| bhagyashris | Hi all, can anyone please tell me the list of backend which are supporting the multi-attach functionality. I mean to say when I create the volume using the default lvm backend (driver-lvm ) by giving the multiattach flag value as true (cinder --debug create --allow-multiattach --name test666 1) then it's not creating the volume successfully and goes into the error state | 14:07 |
| *** dave-mccowan has joined #openstack-cinder | 14:09 | |
| bhagyashris | so which drivers/backend are supporting fo same | 14:10 |
| ildikov | bhagyashris: if you're deploying from latest master then it's supposed to work with LVM | 14:10 |
| *** arnewiebalck_ has joined #openstack-cinder | 14:10 | |
| ildikov | bhagyashris: also we're deprecating the usage of the flag for volume create | 14:11 |
| ildikov | bhagyashris: the new way to create a multi-attach volume is to create a multi-attach volume_type and create the volume with that | 14:13 |
| bhagyashris | ildikov: ok, thank you :) just one query i mean i am not aware about the last part creating th mulit-attach volume_type | 14:17 |
| bhagyashris | and hen create volume | 14:17 |
| ildikov | bhagyashris: https://docs.openstack.org/cinder/latest/admin/blockstorage-volume-multiattach.html | 14:18 |
| bhagyashris | ildikov: i have just pull the latest master and create volume using command cinder --debug create --allow-multiattach --name test666 1 but getting some error at c-sch side | 14:18 |
| ildikov | bhagyashris: what is the error? | 14:19 |
| bhagyashris | Feb 05 19:50:48 openstack-VirtualBox cinder-scheduler[14795]: ERROR cinder.scheduler.flows.create_volume [None req-1a8882da-4161-4664-b1c5-c6e6828605b6 admin None] Failed to run task cinder.scheduler.flows.create_volume.ScheduleCreateVolumeTask;volume:create: No valid backend was found.

| openstackgerrit | Merged openstack/cinder master: Add missing MV history for 3.50 https://review.openstack.org/540739 | 14:23 |
| bhagyashris | ildikov: i have gone through the doc you share and tried to create the volume that way but still getting same eeror as share above so IMO LVM is not supporting the multi-attach | 14:25 |
| ildikov | bhagyashris: we are testing with LVM in Tempest and it works | 14:27 |
| ildikov | bhagyashris: are you having the client installed from the latest source as well? | 14:28 |
| bhagyashris | ildikov: one thing i have observed in doc is they have mentioned "You’ll need to ensure you have a backend device that reports support of the multiattach capability, otherwise scheduling will fail on create" so How we can found out that which drivers are supporting multi-attach functionality | 14:28 |
| bhagyashris | ildikov: checking... | 14:28 |
| *** david-lyle has quit IRC | 14:30 | |

| *** dklyle has quit IRC | 14:32 | |
| ildikov | bhagyashris: we turned it off in the capabilities until we have the full implementation ready for multi-attach | 14:34 |
| ildikov | bhagyashris: and we turn it back on for drivers that support it, here's lvm: https://github.com/openstack/cinder/blob/master/cinder/volume/drivers/lvm.py#L279 | 14:34 |
| bhagyashris | ildikov: tried with latest client as well but still get same error | 14:34 |
| ildikov | bhagyashris: can you create the volume without multiattach? | 14:35 |
| bhagyashris | ildikov: yes | 14:36 |
| ildikov | bhagyashris: one more thing, I think you will also need to use the microversion for multi-attach in the request which is 3.50 | 14:36 |
| ildikov | bhagyashris: so add this to the create call --os-volume-api-version 3.50 | 14:38 |

| ildikov | mriedem: that was my first thought too... :/ | 18:06 |
| smcginnis | pandy: Where do you see a full backup setting incremental=True? | 18:06 |
| smcginnis | pandy: is_incremental is false in your paste: http://paste.openstack.org/show/662554/ | 18:07 |
| pandy | smcginnis: if its not dependent backup, then its taking full backup ? how it referring original data and restoring, Also is it possible to restore volume using "cinder backup restore <first_full_backup_vol_ID> <latest_incremental_backup_ID> " because assume in case i lost original volume, with fullbackup and last backup should able to restore like disaster recovery | 18:07 |
| smcginnis | pandy: It has dependent backups, because the second incremental one is dependent on it. | 18:09 |
| jgriffith | mriedem: ildikov is it possible that the config and api settings aren't quite all up to speed somewhere in there? | 18:09 |
| pandy | smcginnis: I am seeing incremental=True while doing "cinder backup-create <volume_ID> --incremental, if i am not passing --incremental "Incremental =False" do we need to pass --incremental in ceph as backend type ? | 18:09 |

| ildikov | jgriffith: we force the multi-attach tests to use the 2.60 Nova microversion otherwise they would fail on the Nova side | 18:10 |
| mriedem | jgriffith: the job is running on master so it should all be up to date | 18:10 |
| mriedem | this isn't a multiattach test | 18:10 |
| smcginnis | pandy: Sorry, I don't understand what you are asking. | 18:10 |
| mriedem | it's just a regular old volume attach test | 18:10 |
| ildikov | mriedem: sorry, didn't look up the exact test just saw the job and assumed... :) | 18:11 |
| mriedem | the attach starts in the compute logs here http://logs.openstack.org/57/537957/2/gate/nova-multiattach/456f61e/logs/screen-n-cpu.txt.gz#_Feb_05_15_52_28_000158 | 18:11 |
| smcginnis | pandy: As far as restore goes, I believe it's just "openstack volume backup restore 905062f3-53d9-44ed-ba50-4eabc1c04662 1ad556f3-6190-4658-9bb3-8ec72eca6ead" | 18:11 |

| mriedem | in n-api this is where we create an attachment on the volume http://logs.openstack.org/57/537957/2/gate/nova-multiattach/456f61e/logs/screen-n-api.txt.gz#_Feb_05_15_52_27_845552 | 18:13 |
| ildikov | mriedem: the new flow in Cinder internally uses initialize_connection though even if it's not the os-initialize_connection call anymore | 18:13 |
| jgriffith | ildikov: yeah; but that call in the first log is hitting the API server | 18:14 |
| ildikov | jgriffith: so answering your question, I have no idea :) | 18:14 |
| mriedem | ildikov: the error in the n-cpu logs says it's failing to initialize the connectoin, which is only from nova's cinder api initialize_connection client call | 18:14 |
| jgriffith | ildikov: unless I'm not following (which is quite possible), the log shows it being called from Nova | 18:14 |
| mriedem | POST attachments returns a 202? | 18:15 |
| jgriffith | at first I thought maybe the exception was just bubbling up; but it looks like the extension was actually called on the API server? | 18:15 |
| pandy | smcginnis: As you said "As far as restore goes, I believe it's just "openstack volume backup restore 905062f3-53d9-44ed-ba50-4eabc1c04662 1ad556f3-6190-4658-9bb3-8ec72eca6ead"" here is my question, assume original volume is deleted "1ad556f3-6190-4658-9bb3-8ec72eca6ead" can't we restore in that case, like with first backup id, it was fullbackup i think so ? | 18:15 |
| ildikov | jgriffith: mriedem's first link looks like an attachment_update call to me | 18:15 |
| mriedem | REQ: curl -g -i -X POST http://198.72.124.149/volume/v3/98b826c754214cdeae569d147336c6fc/attachments | 18:16 |
| mriedem | attachment_update would be a PUT | 18:16 |
| jgriffith | ildikov: I agree; but can't figure out this: http://logs.openstack.org/57/537957/2/gate/nova-multiattach/456f61e/logs/screen-c-api.txt.gz#_Feb_05_15_52_28_224506 | 18:16 |
| mriedem | jgriffith: that's n-cpu calling os-intialize_connection on the volume actions api | 18:16 |
| mriedem | which should only happen for an old style attachment, | 18:17 |
| mriedem | which we shouldn't be doing in this job, and i can see the n-api creating an attachment record on that volume | 18:17 |
| jgriffith | mriedem: right... am I incorrect in thinking that *that* is the problem here? | 18:17 |
| mriedem | i think it is a problem yes | 18:17 |
| mriedem | attachment_update would likely maybe also timeout eventually calling lvchange too, | 18:17 |
| mriedem | since attachment_update is also an rpc blocking call | 18:18 |
| smcginnis | pandy: You can restore to a different volume than the backup was created from. | 18:18 |
| jgriffith | yeah, the lvchange thing is another problem | 18:18 |
| jgriffith | we see those every year or so it seems :( | 18:18 |
| smcginnis | jgriffith: Or every 6 months. :/ | 18:18 |
| jgriffith | smcginnis: 6/12 close enough :) | 18:19 |
| smcginnis | Seems like it was more recent than that. | 18:19 |
| jgriffith | haha, nooo; I meant you say 6, I say 12.... close enough :) | 18:20 |
| jgriffith | smcginnis: anyway... bottom line is lv activate has been a problem since day 1 and can be quite a few different things | 18:20 |
| jgriffith | smcginnis: you know that 1 month is like 2 griffith-months | 18:21 |
| smcginnis | Hah! | 18:22 |
| ildikov | jgriffith: like this branding while hoping for a Griffith-First-Class on my next flight :) | 18:23 |
| jgriffith | LOL | 18:23 |
| ildikov | mriedem: jgriffith: ok, so we still need to figure out why initialize_connection is called, right? | 18:24 |
| ildikov | if not, then I guess I should just call it a (Mon)day... :) | 18:25 |
| jgriffith | ildikov: yeah, I think so | 18:26 |
| ildikov | shoot; then I go back to read the logs... | 18:26 |
| mriedem | so we got this attachment from cinder in the api RESP BODY: {"attachment": {"status": "reserved", "detached_at": "", "connection_info": {}, "attached_at": "", "attach_mode": null, "instance": "197bb6f9-3410-4fdb-a2a7-88bf97c78e34", "volume_id": "28d1715e-5adc-408b-aaac-bf524fcbd54a", "id": "af2dd524-a945-47d8-b9f0-4b54ab0115f0"}} | 18:27 |

| mriedem | we should be storing that on the bdm | 18:27 |
| mriedem | which goes to the compute for the attach | 18:27 |
| ildikov | yep | 18:29 |
| ildikov | jgriffith: hmmm, I don't recall ever seeing that before | 18:30 |
| mriedem | i have an idea of what's going on | 18:31 |
| pandy | smcginnis: here i have pasted steps trying to do, http://paste.openstack.org/show/662564/, I would like to know whether second or third volume backup is right ? | 18:31 |
| *** itlinux has quit IRC | 18:31 | |
| jgriffith | mriedem: it looks like somethign fails bulding the bdm to me? | 18:32 |
| *** moshele has joined #openstack-cinder | 18:32 | |
| jgriffith | and we don't catch it properly | 18:32 |
| jgriffith | so then when we check that on the update we *think* it's an old style attach | 18:32 |
| * jgriffith wishes he could type better | 18:32 | |
| jgriffith | or even more gooder | 18:32 |
| mriedem | if the bdm.create() or bdm.save() failed, we'd get an exception | 18:32 |
| mriedem | not just ignore it | 18:32 |
| mriedem | nova-api rpc calls to nova-compute reserve_block_device_name, | 18:33 |
| mriedem | which creates the bdm record | 18:33 |
| smcginnis | pandy: It depends what you want to restore. If you just want the full backup restored from step 2, just restore that. If you want the data included in the incremental, then restore that one. | 18:33 |
| mriedem | which is returned to the api | 18:33 |
| *** wN has quit IRC | 18:33 | |
| ildikov | there's an attachment_update call with a response 500: http://logs.openstack.org/57/537957/2/gate/nova-multiattach/456f61e/logs/screen-n-cpu.txt.gz#_Feb_05_15_52_28_186884 | 18:33 |
| ildikov | I might read it wrong though, unsure at this point | 18:34 |
| mriedem | hmm yeah, wth | 18:35 |
| pandy | smcginnis: I have created new volume "test" and did restore of "third" ( latest_incremental_backup) to "test" volume, whether it will have complete backup, I mean both incremental and full ? | 18:36 |
| jgriffith | ildikov: I guess it's better when you point to it :) | 18:36 |
| ildikov | jgriffith: it was my second attempt :) | 18:36 |
| smcginnis | pandy: Yes, it needs to write it all back to be able to restore. | 18:36 |
| jgriffith | I'm confused by all of that in there | 18:36 |
| jgriffith | which is why it seems like the block-device method is honked | 18:37 |
| ildikov | then I have no idea what this is: http://logs.openstack.org/57/537957/2/gate/nova-multiattach/456f61e/logs/screen-n-cpu.txt.gz#_Feb_05_15_52_28_186884 | 18:37 |
| mriedem | so it looks like it's doing a boot from volume here, i'm totally confused | 18:37 |
| mriedem | _prep_block_device only gets called from boot from volume (or unshelve) | 18:38 |
| *** moshele has quit IRC | 18:38 | |
| ildikov | this might as well be the error from the Cinder internal initialize_connection: http://logs.openstack.org/57/537957/2/gate/nova-multiattach/456f61e/logs/screen-n-cpu.txt.gz#_Feb_05_15_52_28_221051 | 18:38 |

| mriedem | shelve isn't involved | 18:40 |
| pandy | smcginnis: really thanks, I have final questions, 1) For Ceph as backend, do we need to pass "--incremental" parameter or by default it will have incremental, If ceph has the feature, how to verify in ceph ? 2) Can we try this in ocata release by changing "https://github.com/openstack/cinder/commit/3e2a593ae9eb80d9753cd118e59008a77a315c11" or supports only from pike release ? | 18:41 |
| ildikov | hmm, I guess it's time to make myself aware of what this whole device tagging thing is doing... | 18:41 |
| *** armaan has joined #openstack-cinder | 18:42 | |
| mriedem | ildikov: it creates 3 volumes, 1 bootable, and then creates a server from those 3 volumes | 18:42 |
| mriedem | with the bootable volume as the root disk | 18:42 |
| smcginnis | pandy: You will need to use --incremental to get an incremental back regardless of backend type. | 18:42 |
| smcginnis | pandy: And yes, I think that commit would need to be backported to Ocata. | 18:43 |
| ildikov | mriedem: I remember some bits and pieces in the code on the tagging part of the whole thing, mostly exceptions and not sure at this point whether that can affect anything in the attach flow? | 18:43 |
| mriedem | tags shouldn't have anything to do with it | 18:43 |
| ildikov | while I agree with you 100%, I was just wondering what can mess up the use of the old vs new flow | 18:44 |
| pandy | smcginnis: thanks, i will do those commit changes in my ocata setup and try that | 18:44 |
| mriedem | ildikov: i've got an idea | 18:44 |
| smcginnis | pandy: Good luck | 18:44 |
| mriedem | ildikov: with boot from volume, we won't call bdm.save() here https://github.com/openstack/nova/blob/master/nova/compute/api.py#L3776 | 18:45 |
| mriedem | because the bdm isn't created in a cell db yet | 18:45 |
| pandy | smcginnis: someone told, ceph has incremental backup, so no need to mention. So asked. How to verify that "incremental"backup has full data while restoring it with new volume ? | 18:45 |
| mriedem | i'm wondering if we're losing the bdm.attachment_id somewhere along the way | 18:45 |
| ildikov | mriedem: ah, that can happen | 18:46 |
| ildikov | we don't call save there as the DB record does not exist at that point | 18:46 |
| pandy | smcginnis: any checksum or LSN or SHA256 can be used to track incremental backup ? | 18:46 |
| jgriffith | You mean like: 18:32 jgriffith| mriedem: it looks like somethign fails bulding the bdm to me? | 18:47 |
| jgriffith | so not bulding it but updating it? | 18:47 |
| jgriffith | That makes sense; and much more likely that a failed update or something slips through than a failure building it | 18:47 |
| openstackgerrit | Sean McGinnis proposed openstack/cinder master: Clear metadata when restoring backup with no metadata https://review.openstack.org/460072 | 18:48 |
| mriedem | req-8007f6e8-2ddf-43c3-9330-c420ccca6361 is the server create request id in the api, | 18:48 |
| pandy | smcginnis: wondering, restoring with latest_incremental_backup_volume with newly created volume will restore all data ?, I felt need to keep full_backup_volume and apply_logs of incremental on top of it while restore ? | 18:48 |
| mriedem | i see the GET calls to get the 3 volumes from cinder, | 18:48 |
| mriedem | but don't see any POST calls to create attachments | 18:48 |
| ildikov | jgriffith: well, when we try to build it it should have the attachment_id, but it gets lost somewhere in the jungle | 18:49 |

| mriedem | i don't see any POST calls to create attachments for these 3 volumes | 18:52 |
| mriedem | from nova-api | 18:52 |
| ildikov | mriedem: I thought we reserve the volume in every case, which means that maybe something went wrong there? | 18:54 |
| ildikov | mriedem: I mean reserve = attachment_create without a connector | 18:54 |
| mriedem | ildikov: i suspect we're getting here somehow https://github.com/openstack/nova/blob/master/nova/compute/api.py#L1344 | 18:57 |
| mriedem | so we don't call reserve or attachment create | 18:57 |
| mriedem | i'll put up a debug patch after lunch | 18:57 |
| mriedem | could be a bug in nova's service version code | 18:57 |

| melwitt | does anyone know what happened to cinder.tests.tempest.api.volume.test_volume_unicode.CinderUnicodeTest? a recent tempest change https://review.openstack.org/#/c/522707 broke the test in the ceph job on stable/ocata but I don't find that the test exists on master. is the test something we should skip on ocata? log http://logs.openstack.org/80/540680/1/check/legacy-tempest-dsvm-full-devstack-plugin-ceph/465f6e2/job-output.txt.gz#_2018- | 19:43 |
| melwitt | 02-04_23_18_37_681552 | 19:43 |
| melwitt | oops http://logs.openstack.org/80/540680/1/check/legacy-tempest-dsvm-full-devstack-plugin-ceph/465f6e2/job-output.txt.gz#_2018-02-04_23_18_37_681552 | 19:44 |
| mriedem | melwitt: it's probably in the cinder repo | 19:46 |
| melwitt | it is back in stable/ocata but on master there's no more tempest/ dir | 19:46 |
| mriedem | http://git.openstack.org/cgit/openstack/cinder-tempest-plugin/ | 19:46 |
| mriedem | queens goal was to move tempest tests from in-repo to plugins | 19:47 |
| melwitt | oh, thanks, there it is | 19:47 |
| melwitt | okay, so it's no longer using the old 'volumes' attribute | 19:47 |

| ildikov | mriedem: might not want to comment on it further... | 20:05 |
| mriedem | we'll see https://review.openstack.org/#/c/540992/ | 20:06 |
| ildikov | mriedem: how that didn't fail before? | 20:06 |
| mriedem | because we fallback to using the old APIs | 20:06 |
| *** itlinux has quit IRC | 20:06 | |
| mriedem | like initialize connection instead of attachment_update | 20:06 |
| ildikov | mriedem: ah yes and that worked... | 20:06 |
| mriedem | right b/c of rolling upgrade that old flow all works | 20:07 |
| ildikov | mriedem: I'm off for two hours now, no wifi on this flight | 20:07 |
| mriedem | so i think what nova-api has been doing all along is checking the nova-compute service version in cell0, which doesn't have any nova-compute services, | 20:07 |
| mriedem | so it just returns 0 | 20:07 |
| mriedem | np, enjoy | 20:07 |
| ildikov | mriedem: what an annoying bug... | 20:07 |
