedemhttps://docs.openstack.org/cinder/latest/contributor/migration.html22:47
mriedem" Enables or disables generic host-based force-migration, which bypasses the driver optimization." ?22:47
mriedemso if force_host_copy=False, it goes through the driver to do the migration, else it does a generic migration not using the volume driver22:48
mriedemwhat's the difference? the driver can optimize for the backend?22:48
