whoami-rajatsmcginnis: Hi, i noticed that there are two parameters for creating a volume from image (--image and --image-id), if we provide different values for both then it gives priority to image-id, in the code its written for the support backward compatibility, https://github.com/openstack/python-cinderclient/blob/master/cinderclient/v3/shell.py#L602 ,10:10
whoami-rajati wanted to know if its still the case or one parameter (--image-id) is redundant now?10:10

imacdonnsmcginnis jungleboyj: with the above in place, ZFSSA CI seems to work with USE_PYTHON3=True... but have to decide what to do for stable branches ... they (at least Pike+) kinda mostly pass CI today, even though it's devstack-stein with the old cinder branch15:37
jungleboyjimacdonn: That is good.15:40
jungleboyjWhy are you running devstack-stein instead of checking out the stable branch?15:40
*** vivsoni has quit IRC15:43
imacdonnBecause I have one box do this on, and going backwards is not easy15:43
imacdonnnewer devstack uses newer UCA, which has newer packages15:43
jungleboyjimacdonn:  Gotcha.  If I remember correctly we don't have a stable branch test requirement for 3rd Party CI, it is appreciated if you haven't it but not required.15:44
imacdonnjungleboyj: yeah, so I think it's good that it mostly works today ... so if we want to keep that, I either have to hack in switching between py2 and py3 based on cinder branch, or backport the above fix to all the stable branches15:45
jungleboyjsmcginnis:  Preferences on the above options?15:48
smcginnisimacdonn, jungleboyj: That looks like something reasonable to backport.15:48
smcginnisIf that makes it easier to run CI on stable, then I think it would be good to do.15:48
jungleboyjsmcginnis:  Yeah, looks low risk to me.15:48
imacdonnOK, cool, I'll plan on that then - thanks!15:49
*** gkadam has joined #openstack-cinder16:02
imacdonnjungleboyj smcginnis: BTW, whilst playing with CI yesterday, I noticed that the volume manage/unmanage tests were getting skipped .. it appears that that happens unless devstack's config has TEMPEST_VOLUME_MANAGE_VOLUME=True16:33
smcginnisHmm, I think that was added because most backends at the time it was added didn't support that feature yet.16:34
imacdonnand on setting that, I noticed that ZFSSA's manage/unmanage implementation is "all kinds of broken" .. so I guess I'll be looking into that "in my copious spare time" (although apparently no one is using it)16:34
smcginnisI haven't looked through to see if that has changed.16:34
smcginnisOh, wait, I remember why. Partly at least.16:35
smcginnisEven the backends that do support that, the identifier used to manage a volume will vary from backend to backend.16:35
smcginnisSo the tempest test was written to support what LVM uses, but that isn't the same as probably what ZFSSA uses. At least that is my guess.16:35
imacdonnMaybe that's why the tests broke16:35
smcginnisThis was also before "list manageable" was added.16:36
smcginnisSo now the test could probably list manageable volumes and from that get the identifier to use.16:36
* smcginnis runs out for an appointment16:37
imacdonnI'll probably ping you about that when I get to look closer16:37
imacdonnfor now, I'll "neglect" to set TEMPEST_VOLUME_MANAGE_VOLUME=True ;)16:38

hemna_multipathing can mean HA to some18:32
smcginnisDHE: And there are a lot of different storage options that are built to be highly available - https://docs.openstack.org/cinder/latest/drivers.html18:33
DHEif the iSCSI (?) host crashes, can my VMs recover without rebooting18:33
DHEdrbd was supposed to be both active/active and give multipath options (effectively) but their code is pretty bad18:33
hemna_DHE depends on the backend18:33
DHEI have a server with a lot of hard drives in it. I can install any (preferably) open source applications onto it currently running centos718:34
hemna_if you want an opensource solution for a storage backend, then ceph is probably your best bet18:35
DHElike I said, I tried the drbdmanage driver and it's given me data loss. I did my own implementation of a ZFS driver using iscsi and while it works it's not redundant nor do I know how to make it so18:35
DHEI've heard bad things about ceph, but usually in the context of their POSIX filesystem layer. is the block storage that much better?18:37
