*** alonma has quit IRC15:01

jungleboyjskp: Do you have a particular reason for being interested in Cinder?15:01
*** ts897 has quit IRC15:02
*** ts897 has joined #openstack-cinder15:03
skpIf Cinder was a real life application I would be using it because of the great comfort it offers.15:03
skpI have read the description which said "  it virtualizes the management of block storage devices and provides end users with a self service API to request and consume those resources without requiring any knowledge of where their storage is actually deployed or on what type of device."15:04
*** chlong has quit IRC15:05
smcginnisChason: Sorry, I have a firedrill here so I'm a little distracted right now.15:06
smcginnisChason: But basically, pools are reported by your storage backend.15:06
smcginnisChason: What type of storage are you using?15:06
skpI am a CS student and I have done courses like database systems, Principles of Information security, computer networks etc.... Virtual data storage is an ongoing research field and I can relate this description to the Pied Piper idea (a TV series reference: Silicon Valley). hence I want  to learn more about the project and see if I can contribute to this!15:07

jungleboyjskp: Well, to be involved you need python skills and having a storage background helps.  Otherwise start by taking a look at our Wiki:  https://wiki.openstack.org/wiki/Cinder15:11
smcginnisChason: There are others here that know the LVM stuff much better than I do. But is there a reason you want/need multiple pools?15:12
skpI have done several projects in Python and I consider myself well versed with it15:12
skpCan you help me on how to get started ?15:13
jungleboyjskp:  That wiki has a lot of information about the project to start with.  We also have  our developer wiki:  https://docs.openstack.org/developer/cinder/15:13
ChasonYes, I am fixing a doc bug, see https://bugs.launchpad.net/openstack-manuals/+bug/166387315:13

jungleboyjskp: Can't say that working on Cinder is like Pied Piper, but I do love that show.15:14
jungleboyjskp: Yes ...15:14
*** lucasxu has joined #openstack-cinder15:15
jungleboyjskp: If you don't have a Linux box you can download Virtual Box for free and ubuntu 14.04 to build a VM to run devstack in.15:15
skpI use mac. Other than installing a VMware there is no other way ?15:15
ChasonI need setup an env to correct these commands' output.15:15
skpI was typing the same thing15:15
smcginnisChason: Ah, OK. So you just need multiple backends in order to do a migration then.15:15
smcginnisChason: You should be able to configure multiple LVM backends.15:15
smcginnisChason: This might help: https://docs.openstack.org/admin-guide/blockstorage-multi-backend.html15:16
jungleboyjskp: That is the best way to go.15:16
skpMy VMware fusion shows up all the possible problems existent in this world :/ (or even more)15:16
jungleboyjskp: Otherwise, the way I got started is just reading the code and sitting in on the weekly Cinder meetings.  Can learn a lot that way.15:16
Chasonsmcginnis: Oh, it does!15:16
skpHow I access weekly Cinder meetings >15:17
skp?15:17
Chasonsmcginnis: Thanks, smcginnis!15:17
jungleboyjskp: :-(  Bummer.  Well, sounds like the first step is to work through those issues.  :-)15:17
smcginnisChason: No problem. Let us know if you run into any issues getting it set up. Usually someone around that can at least point you at relevant documentation. ;)15:17
skp@jungleboyj I need to submit patches to get my application accepted for the outreachy right?15:18
*** lucasxu has quit IRC15:18
smcginnisskp: Here's our weekly meeting info: https://wiki.openstack.org/wiki/CinderMeetings15:18
skpsmcginnis: Thank you so much!15:19
jungleboyjskp: I am not sure what is required for some of those programs.  diablo_rojo can help answer those questions.  She is a developer advocate.15:20
jungleboyjskp: Could chat with her when she logs on.15:20
skpSure, that will help.15:20
skpjungleboyj: I will try to fix the issues with my VMware till then.15:21
skpHave a great day!15:21
smcginnisskp: If you can get a Linux instance to work with and get devstack running that will be a great first step.15:21
skpsmcginnis: On it!15:23
waj334So, accept_transfer in the manager returns a dict and I noticed it's just modifying a volume entry in the database. Would it be better to just return the updated volume object instead of this dict? Also, I can't seem to find any docs on this so I can really understand the behavior of this function15:29

dikonoorxyang1: hi17:19
xyang1dikonoor: hi17:19
dikonoorxyang1 : Are you xing-yang?17:19
xyang1dikonoor: yes17:19
dikonoor xyang1 : ok great :) ..This is about consistency groups quota..I see that you have worked on different changes arount consistency groups (including adding support for cggroups quota in cinderclient)17:20
*** jwcroppe_ has joined #openstack-cinder17:20
xyang1dikonoor: sure17:20
dikonoorbut I tried the cgquota and it doesn't look like it's implemented17:21
dikonoorxyang1: I am not sure if the community is in the middle of something and if support for this quota has been withdrawn or not..17:21
xyang1dikonoor: right now it is a setting that cannot be changed, but there is a spec on adding that support17:21
*** e0ne has quit IRC17:22
*** xyang has joined #openstack-cinder17:22
dikonoorxyang1 : The only cg group quota related canges I see are her >>https://github.com/openstack/cinder/blob/master/cinder/quota.py#L45 , which is setting the default value to 1017:22
xyangdikonoor: https://review.openstack.org/#/c/306946/17:22
*** jwcroppe has quit IRC17:23
xyangdikonoor: right, the original change is very simple and not adjustable.  the above spec adds quota management for it17:23
dikonoorxyang: ok..and this will be applicable only for cinder v3 I guess?17:25
xyangdikonoor: right17:25
dikonoorxyang: I read the spec on moving cggroups into volume groups and how there are going to be overlaps between the two in ocata , which will subsequently go away and get completely replaced by volume groups in Pike ..I currently use cinder v2 and I am able to use volume groups17:26
xyangdikonoor: also this will apply to generic volume groups, not to consistencygroups directly17:26
dikonoorxyang: Will the concept of cg groups get completely replaced by generic volume groups ? (in Pike)?17:27
xyangdikonoor: we need to discuss about the details at PTG17:27
*** Apoorva_ has joined #openstack-cinder17:28
xyangdikonoor: drivers need to move the CG support to groups in Pike and we'll also force people to migrate from CG to groups17:28
dikonoorxyang: ok . So currently the generic vol groups are available in v2 but the volume groups quota will be available only in v317:28
xyangdikonoor: we have to disabled the CG APIs yet.  so that is something we need to discuss17:28
*** Apoorva has quit IRC17:29
xyangdikonoor: generic volume groups were added in v3.  I don't know how you use v2 with it17:30
xyangdikonoor: unless if you are using CG commands?17:30
dikonoorxyang : yes ..when we invoke cg rest api, it invokes the group_api.create17:30
xyangdikonoor: I have to specify a os-volume-api-version to be 3.xx to use groups commands17:30
xyangdikonoor: that's part of the migration, hidden from the user17:31
xyangdikonoor: you can't directly use groups commands in v217:31
*** shubham0d has joined #openstack-cinder17:32
dikonoorxyang : ok..I did not check that..I checked cg commands and rest api and then noticed this..Another thing I obeserved is around the rbac rules17:32
dikonoorxyang : Now there are checks for two sets of policy.json rules17:32
dikonoorxyang : one is the old set of cg rules ; the other is the new group rules17:32
xyangdikonoor: when you use CG commands, it should check policies for CG17:33
xyangdikonoor: when you use groups commands, it should check policies for groups17:33

dikonoorhttps://github.com/openstack/cinder/blob/master/cinder/api/contrib/consistencygroups.py#L18817:36
dikonoorThis is the cggroup create flow17:36
xyangdikonoor: what about it?17:37
dikonoorthe line there validates this rules >> "consistencygroup:create":17:37
dikonoorxyang : https://github.com/openstack/cinder/blob/master/cinder/api/contrib/consistencygroups.py#L189 ..this line internally validates "group:create":17:37
dikonoorxyang: SO the cggroups rest api now has two set of rbac rules being validated17:38
dikonoordikonoor: I assume once the migration happens, it will get cleaned up17:38

dikonoorxyang : one more related question19:12
xyangdikonoor: hi19:12
dikonoorxyang: I was trying to create some cggroups and ran into GroupLimitExceeded: Maximum number of groups allowed (10) exceeded (HTTP 413)19:13
dikonoorand I thought it was caused because of the quota_groups19:13
xyangdikonoor: yes19:13
dikonoorcfg.IntOpt('quota_groups',19:13
dikonoor               default=10,19:13
dikonoor               help='Number of groups allowed per project'),19:13
xyangdikonoor: you'll have to delete some groups19:13
dikonoorxyang: but I would like to update the count to say something like 100. So, I tried this by adding an entry in my cinder.conf >> quota_groups = 10019:14
dikonoorbut that doesn't seem to work19:14
xyangdikonoor: no, you can't change it now19:14
xyangdikonoor: that's what that spec will be doing19:15
dikonoorxyang : oh..so there's no way an openstack deployment can have more than 10 cg groups now?19:15
xyangdikonoor: no19:16
dikonoorxyang: but that will be a huge limitation for environments that have more than 10 cggroups.. I guess earlier it used to be quota_consistencygroups and using that it could be updated?19:17
xyangdikonoor: we have to wait for that quota mgmt spec to be implemented19:17
xyangdikonoor: to be honest, I don't think we should even have quota for groups19:18
xyangdikonoor: we already have quota for volumes19:18
xyangdikonoor: anyway, that's already designed that way19:18
xyangdikonoor: are you testing a specific driver?19:18

dikonoorxyang:ok19:21
xyangdikonoor: are you using devstack?19:23
dikonoorxyang: im at ocata..19:23
xyangdikonoor: that quota table is set up at db migration time19:24
xyangdikonoor: so if you change quota_consistencygroups  after that, it will not change it in the db19:24
dikonoorxyang: it will not19:25
xyangdikonoor: that is correct19:25
dikonoorthe quota table is intended to be updated only via the quota rest api19:25
xyangdikonoor: so that is working as expected for now19:25
*** asselin has quit IRC19:25
dikonoormy question was - the default value for quota_consistencygroups is 10 from /cinder/quota19:25
xyangdikonoor: yes, that default of 10 is used at migration time19:26
xyangdikonoor: so what have you done after you changed it in cinder.conf?19:26
dikonoorif i wanted that to be 100 ..if I had added an entry in cinder conf [default] quota_consistencygroups=100 , would that have worked ? It works for other cinder quotas19:26
dikonooradd in cinder.conf and restart service19:26
xyangdikonoor: restart service alone won't work19:27

castuloHi, good afternoon. I have a question you guys may be able to help me answer, I have a devstack that includes Cinder installed inside an LXC container, it was installed correctly, but when trying to create a volume I am seeing this error in the log (and my volume end up in error state): /dev/stack-volumes-lvmdriver-1/volume-24e810ef-3f60-472d-b775-5125faa5ed9e: not found: device not cleared  Aborting. Failed to wipe start of new LV.19:59
*** xyang has joined #openstack-cinder19:59
castulodo you guys have any idea why that may be happening?20:00
castuloif I try creating a logical volume manually inside the LXC container I get the same error, unless I use the "-Z n" argument when creating the logical volume, then it works20:00
smcginniscastulo: Not sure. There was a different team working on running Cinder services inside of a container. I haven't tried lately myself.20:01
smcginniscastulo: I know there were some differences with how LVM needed to be handled. Just don't know the specifics.20:01
*** xyang has quit IRC20:02

castulosmcginnis: ok, thanks. If you guys remember who that team was or any other info that could point me in the right direction I'd appreciate it. Thanks :)20:03
jgriffithcastulo there are some *tricks* to doing things like LVM and iSCSI inside containers20:04
jgriffithcastulo Docker let's you get away with it using things like privileged mode and mounts20:04
jgriffithcastulo LXC is a bit trickier.. the folks that have done most of that work with LXC are the Ansible OpenStack folks (Rackspace Private Cloud)20:05
*** xyang has joined #openstack-cinder20:05
jgriffithLXC I don't know that the iSCSI problem is solved on LXC at all currently20:05
jgriffithOn the Docker side, the Kolla project is what you would be interested in20:05
*** ksumit has quit IRC20:05
castulojgriffith: I see, my lxc container is privileged, but I'm not mounting anything related to that.... not sure what I'd need to mount.20:06
jgriffiththere's also an OLD project called dockenstack that ewindisch used to maintain, but I don't know that it exists any longer20:06
jgriffithcastulo if you're using the LVM driver it needs to put a tgt infront of the LV device20:06
castulojgriffith: asking the OpenStack ansible guys is a very good idea20:06
jgriffithcastulo they're focused on docker FWIW, which is different than how LXC works for this20:07
*** kaisers_ has joined #openstack-cinder20:07
jgriffithcastulo with docker I just mount /etc/iscsi, /dev/disk/<xxxx> and use host network namespace20:08
jgriffiththat "works" (ish)20:08

xinli@smcginnis: let me try22:03
jgriffiththen there's also some good times around quota failures on the cinder side trying to create the snapshot in the first place22:04
