gusThe bit that confuses me is that I can't see anything that catches that error and tries some different strategy - and afaics scsi_id isn't installed in this devstack (or at least, it's installed in /lib/udev/scsi_id, which isn't in PATH)05:47
gusConfused how this usually passes dsvm integration tests :/05:47

*** esker has joined #openstack-cinder12:28
yglcan some one help me  with an issue12:28
dulekygl: Just describe your issue - maybe it will ring a bell for someone.12:29
ygldulek: in general when we launch an instance using a flavor, where will the hard disk for the VM be created ?12:29
ygldulek: is it on hypervisor host  ?12:30
dulekygl: Well, it depends. Ephemeral disk will be placed on the hypervisor host.12:30
dulekygl: If you're booting from a cinder volume then it depends on the cinder backend you're using.12:31
dulekygl: In the default on (LVM) volume can be placed anywhere and be attached to VM using iSCSI.12:31
ygldulek: but even in the cinder volume case, where will the hard disk required for the VM according its flavor  be created ?12:31
dulekygl: I don't think you can require a *Cinder* volume through flavor.12:32
ygldulek: I am really confused now12:32
geguileodulek: Thanks for the info :-)12:33
ygldulek: in general say i am booting a VM through glance image without a bootable volume, where will the hard disk required for the VM be created ?12:33
ygldulek: is it on the local hypervisor host ?12:34
dulekygl: Yeah, by default image will be copied to the compute node and an ephemeral disk will be created there.12:34
dulekygl: But if you're using Ceph for example, then it may be stored in Ceph.12:34
ygldulek: now second scenario: i am using a bootable volume by cinder. in this case the VM gets its image from the volume. But where is the hard disk required by its flavor created ?12:35
*** avishay has quit IRC12:35
ygldulek: is it on hypervisor still ?12:35
dulekygl: Yes, it will be on hypervisor.12:36
dulekygl: I'm trying to find nova.conf option specifying that exactly…12:36
ygldulek: so if I want to use external storage other than hypervisor for the hard disk of a VM ,  where should I mention this ?12:37
openstackgerritVictor Stinner proposed openstack/cinder: Port netapp dataontap driver to Python 3  https://review.openstack.org/28033112:38
dulekygl: You should create a volume in Cinder and attach it to a VM or boot a VM from it.12:38
dulekygl: Or you can use boot from volume - to make Nova create Cinder volume.12:39
*** cdelatte has quit IRC12:39
ygldulek:i know the boot frmo volume scenario12:39

*** sgotliv has joined #openstack-cinder12:39
*** salv-orlando has joined #openstack-cinder12:40
ygldulek: so if you are going to attach an empty volume to a vm, does that mean it doesn't require a hard disk in its flavor in first place ?12:40
*** raildo is now known as raildo-afk12:40

haypogeguileo: hi. too bad, you approved https://review.openstack.org/#/c/280331/ but https://review.openstack.org/#/c/278420/ was merged meanwhile and this second change adds new tests which fail on py3 :)12:41
haypogeguileo: well, i updated my patch to port new tests too12:41
dulekygl: Read descriptions of flavor parameters in the docs: http://docs.openstack.org/openstack-ops/content/flavors.html12:41
dulekygl: This will probably explain it best.12:42
ygldulek: ok12:42
geguileohaypo: lol12:43
*** markvoelker has joined #openstack-cinder12:43
haypogeguileo: hopefully, in 3 commits, we will be able to remove the whitelist of tests passing on py3 to run *all* unit tests12:43

openstackgerritWilson Liu proposed openstack/cinder: Huawei: Code cleanup  https://review.openstack.org/28293812:45
haypogeguileo: as i wrote before, my patches are ready, they are just blocked by an issue on the EMC VNC CI which doesn't want to recheck my change https://review.openstack.org/#/c/280241/ -- the previous run failed on a git clone..12:45

*** raildo-afk is now known as raildo12:46
dulekygl: If you're booting the instance from Cinder volume I think it will attach Cinder volume instead of root disk.12:46
ygldulek: ok12:46
ygldulek: ephemeral disk is like secondary storage right ?12:46
dulekygl: Yeah, I think so.12:47

*** markvoelker has quit IRC12:47

*** fernnest_ has quit IRC18:43
scottdadiablo_rojo: Because Nova 1) set's volume to attaching/detaching 2) does NOva stuf 3) does cinder stuff 4) sets volume to attached/available18:43
scottdadiablo_rojo: so if you restart Nova, volume be stuck in attaching or detaching. Amongst other possible problems.18:44

johnthetubaguyits probably broken today, but it shouldn't be18:45
scottdajohnthetubaguy: Yes. I'm not sure the fix is simple, however, because it is Nova that is managing the Cinder volume state.18:45
johnthetubaguyPS, a graceful shutdown of nova-compute should also avoid such problems, if you need to do a planned restat18:45
johnthetubaguyscottda: agreed, but we have fixed operations like snapshot and create instance to gracefully recover18:45

*** garthb_ has joined #openstack-cinder18:52
*** garthb has quit IRC18:52
scottdajohnthetubaguy: That looks good to clean this up in Nova __init__, but unfortunately we'd need a new API to call Cinder to 'force-detach' a volume that might be in the middle of an attach or detach. This would not only set the correct Cinder DB state but also terminate_connection and detach().18:55

scottdajohnthetubaguy: Yup. Operators definately want a way to cleanup stuck volumes. And it could also be used for Nova init cleanup. And could be used in a 'nova force-detach' , but that feature got stalled.19:03
johnthetubaguyyeah, I think this is a better way of looking at that feature actually19:03
johnthetubaguywork out a way to fix up failures after a nova-restart, rather than worrying about the fix up API, that can come second, if its still needed19:04

hemnaso, I think the proposal kinda sux19:30
hemnadunno19:31
smcginnisYeah, no ideal solution I guess.19:31
hemna"The idea would be to split the events. The first event would be for upstream technical contributors to OpenStack. It would be held in a simpler, scaled-back setting that would let all OpenStack project teams meet in separate rooms, but in a co-located event that would make it easy to have ad-hoc cross-project discussions. It would happen closer to the centers of mass of contributors, in less-expensive locations. "19:31
hemnaI'm not sure how that's even possible.19:31
*** martyturner has joined #openstack-cinder19:32

eharneyEmilienM: my guess is that it depends on the timing for rbd deleting the snapshot in the background, and there's a lot of differences in these two jobs as far as CentOS vs Ubuntu, maybe the versions of Ceph involved, etc22:43

jgriffithaorourke: ping22:54
aorourkejgriffith, hey22:54
jgriffithaorourke: yo22:54
jgriffithaorourke: hey... looks like your driver has a signature that's different maybe?22:55
jgriffithaorourke: is your code on github?22:55
jgriffithaorourke: of course I'm assuming you're using *your* driver :)22:55
jgriffithaorourke: in other words, it looks like the driver you have configured and are calling implements that method with a signature different than the reference?22:56
aorourkejgriffith, which method?22:56
*** jordanP has quit IRC22:57
aorourkejgriffith, the API call i commented about?22:57
jgriffithaorourke: list_replication_targets22:57
aorourkeah ok22:57
*** jgregor has quit IRC22:57
jgriffithaorourke: so if you look in manager.py and in the reference driver.py they match... which makes me think the driver you have configured is implementing the old method or something different?22:58

aorourkejgriffith, my patch is here https://review.openstack.org/#/c/279307/7/cinder/volume/drivers/hpe/hpe_3par_common.py looks like i am still expecting context22:59
jgriffithaorourke: you don't still have this do you:  "def list_replication_targets(self, context, volume)"22:59
jgriffithaorourke: ahh, yup.... so if you remove context in your driver you should be good to go23:00
aorourkejgriffith, def list_replication_targets(self, context)23:00
jgriffithaorourke: I don't know if there's a need to have context or not, we could certainly add it back in later if needed23:00
jgriffithaorourke: or if people want it now, I can do one more push :)23:00

aorourkejgriffith, question for you, do these API calls for for you when you call them? Even after restarting all cinder services i get this: "RPCVersionCapError: Requested message version, 1.39 is incompatible.  It needs to be equal in major version and less than or equal in minor version as the specified version cap 1.37."23:12
