| stevemar | patrickeast: thanks for reviewing1 | 01:16 |
| stevemar | ! | 01:16 |
| stevemar | patrickeast: we (the osc team) has been looking for feedback on how to implement the manage bits | 01:17 |
| stevemar | patrickeast: if you could find the time to review https://review.openstack.org/#/c/363574/ i'd be oh so grateful | 01:17 |
| stevemar | patrickeast: some of the reasoning for adding this to "create" is there | 01:18 |
| stevemar | patrickeast: i'm still not sure if this is the more user friendly approach, but that's why i'm bugging you folks :) | 01:19 |
| patrickeast | stevemar: sounds good, i'll check it out | 01:19 |
| *** sdake_ has joined #openstack-cinder | 01:19 | |
| patrickeast | stevemar: happy to look at this stuff, just hadn't really been on my radar until now | 01:19 |
| stevemar | patrickeast: that's cool, we more or less implemented all the "easy" stuff | 01:20 |
| stevemar | patrickeast: it's the funny stuff, like encryption and manage that we're catching up on, and desperately need input for :) | 01:20 |

| patrickeast | much less on a cli | 01:21 |
| stevemar | patrickeast: yeah... unmanage has a {} payload :) | 01:21 |
| patrickeast | stevemar: haha exactly | 01:21 |
| stevemar | patrickeast: i did a <blink> twice | 01:21 |
| *** sdake has quit IRC | 01:21 | |
| patrickeast | stevemar: oh, "manage and unmanage are not appropriate action names" is there like a specific list of appropriate ones? | 01:23 |
| *** ducttape_ has joined #openstack-cinder | 01:23 | |
| stevemar | patrickeast: http://docs.openstack.org/developer/python-openstackclient/commands.html#actions | 01:24 |

| *** zouyapeng has quit IRC | 01:25 | |
| patrickeast | stevemar: ok cool that makes sense | 01:25 |
| stevemar | patrickeast: to be fair, i'm not sure why manage/unmanage are not appropriate :) | 01:25 |
| patrickeast | stevemar: hehe yea i guess compared to the nova specific ones it seems like fair game, surely we aren't the only crazy project that does this kind of import/export action | 01:26 |
| patrickeast | oh well | 01:26 |
| stevemar | patrickeast: actually.... haven't seen any other project do it yet >.< | 01:27 |
| patrickeast | stevemar: dang, maybe i'll go do it somewhere else... export .. uh.. glance image or something | 01:27 |

| gus | I have a kubernetes-using-cinder bug that I need help with: From inside the guest, how can I work out which /dev block device corresponds with which attached volume? | 07:14 |
| gus | The bug report is https://github.com/kubernetes/kubernetes/issues/33128 and suggests using /dev/disk/by-id/virtio-$truncated_cinder_uuid | 07:15 |

| aohuanxuan | HI everyone, I have one question about "cinder backup reset-state" command, we can see we can set the "error" status for a back by this command, does we really need "error" state? when will we need to set a backup to "error"? | 12:13 |
| *** Lee1092 has quit IRC | 12:14 | |
| *** ManishD has quit IRC | 12:15 | |
| dulek | aohuanxuan: I can imagine a situation when some c-api->c-bak messages are lost in RabbitMQ and backup hangs in "creating". Admin would want to set the backup into error state. | 12:15 |
| scottda | aohuanxuan: The 'reset-state' command is a way for the admin to manipulate the Cinder DataBase using the API. Several states are available. Perhaps a backup is in a transitional state and the admin wishes to set it to 'error' for some reason. | 12:16 |
| *** ducttape_ has joined #openstack-cinder | 12:17 | |
| TommyLikeHu_ | scottda: could you spend some time to take a review over this volume type filter's bp:https://review.openstack.org/#/c/367110/, much appreciated | 12:18 |
| scottda | TommyLikeHu_: It looks like the spec is not merged yet, and a Cinder core has a -1 on the spec. You should address the comments on the spec first, and work on getting the spec merged. | 12:20 |
| openstackgerrit | guangpei.liu proposed openstack/cinder: Remove unnecessary setUp https://review.openstack.org/374101 | 12:21 |
| TommyLikeHu_ | scotta:I have talked with zhiteng early,he said it's ok to pull my codes | 12:22 |
| TommyLikeHu_ | ping winston-d | 12:22 |
| aohuanxuan | dulek, scottda: Oh, get it! Thank you very much! I am implementing the "backup reset state" function in OpenStackClient, thanks again for your explanation :) | 12:22 |
| TommyLikeHu_ | scotta: sorry push | 12:23 |

| pkoraca | Hi, one potentially stupid question about Cinder :) If ie. IBM Storwize is used as Cinder backend - does then VM connect via iSCSI directly to storage? So if it's directly, Cinder service should not use much network bandwidth and can be deployed ie. on Controller instead of using separate physical nodes? | 14:36 |

| smcginnis | pkoraca: Cinder does not get involved in the data path, just the control path. | 14:43 |
| smcginnis | pkoraca: So it should not have high bandwidth needs. | 14:43 |

| openstack | The meeting name has been set to 'cinder_testing' | 15:08 |
| smcginnis | o/ | 15:08 |
| scottda | Anyone want to jump in with something about tests? | 15:09 |
| smcginnis | scottda: One thing to mention... | 15:09 |
| smcginnis | I used your Newton etherpad as a basis to start one for Ocata | 15:09 |
| scottda | cool | 15:09 |
| xyang1 | hi | 15:09 |
| smcginnis | #link https://etherpad.openstack.org/p/cinder-ocata-testing Testing tracking | 15:09 |
| scottda | I put something on the Summit agenda to give status on this group, but only has a link to the etherpad at this point. | 15:10 |
| *** alonma has joined #openstack-cinder | 15:10 | |
| smcginnis | Great | 15:10 |
| akerr | o/ | 15:10 |
| scottda | #link https://etherpad.openstack.org/p/ocata-cinder-designsummit-planning | 15:10 |
| scottda | Please feel free to add specifics to that item (L#37) | 15:11 |
| erlon | ok | 15:12 |
| scottda | I also mentioned that "We started focussing on testing and started weekly test working group meetings" in the Newton retrospective | 15:13 |
| scottda | #link https://etherpad.openstack.org/p/cinder-newton-retrospective | 15:13 |
| erlon | scottda: it would be good to have a session to discuss what we want to plan to test in this cicle | 15:13 |
| scottda | It would be nice if others had more detailed feedback about testing efforts | 15:13 |
| *** andymaier has quit IRC | 15:14 | |
| *** alonma has quit IRC | 15:14 | |
| scottda | erlon: Yes, well, hopefully people will come ready to volunteer to write tests, etc. We are already pretty good at identifying things that need doing. The hard part is actually doing it. | 15:14 |
| *** dustins has quit IRC | 15:15 | |
| *** dustins has joined #openstack-cinder | 15:15 | |
| erlon | scottda: mhm, just so people know, Ill keep some time from now working on this, and mainly on infra scripts, so, any suggestion are welcomed | 15:16 |
| smcginnis | Please add anything to the testing etherpad. | 15:16 |
| erlon | scottda: I stared with the multibackend job for migration/retype, as soon I have patches ill let you guys know | 15:16 |
| smcginnis | Hopefully we can build that up to cover what needs testing and who is working on it so we can get a good sweep for Ocata. | 15:17 |
| scottda | erlon: That work is already underway... | 15:17 |
| scottda | #link https://review.openstack.org/#/c/195443/ | 15:17 |
| erlon | scottda: you mean the migration/retype between all open backends? | 15:17 |
| scottda | #link https://review.openstack.org/#/c/326681/ | 15:17 |
| scottda | erlon: OH, that. No, that is different. | 15:18 |
| erlon | scottda: those tempest tests will be very nice to have running in the multi-matrix job | 15:18 |
| scottda | erlon: I think you added the items at L#71? Could you add your name to that, please. | 15:18 |
| erlon | scottda: yes | 15:19 |
| scottda | Yes, I have it on my schedule today to work on getting them moved to multi-node, multi-backend. Still not sure the details of how to do that, or if it will even work with LVM | 15:19 |
| erlon | scottda: theres are some patches on the way implementing the multibackend for LVM | 15:20 |
| erlon | mine are lines 76 trough 81 | 15:20 |
| scottda | Yes, but needs to be moved to multi-node to get it to call Nova's swap_volume() | 15:20 |
| bswartz | anyone know if cinder meeting is happening today? | 15:21 |
| scottda | bswartz: We've an agenda, so I reckon so. | 15:22 |
| erlon | scottda: mhm, actually I think that this scenario will be covered in the multi-backend matrix MN | 15:22 |
| smcginnis | bswartz: Yes | 15:22 |
| bswartz | k | 15:22 |

| *** EinstCrazy has joined #openstack-cinder | 15:24 | |

| scottda | s/no/know | 15:24 |
| *** alonma has joined #openstack-cinder | 15:24 | |
| erlon | scottda: can we merge the TODO list under the deployment sections? it is a bit confising the way it is | 15:24 |
| smcginnis | bswartz: Yeah, Wednesday's always seem to be a challenge there. :) | 15:25 |
| erlon | scottda: or better, a TODO under each deployment | 15:25 |
| smcginnis | Hopefully we can make it quick. | 15:25 |

| hemna | anyone using xenial as a vagrant (libvirt provider) ? | 16:50 |
| smcginnis | skamalakannan_: Everyone's favorite error message. | 16:50 |
| smcginnis | skamalakannan_: Unfortunately you will need to look through the logs to see why all hosts were filtered out. | 16:50 |
| geguileo | hemna: You mean in the host or the guest? | 16:50 |
| hemna | guest | 16:50 |
| geguileo | hemna: I am | 16:51 |
| hemna | I'm having a hard time getting vagrant up to ssh into the guest | 16:51 |
| geguileo | for the replication tests | 16:51 |
| hemna | it never seems to get a network | 16:51 |
| patrickeast | I use it with OpenStack+libvirt+vagrant | 16:51 |
| geguileo | hemna: Which box are you using? | 16:51 |
| hemna | I'm using packer to build a nightly box with the stock ubuntu 16.04 iso | 16:52 |
| geguileo | hemna: With yk0/ubuntu-xenial it seems to work | 16:52 |
| scottda | hemna: They changed the nic name in xenial. Could that be the problem? eth0 -> something_I_cannot_remember | 16:52 |
| *** e0ne has quit IRC | 16:52 | |
| hemna | bah | 16:52 |
| scottda | eth0 -> ens33 | 16:53 |
| hemna | witf is that | 16:53 |
| * hemna smacks canonical in the head | 16:53 | |
| patrickeast | all of em are named ens now | 16:53 |
| patrickeast | similar to like centos and others have been | 16:53 |
| scottda | What, shouldn't cause any problems? Why not just change it every release :) | 16:54 |
| skamalakannan_ | any clues smcginnis | 16:54 |
| patrickeast | hemna: so speaking of xenial, i have been digging more into the issues and enlisted some additional help from folks on our team that are the iscsi guru's | 16:55 |

| patrickeast | hemna: there were a few issues that i was hitting related to udev rule changes and some updates needed on my test array, but the disappearing /dev/mapper/<id> path still persists | 16:55 |
| geguileo | Anybody familiar with the replication stuff? Specificallly the detach of an in-use volume after the failover to reattach it | 16:56 |
| patrickeast | hemna: one thing that came out of the discussion though was a question as to why we are rebuilding the multipath map before detaching | 16:56 |
| hemna | patrickeast, ok. this is why I'm trying to stand up xenial, so I can hack on this | 16:56 |
| patrickeast | hemna: turns out that is a weird thing to do | 16:56 |
| hemna | the multipath -r ? | 16:56 |
| patrickeast | yea | 16:56 |
| patrickeast | i looked back, and traced its origins to https://github.com/openstack/cinder/blame/24d7e244133ddb46fc3de79b8222424db21672d1/cinder/brick/initiator/connector.py#L341 | 16:57 |
| patrickeast | havn't figured out yet where it came from before that, maybe over in nova | 16:57 |
| hemna | that could have come from the old Nova iscsi code | 16:58 |
| hemna | when I added that there | 16:58 |
| patrickeast | but current thinking on our side is that its probably not needed, and if anything is going to cause problems (as seen in xenial) | 16:58 |
| patrickeast | any recollection from eons past as to why it was added? | 16:58 |
| patrickeast | or just a thing we do, has been and always will be? | 16:58 |
| hemna | patrickeast, https://github.com/openstack/nova/blob/kilo-eol/nova/virt/libvirt/volume.py#L605 | 16:59 |
| hemna | yah it came from the nova code originally | 16:59 |
| ckonstanski | To turn off the BS "pedictable network names" without touching the kernel command line, touch the following two files in /etc/udev/rules.d/: 80-net-name-slot.rules 80-net-setup-link.rules | 16:59 |
| ckonstanski | You probably only need one of those, but I'm not sure which. | 17:00 |
| ckonstanski | Then you'll be back to eth0 | 17:00 |
| hemna | xyang1, did it! :P | 17:00 |
| patrickeast | ah ha! | 17:00 |
| patrickeast | well wait, that patch just moved where it was | 17:00 |

| *** kaisers_ has quit IRC | 17:03 | |
| *** krtaylor has joined #openstack-cinder | 17:04 | |
| patrickeast | hemna: so i guess it came from here https://github.com/openstack/nova/commit/933365a583daa5b9eabcf2397c3e7b803e7af74c | 17:06 |
| hemna | https://github.com/openstack/nova/commit/933365a583daa5b9eabcf2397c3e7b803e7af74c | 17:06 |
| hemna | oh hehe | 17:06 |
| hemna | yah | 17:06 |
| hemna | the original multipath addition to iscsi | 17:07 |
| patrickeast | ima try taking it out and bang on things to see if anything breaks | 17:07 |
| hemna | ok | 17:07 |
| xyang1 | hemna: what did I do?:) | 17:08 |
| *** kumarb has quit IRC | 17:09 | |
| hemna | heh nothing. | 17:09 |
| scottda | xyang1: I'd approve your functional tests for groups if you think it's a bad idea to share code as I asked in the comment to https://review.openstack.org/#/c/362584 | 17:10 |
| *** ociuhandu has quit IRC | 17:10 | |
| scottda | xyang1: I can go either way, just wondering what you think? | 17:10 |
| xyang1 | scottda: not a bad idea. I think we can share the code | 17:10 |
| xyang1 | scottda: do you mind merge this patch and I'll submit another one soon to reduce duplicate code? | 17:11 |
| *** diablo_rojo has quit IRC | 17:11 | |
| scottda | xyang1: sure, I'll approve now. | 17:11 |
| xyang1 | scottda: not just group, group snapshot, volume also uses similar code | 17:11 |
| xyang1 | scottda: thanks! | 17:12 |
| scottda | xyang1: Thanks for the tests. | 17:12 |
| *** jungleboyj has quit IRC | 17:12 | |
| xyang1 | scottda: good to have them to prevent regression | 17:12 |
| hemna | patrickeast, so, maybe the multipath -r is just taking a while to rebuild the map | 17:13 |
| hemna | and in the mean time the /dev/mapper/<WWN> goes away | 17:13 |
| *** akapil has quit IRC | 17:14 | |
| patrickeast | hemna: maybe, i tried putting in a wait for path thingy and it still fails | 17:17 |
| patrickeast | seems like it wont come back until another rebuild comes back, leads me to believe that something might be wrong with this version of multipath-tools | 17:18 |
| patrickeast | but if we don't need to rebuild it (or rather, shouldn't really be doing it ourselves) the problem kinda goes away | 17:18 |
| * patrickeast wants to believe its that easy | 17:19 | |
| *** akapil has joined #openstack-cinder | 17:20 | |

| erlon | flip214: I just press ENTER and it continues, but, Im wondering how it pass in the gate job? | 19:00 |
| openstackgerrit | Merged openstack/cinder: Add functional tests for groups https://review.openstack.org/362584 | 19:00 |
| flip214 | erlon: I guess that in the gate there's no TTY, and the default answer is YES. | 19:00 |
| erlon | flip214: hmmh | 19:01 |
| flip214 | don't think that I want to pass that argument, though | 19:01 |
| flip214 | it's not bad, asking for confirmation | 19:01 |
| flip214 | perhaps I even did test that and decided that way, on purpose... | 19:01 |
| flip214 | too long ago | 19:01 |
| erlon | flip214: I don't think is a problem if its passing | 19:02 |
| erlon | flip214: maybe its because Im not running in the gate | 19:02 |
| erlon | flip214: anyways, im trying to run drbd along with the other open backends, ill possible ping you if I find any problem | 19:03 |

| erlon | flip214: ok, I hit a problem in the first attemp (lost the log :/ ), but know Im running only with drbd enabled to see if happens again | 19:06 |
| erlon | flip214: I talk to you or him tomorrow if needed | 19:07 |
| flip214 | it's a her, but never mind ;) | 19:09 |

| jungleboyj | Hey, snapshot questions. | 20:23 |
| jungleboyj | eharney: Can I bother you for a few. | 20:23 |
| eharney | jungleboyj: sure | 20:24 |
| jungleboyj | So, I am on libvirt 1.2.12 | 20:24 |
| jungleboyj | I can create snapshots for both attached and unattached disks. | 20:25 |
| jungleboyj | When I try to go and delete the snapshots, however, it all goes wrong. | 20:25 |
| jungleboyj | I can't delete any of the snapshots. | 20:25 |
| *** alonma has quit IRC | 20:26 | |
| eharney | what kind of error occurs? | 20:26 |
| jungleboyj | Cinder calls off to nova it appears and then it sits waiting for the snapshot to go away. Looping endlessly. | 20:27 |
| jungleboyj | On the Nova side it isn't clear what is happening.

| jungleboyj | Yikes, sorry, that was more than I realized. | 20:29 |
| jungleboyj | Sorry. | 20:29 |
| eharney | this sounds vaguely like a familiar bug... is this on master? | 20:29 |
| jungleboyj | Yes. | 20:29 |
| eharney | i seem to remember a this being raised, looking for a bug now | 20:30 |
| jungleboyj | It says waiting for blockRebase job completion | 20:30 |
| eharney | well that's probably good, because it means it's at least trying to do the deletion in libvirt | 20:31 |
| eharney | can you look at "virsh blockjob" output for that instance? | 20:31 |
| jungleboyj | Looking. | 20:31 |
| *** alonma has quit IRC | 20:34 | |
| eharney | ah, the "skipping... as it is a volume" log makes sense | 20:35 |
| eharney | i think that's just Nova recalculating space usage etc | 20:35 |
| jungleboyj | eharney: What do I give for the path? | 20:35 |
| eharney | i think you want "vdb" etc for the path, and to also give "--info" | 20:37 |
| jungleboyj | Says no current block job for vdb | 20:38 |
| jungleboyj | The snapshot I am trying to delete isn't attached to anything though. | 20:38 |
| eharney | oh, well, if the volume isn't attached then it will just be done in c-vol | 20:39 |
| eharney | and libvirt doesn't matter | 20:39 |
| jungleboyj | Hold on, so the volume that was snapshotted is attached. Snapshot itself is not. | 20:40 |
| jungleboyj | Let me try somethin ghere. | 20:41 |
| eharney | oh right | 20:41 |
| *** coolsvap has quit IRC | 20:42 | |
| eharney | so no blockjob is running now, but the snap is stuck in "deleting"? | 20:42 |
| *** mriedem has quit IRC | 20:43 | |
| jungleboyj | Ok, so I can delete it if the associated volume isn't attached. So, that is good. | 20:44 |
| *** crose has quit IRC | 20:44 | |
| eharney | yeah, but that's the simple case :) | 20:45 |
| jungleboyj | Ok, so let me get back to the state where it is stuck deleting. | 20:45 |
| *** rlrossit has quit IRC | 20:46 | |
| *** mriedem has joined #openstack-cinder | 20:48 | |
| jungleboyj | eharney: Still no current block job | 20:48 |
| eharney | jungleboyj: it could be that the block job is finishing immediately if there's no data written to the snap... you may need to turn on libvirtd debug logs to see it | 20:49 |
| eharney | jungleboyj: but better to check the instance vs the json file | 20:49 |
| eharney | jungleboyj: look at "virsh dumpxml" for that domain and compare that to what's in the volume-1234.json file | 20:50 |
| jungleboyj | I didn't do anything to change the file. | 20:51 |
| eharney | well, Cinder updates it when the snap delete is done | 20:51 |
| eharney | but i'm thinking it never got the indication from Nova that Nova was finished | 20:52 |
| jungleboyj | You going to be on for a little bit longer? Coffee shop is closing. | 20:52 |
| eharney | i should be yeah | 20:53 |
| jungleboyj | eharney: ^^ | 20:53 |
| jungleboyj | Ok, I will be back on in 30 or so. | 20:53 |

| jungleboyj | eharney: Will this not work if there isn't a guest agent running in the instance? | 22:03 |
| eharney | jungleboyj: it doesn't require the guest agent, if the call w/ quiescing fails, it just calls again w/o quiescing requested | 22:03 |
| eharney | but that's all in the create path, i don't think you were having issues there | 22:04 |
| jungleboyj | eharney: Right. I was just trying to follow this from the beginning. | 22:04 |
| eharney | i have to run for a while | 22:05 |
| jungleboyj | eharney: Ok. This is weird. I don't see anywhere that the delete makes it to nova. I just see the periodic job over and over. | 22:07 |

| patrickeast | hemna: hah, i just noticed that the version of multipath-tools on 16.04 (0.5.0) was tagged upstream 2 years ago? http://git.opensvc.com/gitweb.cgi?p=multipath-tools/.git;a=tags | 22:20 |
| hemna | 2 years ago | 22:20 |
| hemna | damn | 22:20 |
| hemna | what's 14.04 been stuck on then ? | 22:20 |
| patrickeast | uhh i think 4.8 or 4.9 iirc | 22:21 |
| patrickeast | hemna: http://packages.ubuntu.com/trusty-updates/admin/multipath-tools | 22:21 |
| patrickeast | 4.9 | 22:21 |
| patrickeast | circa 2010, good year for multipathing i guess | 22:22 |
| *** xyang1 has quit IRC | 22:22 | |
| patrickeast | hemna: so far pulling out multipath -r calls everywhere (where we don't have a decent reason to do it) seems to do the trick | 22:23 |
| patrickeast | and nothing is breaking | 22:23 |
| hemna | well that's good! | 22:23 |
| patrickeast | i still don't like that I don't know *why* it was breaking... but i've lived with worse sins | 22:23 |
| hemna | I'm just now getting a xenial vagrant working | 22:23 |
| hemna | PITA | 22:23 |
| patrickeast | yea seriously | 22:24 |
| patrickeast | took me like a week to get my ci nodes running : / | 22:24 |
| patrickeast | just a blank cloud image works pretty well, but all the provisioning stuff was different jussssttt enough to break all kinda of stuff | 22:24 |
| hemna | the networking has been a pita | 22:25 |

| patrickeast | hemna: ^ will be fun to see what other folks think of that, no idea if any other storage backends need it... | 22:33 |
| hemna | I don't think any of our CI's are using multipath fwiw | 22:34 |
| hemna | :( | 22:34 |
| hemna | I've asked for quite a while | 22:34 |
| hemna | nope | 22:34 |
| patrickeast | dang, iirc one of the emc ones and maybe netapp or someone else did it | 22:34 |
| patrickeast | so maybe we'll get some coverage | 22:35 |
| *** ducttape_ has quit IRC | 22:36 | |

| patrickeast | oh 16.04 has multipathd service now | 22:37 |
| patrickeast | take a look at 'systemctl | grep multi' | 22:37 |
| hemna | it's running | 22:37 |
| hemna | I bounced it too | 22:37 |
| hemna | nothing in /dev/mapper | 22:38 |

| hemna | patrickeast, so, I got multipath to work | 23:11 |
| hemna | patrickeast, I attached, then detached, all is fine | 23:11 |
| hemna | patrickeast, then I attached and ran multipath -r | 23:11 |
| hemna | roasted the map | 23:11 |
| *** Julien-zte has joined #openstack-cinder | 23:11 | |

| openstackgerrit | John Griffith proposed openstack/cinder: Provide cfg to ignore lvm descriptor leak warnings https://review.openstack.org/365167 | 23:11 |
| hemna | I re-attached, and it puked | 23:11 |
| hemna | I had to bounce multipathd for it to get fixed. | 23:11 |
| patrickeast | Yay, I'm not crazy | 23:12 |
| hemna | running multipath -r nukes everything | 23:12 |
| hemna | the /dev/mapper/<wwn> entries vanish | 23:12 |
| hemna | and never come back | 23:12 |
| patrickeast | If you do it again they might come back, did for me | 23:12 |
| hemna | yah it does | 23:13 |
| patrickeast | But when they came back they weren't symlinks to like dm-X anymore | 23:13 |
| hemna | the multipath db gets hosed and in a strange state the first time. | 23:13 |
| hemna | patrickeast, yup, I just noticed that too | 23:13 |
| hemna | the /dev/mapper entry wasn't a symlink | 23:13 |
| hemna | man what a CF | 23:13 |
| patrickeast | Weirdly enough you can still write to it and stuff | 23:14 |
| hemna | bad xenial | 23:14 |
| hemna | ok well, I presume this still works in Trusty | 23:14 |
| hemna | by removing the -r call | 23:15 |
| patrickeast | The other thing is that I think its just that dev/mapper path, the dm-X device sticks around | 23:15 |
| patrickeast | Yea looked like it | 23:15 |
| hemna | we should be calling multipath -f /dev/X later on | 23:15 |
| hemna | and that should nuke the dm-X stuffs | 23:15 |
| patrickeast | Right before I walked out of the office (on mobile now) I saw my parallel tempest run on denial fail to logout of a session... So still something funny going on | 23:16 |
| hemna | :( | 23:16 |
| patrickeast | Single threaded everyone is happy, multi on trusty seems good too | 23:16 |
| hemna | ok i'm heading out. | 23:17 |
| hemna | I'll have a little bit of time tomorrow to hack some more | 23:17 |
