geguileodid the first backup finish before you tried to do the incremental one?10:03
geguileoyou do a list of the backups and it must appear as available10:04
geguileothat's what the error message says10:04
shubham0dgeguileo:yes they are available.I have checked by cinder list10:05
geguileocinder list only list volumes, not backups10:05
geguileomessage talks about "parent backup", not source volume10:05
shubham0dgeguileo:I have run cinder backup-list and it giving me this.
geguileothen the parent backup isn't available, it's in error10:08
geguileoyou have to look in the logs to see what the error is10:09
geguileoor you can request another backup while looking at the c-back logs10:09

ripsomedayHi there, is this a right channel to ask cinder driver development questions, or should I ask in openstack-dev instead?10:47
*** aarefiev has joined #openstack-cinder10:47
dulekripsomeday: That's the right channel, although I'm not sure if there are a lot of driver developers here in European time.10:49
ripsomedayok, thanks, will come back later then10:50
*** aarefiev_afk has quit IRC10:50
dulekripsomeday: Well, there's no harm in asking now, maybe it'll ring a bell for someone. :)10:51
ripsomedaydulek: ok, will try :)10:52
ripsomedayso the question is - assuming that cinder driver has multiple pools. is there any proper way to delete pool? I see something like this: 1) make sure no new volumes get into pool 2) migrate all the volumes to other pools 3) do whatever needs to be done in underlying storage to delete pool. what is the proper way to do 1st step?10:54
*** Jack_Iv has joined #openstack-cinder10:54
ripsomedayor driver is supposed to just not return disabled pool in get_volume_stats, but keep accepting operation on volumes that still on that pool?10:55

jordanPsmcginnis, 2min about ?13:20
jordanPwould a feature flag, set to False by default would help here ?13:20
*** mvk has quit IRC13:21
jordanPmanage/unmanage snap is definitely a feature, though optional, of Cinder, so tests are good right ?13:21
smcginnisjordanP: Hey! Yeah, a feature flag would probably be a good answer to that.13:23
smcginnisjordanP: I love having a test to cover it. I just don't like a bunch of CIs failing because they don't support it. ;)13:23
jordanPok, I'll submit something like this right now13:23

dulekjgriffith: Not sure if you've seen that, but it catches why microversions were introduced back in Kilo:
dulekjgriffith: Not that I disagree that microversioned model has major disadvantages for developers.16:30
smcginnisI'm fine with microversions. It's more that I'm against this concept that we need to make sure anyone can always deploy from master and upgrade and everything will be supported just fine.16:31

jgriffithdulek yeah thanks!  I actually tend to point questions to that exact page16:32
jgriffithdulek I probably shouldn't have mentioned it at all16:32
jgriffithdulek but there's a number of things we've done that makes things more complex than they probably should or need to be which is dissappointing16:33
jgriffithdulek I do think there are better ways of doing it all the way around16:33
jgriffithbut it's hard to have any conversations around those things because 1. One project made a choice 2. Consistency across projects is good 3. Many (not all) people don't actually spend time trying to use this stuff16:34

dulekjgriffith: I guess cross project session at PTG called "Retrospective on Microversions" would help. :)16:35
jgriffithdulek :)16:35
jgriffithdulek the problem is honestly changing it at this point would probably be disastorous16:36
jgriffithdulek OpenStack has never been good at API's, and something like pivoting or making a significant change of any sort again would be super bad to do16:36
dulekjgriffith: Well, maybe there are ways of solving the burden that microversions place on developers? I don't think only Cinder people complain.16:37
jgriffithsmcginnis yeah, I'm kinda with you on that whole thing16:37
jgriffithdulek that's a great point16:37
jgriffithdulek and yes, I suspect there is a way to make that easier16:37
jgriffithdulek I think that's sort of where smcginnis is headed with his thoughts on things16:38
duleksmcginnis: I guess we'll need to ask ops in Milan - how many of them actually deploy from master? Maybe assumption that people do it isn't really true anymore?16:39
ildikovdulek: I have doubts about too many of them would deploy from master, but it's definitely a good data to have16:45

*** dustins has joined #openstack-cinder19:30
jgriffithhemna I know you don't really care.. but to try and explain what I was saying earlier19:32
jgriffithhemna about api versions.. what I was getting at was at the beginning of the cycle you bump to a single number; so rolling release still works19:32
jgriffithhemna any incompat/new changes go under that "new" bumped version19:33
*** dustins_ has joined #openstack-cinder19:33
jgriffithhemna that version points to any "old" call that exists and hasn't been updated19:33
jgriffithso you just use inheritance to make it all come together, but the cool thing is you also still have the ability to specify a specific (or old) version of a call if you like19:34
hemnaoh, to v419:34
hemnanot v3.17 from v3.1619:34
smcginnisjgriffith: Only problem with that I see is the way we use keystone endpoints. :/19:34
hemnasmcginnis, +119:34
jgriffithyeah, whether it's something like "v4" or whatever is debateable19:34
hemnawhich is one of the reasons micro versions were created19:35
smcginnisAnd I've certainly gotten enough crap for even creating a v3.19:35
hemnato avoid the whole keystone debacle19:35
jgriffithyeah.. smcginnis that's where you're idea of things like using a global mv is kinda nifty19:35
*** dustins_ has quit IRC19:35
jgriffithhemna smcginnis honestly I think we should route things differently in terms of keystone19:35
smcginnisI think if we were able to do one microversion bump per release, that could simplify things a lot.19:35
jgriffithhemna smcginnis in other words it shouldn't know/care about versions19:35
hemnaI think we are too reliant on keystone as well19:35
smcginnisjgriffith: +2/+a19:35
jgriffithjust and endpoint and let said endpoint figure it out19:35
hemnawe should work w/o keystone for better standalone support19:36
*** dustins has quit IRC19:36
smcginnisShould just be one endpoint, then the client decides where to go from there.19:36
jgriffithit's sort of weird to have all that version disco and stuff in keystone IMHO19:36
smcginnisOr queries the API to find out.19:36
jgriffithsmcginnis +1000019:36
jgriffithanyway, that's a high level view of what I've been trying to get at the last couple times this has come up19:36
jgriffithbetter or worse I don't know; but probably not worth taking much time on19:37
hemnaI think cinder has become way too damn complicated19:37
jgriffithhemna yeah :(19:37
jgriffithhemna complicated is "ok" when you get some real benefit from it19:37
jgriffithbut I'm unclear how much we benefit from the complexity we have introduced19:37
jgriffithanyway... maybe I'll just start my new project before big tent goes away :)19:38

smcginnispatrickeast: Been there, done that.19:59
patrickeastfinally just updated my rc file to be like
smcginnispatrickeast: Ooh, not a bad idea.20:00
smcginnisOr our help could just print out everything and tell you what version you need for those that matter. :)20:00
patrickeastsmcginnis: haha, thats the part that made me laugh20:00
patrickeastsmcginnis: because it *does* tell you what version is required, but only after you call the help with the right version20:00
scottdaThere are patches in-flight to do automatic version discovery for the CLI...20:02
scottdaThat would seem to solve most problems around "What does the server support?"20:02
patrickeastscottda: sweet, i figured it was just a temporary pain, still makes me feel better to complain :D20:03
scottdaBTW, patrickeast Happy New Year!20:03
scottdaWe've discussed whether help should show "just what is supported" or "everything, and the version required". We can always change to the latter, if that's what people want.20:04
smcginnisMy preference is the latter.20:04
scottdasmcginnis: Yes, I've logged your vote :)20:04
smcginnisGood way to discover "oh, I should upgrade my cloud so I can use this!"20:05
smcginnisscottda: Hehe. I'm persistent. ;)20:05
scottdaYeah, but deployers tend NOT to upgrade clouds...20:05
scottdaSeems a recent server had the median at Kilo20:05
scottdaThat's why it's weird to use the latest client. If your cloud is on Kilo...20:05
smcginnisExtra incentive for them to upgrade if their users are asking why they can't get access to certain versions.20:06
scottdaYou'd see all manner of features that aren't supported on the server in the Help Or CLI20:06
smcginnisBut yeah, I see your point.20:06
scottdaI really think the endpoint thing is the biggest SUX20:07
scottdaIF it weren't for that, we could do the "normal API thing", bump major versions for breaking changes.20:07
scottdahttp://<endpoint>/v4/blah...then http://<endpoint>/v5/blah20:07
scottdausers just hit the version they want. That's how most APIs work20:08
patrickeastscottda: thanks! yea i tend to like the "show everything" approach and just give an error when they try to use it20:08
smcginnisscottda: Totally agree on the endpoint thing.20:08
patrickeastthe endpoint stuff is a pain for sure20:08
scottdaBecause of keystone20:09
ildikovscottda: BTW you said you fixed the v3 endpoint locally on the meeting20:10

jonesnxyang1: six.moves.http_client will still call httplib on 2.7, correct? I believe the qnap driver is using that, among a few others.21:35

sdeathQuestion about cinder and nova.  Openstack Newton on RHEL7, basic install, as-recommended by startup guide (one controller, two comp nodes, one storage[LVM/iSCSI]) - Hypervisor report on dashboard appears to be using local disk for free space calculations instead of the volume group on the storage node.  Google doesn't seem to be able to provide any very good definitive (hence IRC).  Any guidance?22:30
*** markvoelker has joined #openstack-cinder22:32
sdeathInstance starts are failing for reasons of "not enough disk space" - original config as detailed in Openstack Newton install guide.  Tried adding "images_type = lvm" and "images_volume_group = cinder-volumes" to Nova on compute nodes.22:33
sdeathNo soap there.22:33
patrickeastsdeath: are you booting the instances from cinder volumes? if not its going to be using local storage on the nova nodes22:34
*** markvoelker has quit IRC22:34
sdeathP:  I am indeed.22:34
patrickeastsdeath: is the volume big enough for the image?22:34
sdeathIf I increase the local disk space to 100GB, none of it is used.22:34
*** markvoelker has joined #openstack-cinder22:34
sdeath... and volumes are created on the storage node.22:34
sdeath(I can see the LVs being created)22:35
smcginnissdeath: There is (or was) an outstanding Nova bug that Cinder storage consumption was being used to calculate local nova-compute host free space.22:35
smcginnisBut the hypervisor report on the dashboard will always show local disk space. That's the hypervisor info.22:35
sdeathI'm assuming it's a configuration issue on my end, at least initially.22:35
sdeathI have "image_upload_use_cinder_backend = True", "cinder_endpoint_template = http://controller/8776/v2/%(tenant_id)s", and "cinder_os_region_name = RegionOne" set.22:37
sdeath... in controller:/etc/glance/glance-api.conf.22:37

sdeathMy Googling has terminated, so far, in a conclusion that somehow disk_filter is using local_gb as a way to determine whether or not compute nodes meet the criteria to run instances.  Not enough space = that node goes byebye.22:41
sdeathNo nodes = no instances.22:41
sdeathIt doesn't seem to be understanding that the instance is backed by a volume on the storage node, and therefore it need not worry about it.  (It also doesn't appear to be checking current conditions - every time I start an instance, 30GB, let's say, it claws that 30GB out of the compute node's local storage...  without using any of it.  "df" shows no space used on the compute node.  That makes the existence of the storage node22:43
sdeathAgain, I'm assuming there's a piece of this I'm missing, to tell it "Worry about the status of THE STORAGE NODE OVER HERE -------> [Cinderblock], and forget all about the damn local storage, because we don't care about that anyway".22:44
sdeathIt is also possible that I have lost my mind and/or my reading comprehension, and am missing something directly in front of my face.22:47
sdeath(likely, even)22:47
openstackgerritRakesh Jain proposed openstack/cinder: Autoselection of IBM SVC/Storwize IO group Currently in IBM storwize_SVC driver, user can specify only one IO group per backend definition. With this change, now user can specify a list of IO groups, and at the time of creating the volume, the driver will

smcginnissdeath: No, that sounds exactly like the nova bug I mentioned.22:50
sdeathSMC:  so not a config issue, then.22:50
sdeathOr "quite possibly" not.22:50
*** catintheroof has joined #openstack-cinder22:51
sdeathThe way you said it, it sounded almost the other way around:  it's *not* using the Cinder storage to determine how much space it's got available, so it looks at the local storage, concludes it doesn't have enough, and blows chunks when requested to launch an instance.22:52

smcginnissdeath: Sorry, no, it ends up behaving the way you described.22:57
