| smcginnis | tobias-urdin: It's risky doing that. If one of the nodes are restarted while some task is running on the other node, as it comes back up it will see that task out there, think it's its own, and try to clean it up. | 13:17 |

| KeithMnemonic | I think this one is next. if someone can please review and W +1 https://review.openstack.org/#/c/589651/ queens and pike are updated and merged so now working on the ocata branch | 13:20 |
| tobias-urdin | smcginnis: I see, thanks. Is there any recommended way to improve performance for creation of multiple volumes at the same time? The only way I see otherwise would be having a lot of cinder-volume services but they operate on the same Ceph pool? | 13:21 |
| tobias-urdin | (but not the same CONF.host so they operate independently) | 13:21 |
| smcginnis | tobias-urdin: I think there are some ways to do some tuning for that, but I haven't done that myself. | 13:23 |
| smcginnis | tobias-urdin: We've merged the ability to run active/active services in a "cluster" so they are aware of each other and don't have this issues, but for the volume service we have not actually enabled any backend drivers to support it yet. | 13:23 |
| smcginnis | You mention ceph. Maybe some of the Red Hat folks have some tips on performance optimizations there. | 13:24 |
| smcginnis | There are usually a few in this channel, so we can see if they come around. | 13:24 |
| smcginnis | tobias-urdin: In case it helps, here some docs that were just added that at least gives some background on that - https://review.openstack.org/#/c/571242/6/doc/source/contributor/high_availability.rst | 13:26 |

| geguileo | tobias-urdin: what version of OpenStack are you working with? What is the performance hit you are seeing? | 15:05 |
| tobias-urdin | geguileo: Queens, doing Rally tests against Cinder I've been told by a colleague that we're getting failures/timeouts when creating large amount of volumes at concurrently, they take too long. | 15:08 |
| geguileo | tobias-urdin: empty volumes or volumes from images | 15:09 |
| geguileo | ? | 15:09 |
| *** dpawlik has quit IRC | 15:09 | |
| tobias-urdin | I'll email him and see if cans end over the Rally and Cinder logs that he hopefully collected. I would assume from images but not sure, that shouldn't involve Glance though right? With RBD backend it would just clone the volume in Ceph, but perhaps I'm wrong they are on different pools. | 15:10 |
| *** e0ne has quit IRC | 15:10 | |
| geguileo | depends on how things are setup | 15:10 |
| geguileo | also, are you setting 'rbd_exclusive_cinder_pool' to True? | 15:11 |
| geguileo | how many volumes are being simultaneously being created? | 15:11 |
| geguileo | depending on the number performance could benefit from increasing the native thread pool | 15:11 |
| geguileo | size | 15:11 |

| geguileo | rajinir: there was a proposal to do that on the last PTG, I don't remember where we ended up with it | 16:01 |
| geguileo | itlinux: I don't think it's Cinder the one that has to respect the AZ, I believe it's Nova | 16:02 |
| rajinir | ok, thanks geguileo> | 16:02 |
| geguileo | rajinir: it should be in the etherpads | 16:02 |
| rajinir | geguileo: ok will check | 16:02 |
| geguileo | itlinux: that's why in Nova you can configure it to support cross AZ attachments | 16:02 |
| geguileo | itlinux: the cinder create fails because we didn't have a way to define the default AZ in the volume type | 16:03 |
| geguileo | itlinux: I think we added the support recently | 16:03 |
| geguileo | itlinux: https://review.openstack.org/#/c/552243/ | 16:04 |

| geguileo | rajinir: line 620 | 16:10 |
| *** mriedem has quit IRC | 16:27 | |
| rajinir | <geguileo>: any chance of revisiting this for all backends? | 16:30 |
| imacdonn | what would "gp to recycle bin" mean, in a generic sense? | 16:37 |
| imacdonn | I assume it'd have to be accompanied by some sort of "undelete" function | 16:39 |
| imacdonn | to be useful | 16:39 |
| *** cmart has joined #openstack-cinder | 16:41 | |
| imacdonn | then you have to think about implication on things like quota ... does a volume "in the recycle bin" still consume quota ? | 16:44 |
| imacdonn | The Ceph thing seems to be more of an "under the covers" option ... the value-add of that is not really clear, but it doesn't appear that the "recycle bin" aspect would be exposed to users | 16:46 |

| itlinux | so now adding the allow_availability_zone_failback = true on all of them since I saw that if I create a non declear volume it fails, then try again fails then try again goes.. | 17:07 |
| itlinux | and works.. | 17:07 |
| itlinux | so that maybe the case .. | 17:07 |
| itlinux | well the other thing could be to create a flavor with it .. not sure that would work either though! | 17:09 |
| itlinux | I see it fails when it tries to use the nova az in cinder.. even though I do not see it in the list.. | 17:10 |
| *** e0ne has joined #openstack-cinder | 17:11 | |
| *** N3l1x has joined #openstack-cinder | 17:13 | |
| rajinir | imacdonn> yes, an undelete, many things to consider | 17:17 |
| imacdonn | yeah, so that would be a fairly major architectural change to cinder, I think ... possibly doable, but not trivial | 17:17 |
| *** hoonetorg has joined #openstack-cinder | 17:19 | |
| *** erlon has joined #openstack-cinder | 17:24 | |
| geguileo | rajinir: I'm not too sure myself about the whole "recycle bin" idea and there would need to be some developer who's interested in doing it | 17:25 |
| geguileo | itlinux: you say that you have to try 3 times and it goes? | 17:26 |
| geguileo | itlinux: how many API nodes do you have running? | 17:26 |
| itlinux | I have HA mode.. | 17:27 |
| *** zhaochao has quit IRC | 17:27 | |
| geguileo | itlinux: so 3 nodes, and you had to repeat the request 3 times? | 17:27 |
| geguileo | itlinux: I would say you don't have all your API nodes running the same configuration | 17:27 |
| itlinux | but that should not matter since I only have a main one and it depends on the config I notice that at time it does not work and at times it's just fine.. if I take the AZ off with one pure system it works every time.. | 17:27 |
| geguileo | itlinux: if it's HA you don't have just a main API node, you should have 3 nodes running behind HAproxy | 17:28 |
| itlinux | this is standard OOO deployment so I don't see what it should fail | 17:28 |

| imacdonn | cinder-manage is part of the 'openstack-cinder' RPM in RDO .... it's used to db sync, so it should be installed already | 18:24 |
| *** erlon has quit IRC | 18:24 | |
| itlinux | got it.. | 18:26 |
| itlinux | what command will be looking like cinder-manage service remove ?? | 18:27 |
| imacdonn | you can do 'cinder-manage service list", then find the one that you want to do delete, and 'cinder-manage service remove <binary> <host>' (where <binary> should be 'cinder-volume') | 18:28 |
| *** luizbag has quit IRC | 18:28 | |
| itlinux | ok that's not going to help me since I do not have that package on the overcloud.. | 18:28 |
| imacdonn | you'll probably have to do it on the host that's running the cinder control services (API, scheduler) | 18:29 |
| itlinux | well I can remove it directly from the db.. but that's not a good option.. | 18:30 |
| itlinux | I can disable them... | 18:30 |
