namnhdulek, I am testing the work-follow of upgrade as your patch set: https://review.openstack.org/#/c/393395/11/doc/source/upgrade.rst@16908:34
namnhdulek, I am wondering that the gracefull shutdown can run when I kill the process ID of cinder-volume. If:08:35
namnhdulek, - No: In my option, the feature will be run when there is SIGTERM [3]. Basically, when I run "kill" command to kill a process then it will send SIGTERM signal [4] to stop the process. So when I stop cinder-volume by "kill" command so the feature can be run. What do you think?08:35
namnhdulek, - Yes: I think the problem here is due to cinder-scheduler. Because when I stop cinder-volume on server1, cinder-scheduler did not update real time so it still send three requests to create volume to sever1 and after a period of time, cinder-scheduler will update the status of cinder-volume and send remain request to server2. Is my explanation right?08:35
namnhdulek, I am upgrading from Mitaka to Newton.08:36
namnhdulek, I fogot to write down my scenario, please read this line first: My scenario is that I kill the process ID of cinder-volume one server1 by "kill" command during creating volume after that starting new cinder-volume with next release on server 2. As you can see, there are 3 request which does not still handle [1], on horizon you can see 3 volumes have "creating" status. [2]08:39

openstackgerritwangxiyuan proposed openstack/python-cinderclient: Support filter volumes by group_id  https://review.openstack.org/41006409:10
duleknamnh: It's because of service heartbeat timeout - the scheduler still thinks the killed c-vol is up and running.09:10
duleknamnh: How do you achieve Active/Passive setup? Does your two cinder-volume services listen on the same RabbitMQ queue?09:11
openstackgerritAdelina Tuvenie proposed openstack/cinder: Move windows drivers to versioned objects  https://review.openstack.org/40364109:11
atuveniecan someone take a look over this patch please: https://review.openstack.org/#/c/403641/09:12
duleknamnh: I think there are two ways of fixing this - either by making both of your c-vols to listen on the same queue.09:12
atuvenieit's to fix some issues with snapshotting on windows smb09:12
duleknamnh: Or - before killing the first cinder-volume service - disable it using cinder service-disable.09:12
duleknamnh: Then scheduler won't schedule any new volumes there.09:12
*** lpetrut has quit IRC09:13
duleknamnh: Please however note that if that's the only running c-vol in the deployment, then you'll get NoValidHost for volumes created when it's disabled.09:13

*** mvk has quit IRC09:23
namnhdulek, The first your question. You are right, I install two Controller nodes including Cinder. then on controller1, I modified cinder.conf to point DB-server and Rabbitmq server. I think this way to create a enviroment as fast as possible to test cinder-volume. Are there any problems with this architecture?09:27
*** alonma has joined #openstack-cinder09:28
namnhdulek, For first your solution. I think this is can created by modifing cinder-volume on two servers with the same hostname. How it seems diffcult to do this because, we should not create two severs with the same hostname. What do you think?09:28
namnhdulek, For second you solution: I tend to think to follow this solution and do you think it need to update to your patch set at line: https://review.openstack.org/#/c/393395/11/doc/source/upgrade.rst@18309:30

namnhdulek, btw, If I kill the cinder-volume process by using "kill" command. Can the gracefully shutdown feature be run before shutdown?09:33
duleknamnh: kill command will send SIGTERM, which will gracefully shutdown the service.09:35
duleknamnh: kill -9 will send SIGKILL, which will destroy the service immediately, in a non-graceful manner.09:35
duleknamnh: Running 2 cinder-volume services with the same hostname is standard strategy in case of A/P deployments.09:35
duleknamnh: Red Hat OSP does that for example.09:36
*** eantyshev has joined #openstack-cinder09:36
duleknamnh: And yes, I think I can extend the docs to cover the problems you've explained.09:37
namnhdulek, Oh. that's excited. However my concern is that if we use Pacemaker to monitor resource such as cinder-volume. we can not do this if there is the same hostname.09:39
duleknamnh: Ah, that thing. ;)09:40
duleknamnh: Just set it in cinder.conf.09:40
duleknamnh: It will overwrite what's set on the server itself.09:40
namnhdulek, ^^ I don't still image this solution. What line in cinder.conf we need to set?09:43
namnhdulek, it mean, we still use Pacemaker with the same hostname09:44
duleknamnh: It's ``host`` option in either [DEFAULT] or your backend section. It will only be used internally by Cinder - to determine queue names.09:45
duleknamnh: I assume you're using RabbitMQ?09:46

namnhdulek, Ohh, I see, I see. Rabbitmq will see only queue and Pacemaker still see two hostnames. is that right?09:50
duleknamnh: Yes, that's right.09:51
namnhdulek, I think this is good idea, This will fix a case that when we change cinder-volume, we can still control the volumes which is created by old cinder-volume :)09:52

kukaczhi, I got an issue with Cinder Kilo, Ceph backend - some volumes appear as attached to "NULL" after some time, even though they're still attached to running instance15:51
*** jwcroppe has quit IRC15:51
kukaczon nova side eg. `openstack server show` displays the volume correctly15:52
hemnahow do you see it attached to NULL ?15:52
kukaczin `cinder list` or `openstack volume list` output, in place of instance it returns NULL15:53
kukaczI've also looked into the cinder database, table volume_attachment, where I see the instance_uuid with value NULL15:54
openstackgerritAleksey Ruban proposed openstack/cinder: Nexenta: Added ZFS cleanup in NexentaStor4 iSCSI driver  https://review.openstack.org/38267015:54
*** alonma has joined #openstack-cinder15:54
kukaczI haven't observed the moment yet, when it changes to such state. after instance creation and even on major part of instances it's correct15:55
hemnahmm that really is strange15:55
kukaczin `cinder show` I can even find correct "attachment_id" returned. just the instance (server_id) id is missing15:56
kukaczso the attachment records appear to be in place, however instance ID's turn to NULL15:57
kukaczI wonder if that might been some bug in Kilo, but could not find anything15:57
hemnaI've not heard of that one yet15:57
hemnathat value is set during attach time, and isn't unset15:57
hemnait's quite strange15:58

erlonDuncanT: https://review.openstack.org/#/c/316540/16/specs/ocata/cinder-volume-rollback-snapshot.rst@2517:46
waj334scottda: I'm all for a single implementation of microversion selection17:47
DuncanTerlon: Ah yes, I remember17:48
erlonDuncanT: so, Im trying to compair this concern you raised with the implementation that we have in NFS Snapshots17:48
erlonDuncanT: where we call Nova api to do te snapshot if the volume is attached17:49
DuncanTerlon: I've not looked at that code in detail17:49
DuncanTerlon: It looks like your reply to the comment is right though: we need to add some call to nova to ensure that the instance stays shutdown until the revert has finished, which might be a long time in some instances17:50
erlonDuncanT: getting the instance status wouldn't solve the problem?17:51
DuncanTerlon: Or make nova orchestrate it, you call "nova volume rollback" and it makes sure the instance is shutdown and stays shut down for the duration17:51
DuncanTerlon: No, the instance status can change17:51
DuncanTerlon: We need to lock the instance so that is stays down until we're done17:51
DuncanTerlon: Otherwise we can be writing to the root disk of a live instance, and that means data corruption17:52
erlonDuncanT: so either ways we would need to add something to Nova17:52
DuncanTerlon: Yes, I believe so17:52
*** atuvenie has joined #openstack-cinder17:52
erlonDuncanT: after you wrote taht I started to think about the 2 call approach, and seemed reasonable17:52
DuncanTerlon: Otherwise something else (another command line, horizon, some housekeeping or recovery process) can set the instance booting again while we're still doing data transfer17:53
erlonDuncanT: though the user could call unsafe using directly the API right?17:53
DuncanTerlon: They can call direct if we expect nova to orchestrate, which is why I don't think this should be part of the normal rollback api, but rather a totally separate api entry point, and we *don't* add it to the CLI, only the library17:54
DuncanTerlon: Like e.g. reserve is17:54
erlonDuncanT: hmm17:55
*** jordanP has quit IRC17:55
DuncanTerlon: If cinder is orchestrating and calls nova to lock the state of the instance as shutdown, then there's no risk of that17:55
DuncanTerlon: In either case, the failure recovery code is... messy17:55
*** alonma has joined #openstack-cinder17:56
DuncanTerlon: I still think a far better fix is to add a call in nova to do change the root volume while the instance is shutdown.17:56
erlonDuncanT: you mean in case of a shutdown of any of the invilved services right?17:56
erlonDuncanT: change the root volume??17:57
DuncanTerlon: That would be the most obvious failure mode, yes17:57
DuncanTerlon: Sure. the main use case for this is to rollback a root volume17:57
DuncanTerlon: If you could just swap the root volume, suddenly you don't need 'live' rollback17:58
DuncanTerlon: People will want it anyway (performance, quota), but the use case is covered17:58
DuncanTerlon: It isn't really live rollback anyway, since the instance needs to be shut down17:58
*** crose has joined #openstack-cinder17:58
erlonDuncanT: yeah tha would be a prolem, but as we are considering that, once the user started the revert, he/she is knowing that his data in the current volume is damaged17:59
DuncanTerlon: It is just getting round the nova restriction that you can't detach the root volume17:59
DuncanTerlon: Yeah, but you still have to give (preferably) the tenant or (at minimum) the operator some way to retry the rollback or something...18:00

*** lpetrut has quit IRC18:01
DuncanTerlon: It can fail for any reason, including an exception from the backend. Our table of allowed operations once that happens (error* state volumes or sometimes it just goes back to available, or attached....) is already a total mess18:02

*** Julien-zte has joined #openstack-cinder18:03
erlonDuncanT: mhm, for what I could think now, in that case the operation could just be started18:03
DuncanTerlon: Started again on service restart? That should be ok, yes, I think. That decission should probably be in the details of the spec I think18:04
erlonDuncanT: the initial state of the volume would be lost, and once we have the data we want in the snapshot, which we will create a hidden volume from, we can just start over18:04
DuncanTerlon: It will need testing, retesting with H/A, etc18:04
erlonDuncanT: Ill sk tommylikehu to add it18:05
erlonDuncanT: good point18:05
DuncanTerlon: We need to be able to tell the difference between cinder doing the data copy and driver based reverts that failed18:05
erlonDuncanT: why?18:05
DuncanTerlon: Starting a datacopy for a driver revert that failed could be a total mess. Maybe driver failure just puts the volume in error_reverting?18:06
*** enriquetaso has quit IRC18:06
DuncanTerlon: Depending on the backend, the volume could be in a totally arbitrary state18:06
DuncanTerlon: Including dangerous ones18:07
DuncanTerlon: e.g. where revert takes 5 rest calls and only the first 3 are done then c-vol gets restarted... what is the right thing to do? Certainly not to start writing data to the vol18:07
erlonDuncanT: if the failure was in the backend, retry the process would just fall in the same error18:07
DuncanTerlon: Not if it was interrupted rather than just failed. If it failed clean we can put the volume in error_reverting and it becomes easier18:08
erlonDuncanT: i think both should be error_reverting, but we should not retry the revert on cleanup18:08
DuncanTerlon: But if you come up and the volume is in state reverting, what do you do?18:08
DuncanTerlon: You could require the driver be idempotent I guess18:09
DuncanTerlon: Then you just call the driver again18:09
erlonDuncanT: idempotent?18:09
DuncanTerlon: So you require the driver to be safe to call revert twice if it gets interrupted/restarted18:09
DuncanTerlon: Just needs documenting in the spec and dev ref and left to the driver writers18:10
erlonDuncanT: by safe you meant that the admin should guarantee that?18:10
DuncanTerlon: That the driver author is required to do whatever magic is required to make it safe18:11
*** atuvenie has quit IRC18:11
erlonDuncanT: hmmm18:11
DuncanTerlon: So the service can just call it again on restart, and the driver is required to cope18:11
