haypogeguileo: you may see that the second patch on netapp is not trivial, so i chose to have two different changes09:58
haypo(usually, i also prefer to only modify one driver per change, because of cinder complex CIs :-))09:58

haypogeguileo: "a patch that fixed more tests" did you expect that i enable all volume drivers with the first change?09:59
haypoit is what i did in a previous version of the patch, but it was a mistatke :-p10:00

Anticimexwe're using multi-backend (different Ceph pools), and i'm just playing with creating an image.10:51
Anticimexi found that if i do specify Type, the correct backend is picked.  but if i do not specify Type, the result seems to be that the image is created in a random backend10:52
Anticimexis there anyway to set a default backend when using multi-backend cinder?10:52

*** manous has joined #openstack-cinder14:28
diablo_rojodulek: Okay that's what I thought. Do we also want to enforce that people explain why there is a DocImpact tag in the commit message?14:28
dulekgeguileo: I wonder if I haven't missed the same thing in case of my SIGHUP support patches.14:28
geguileodulek: We are not passing graceful parameter to super stop method14:28
*** EinstCrazy has quit IRC14:28
dulekdiablo_rojo: I'm not sure, I think this requirement was criticized in one of the openstack-dev post.14:29
dulekgeguileo: Thanks, I'm looking through.14:29
diablo_rojodulek: Recently? Or do you by chance have the title of the email so I can go look up the ML thread?14:30
geguileodulek: But the draining works fine, which is the most important part :-)14:30
dulekdiablo_rojo: Certainly there was DocImpact in the subject. :D I think it was about the infra job that was supposed to check commit messages for that. If I recall correctly Sean Dague was the person criticizing it.14:31
dulekgeguileo: I'm terrified when something that was not supposed to work actually works.14:31

geguileodulek: That's what I imagined would be happening  XD14:35

dulekgeguileo: Buuut… Nova also have this piece of code, and they don't do it either.14:45
geguileodulek: Oh, well, that code is never called, so that's what I would expect14:45
geguileodulek: That's what I mean, we either have to remove it or make it work14:45
geguileoDuncanT: About the node draining14:46
diablo_rojoDuncanT: I promise to not +1 even though this is quite possibly the best patch I have ever seen.14:46
dulekgeguileo: This would be an operational change. I would say we shouldn't modify current behavior.14:46
geguileoDuncanT: Since we can drain the nodes manually, do we still need the operation in the API?14:47

geguileodulek: That's the one we discussed yesterday, right?14:50
dulekgeguileo: Right - I'm removing what's unused in current model.14:50
geguileodulek: You need to remove those fields from the DB, so you need a migration14:51
DuncanTUnless you're talking abotu the scheduler where node==host even if you're running several14:51
dulekgeguileo: These were added in Liberty. If I would remove it from the model I would make Liberty services unable to run on Mitaka's DB which would break ability to live upgrade.14:52

dimssmcginnis : probably is...check if pycryptodome got installed by accident there20:52

dimssmcginnis : i don't see a reference in our repo - http://codesearch.openstack.org/?q=pkcs1_15&i=nope&files=&repos=20:53
smcginnisdims: I think the exception text is coming from one of the libraries. But it's not everyone using paramiko, so a little strange.20:54

smcginnisdims: Don't want to pull you in to this.20:55

hemna_:)22:13
hemna_patrickeast, so it's either 1 of 2 things22:13
hemna_it's not in all_ips_iqns22:13
hemna_or it's not in 'entries'22:13
*** mylu has quit IRC22:14
patrickeasthemna_: yep, looks like all 4 are in the 'all_ips_iqns'22:15
patrickeasthemna_: not sure why there are two in entries22:15
hemna_only 2 items in entries22:15
hemna_and 10.0.1.10 is one of them22:15
*** IlyaG has joined #openstack-cinder22:15
hemna_which isn't getting logged out22:16
hemna_for some reason that one is in 'entries'22:16
*** IlyaG has quit IRC22:16
patrickeastwait a minute, am i reading this right and both of the 'entries' are the same one?22:16
hemna_heh22:17
hemna_I was JUST looking at that22:17
hemna_so many characters22:17
hemna_it's hard to visually compare22:17
hemna_oh22:17
hemna_entries is populated from a list of existing paths in /dev/disk/by-path22:18
hemna_that are 'iscsi' paths22:18
hemna_so there could be multiples of the same I suppose22:18
patrickeastohh22:18
patrickeastweird22:18
patrickeastthere are two still in there22:18
patrickeastlun 8 and 9 (neither of which is the volume being used)22:19
patrickeastmaybe from an older devstack test or something22:19
hemna_yup22:19
hemna_there you go22:19
hemna_that's why it's not getting logged out22:19
hemna_because there are 'volumes' from it there.22:19
hemna_stale, or whatnot22:19
patrickeastyea their broken22:20
patrickeastbut the links are still there in the system22:20
hemna_maybe a previous stack run ?22:20

patrickeastwe might want to do something like log a warning if when disconnecting from a multipath device we leave some parts behind... seems like it would be rare that some admin would actually be mixing multipath with non-multipath on the same array22:26

jgriffithmc_nair: ping22:40
mc_nairjgriffith: yo yo22:41
jgriffithmc_nair: hey ya22:41
jgriffithOn that replication review... thanks for the input22:41
jgriffithmc_nair: wanted to chat about at least one of the comments22:41
jgriffithmc_nair: https://review.openstack.org/#/c/275797/12/cinder/exception.py22:41
jgriffithmc_nair: so I'm not completely sure I follow what you're asking... are you saying since the exception is "ReplicationTarget" and the mesg is backend_id?22:42
jgriffithmc_nair: that was intentional... and the idea being not so much that theyr'e interchangeable22:42
jgriffithmc_nair: but that there's a a "replication taget" which is a thing.. and the backend_id is driver info on how to know what/where that thing is and how to access it22:43
jgriffithmc_nair: not sure if that makes sense, or if that is confusing to people?22:43
mc_nairjgriffith: sure - question is pretty basic, can see why it was tough to follow though.  Let me try to rephrase is22:43
smcginnisInvalidReplicationTarget({'backend_id': be_id, 'reason': reason}) ?22:44
*** lpetrut has quit IRC22:45
smcginnis^^ I don't think that's the intent.22:45
jgriffithsmcginnis: oh.. hurumph22:47
mc_nairsmcginnis: ok, yea I think you got to the crux of the question.  I was trying to understand the intent of that, and since we weren't creating a InvalidReplicationTarget I was having trouble following what we were going for22:47
*** j_king has quit IRC22:47
jgriffithsmcginnis: what was I smokin22:47
*** dims has quit IRC22:47
jgriffithmc_nair: smcginnis yeah... I think I was half thinking of providing a var for the backend-id that was being used as well as the reason/mesg :)22:48
jgriffithmc_nair: smcginnis I'll just dump that "(backend_id)" string out of there22:48
jgriffithleave it to log message to provide the details there22:48
jgriffithmc_nair: smcginnis make sense?22:48
smcginnisjgriffith: Works for me. Could be less confusing.22:49
jgriffithsmcginnis: mc_nair cool.. ez enough22:49
jgriffithnow...22:49
jgriffithaorourke: you're next :)22:49
mc_nairjgriffith: sounds good to me22:49
aorourkejgriffith, :)22:49
jgriffithaorourke: I don't know that there's much value in list_targets any more... do you think there is?22:50
*** Nakato has quit IRC22:50
jgriffithaorourke: or at least a reason for it in the first pass?22:50
*** Nakato has joined #openstack-cinder22:50
jgriffithaorourke: or do you want an error checker to determine what the driver configured?22:50
aorourkejgriffith, still on the fence. I think it would be nice to have a command to list possible targets when you have multiple22:50
*** kfarr has quit IRC22:50
jgriffithaorourke: ok... I still say "check the config file" but you do have a valid point22:50
*** kvidvans has quit IRC22:50
aorourkejgriffith, that way you do not have to remember/check cinder.conf to see your targets22:50
jgriffithaorourke: and it's not that hard to do... I'm just being super lazy :)22:51
aorourkejgriffith, i can see it being a nice command to have, but not the end of the world22:51
jgriffithaorourke: also, the migration tests... yes, it's 64.  Note that 63 is remove iscsi targets table... the rep stuff is in fact 6422:51
jgriffithaorourke: yeah... fair enough.  I'll put it back together22:52
aorourkejgriffith, makes sense22:52
*** changbl has quit IRC22:52
aorourkejgriffith, what will the API calls for these commands look like?22:52
aorourkejgriffith, it is no longer on an individual volume22:52
jgriffithaorourke: no cheating... you'll just have to wait22:52
jgriffithaorourke: so I'm moving that stuff to services... so it's by host22:53
jgriffithaorourke: you say "cinder list-replicaton-targets <c-vol-host>"22:53
aorourkejgriffith, thought that would be the direction. Definitely belongs there now it is by host22:53
jgriffithvol stuff all goes away IMO22:53
aorourkejgriffith, are you also working on the python-cinderclient patch?22:53
jgriffithaorourke: just enough to run my tests22:54
jgriffith:)22:54
jgriffithaorourke: it's going to be hard enough to finish this and get unit tests while all the rest of you are writing your drivers :)22:54
jgriffithaorourke: and I keep hitting silly merge conflicts because I'm slow :(22:54
aorourkejgriffith, i was going to see if you needed any help on the cinderclient side but not sure of the API calls quite yet22:55
jgriffithaorourke: yeah, let's synch up tomorrow morning maybe22:55
smcginnisaorourke, jgriffith: Would be good to get the client side set.22:55
smcginnisDeadline for that is sooner.22:56
jgriffithI think I'll have enough of it that we can do that.  And I can share what I have in the client if it's not something I can just push up as is22:56
aorourkejgriffith, sounds good22:56
jgriffithsmcginnis: what is the client deadline by the way?22:56
*** gouthamr has quit IRC22:56
jgriffithaorourke: if you have bandwidth and want to help with things we can definitely work together on a few things22:56
aorourkejgriffith, and to clarify, a c-vol-host, not a backend name? So it is a foo@bar#pool type thing?22:57
jgriffithaorourke: yes22:57
aorourkejgriffith, I have some time to work on it as well22:57
jgriffithaorourke: I want to be able to use "cinder service-list" to get info22:58
jgriffithaorourke: rather than have the mess that was created with manage allowing people to just do *whatever* they want22:58
aorourkejgriffith, that would probably be best. don't even allow the driver to list targets22:58
aorourkejust all replicated hosts22:58
aorourkefrom cinder service-list22:58
jgriffithaorourke: that's why I removed the list_targets thing22:58
jgriffithaorourke: and yes, I've already added "recpliation_status" and "active_backend_id" to 'cinder service-list'22:59
aorourkejgriffith, i see now. so it would not need to be in the driver/manager, just an api call for it22:59
jgriffithaorourke: so what I have written right now.. yes, you're correct.  BUT if we bring back list-targets then that needs to go through down to the driver... but that's still host based23:00
jgriffithaorourke: not sure if we're going in a circle here :)23:00
jgriffithaorourke: I'll code it up, I think you'll be happy with it when you see it23:00
