| tommylikehu | Hey geguileo , not sure about your comment here: https://review.openstack.org/#/c/498283/1/cinder/db/sqlalchemy/api.py :) | 11:01 |
| geguileo | tommylikehu: why would you unnecessarily change the order? | 11:03 |
| tommylikehu | geguileo: oh I need to collect the resources from the reservation records | 11:06 |
| geguileo | tommylikehu: well, I believe we should lock on the quota usages before going into the reservations... But I haven't digged all that much into the quota stuff | 11:07 |
| geguileo | tommylikehu: because I consider it to be a CF | 11:08 |
| tommylikehu | what is CF | 11:08 |

| *** markvoelker has joined #openstack-cinder | 11:15 | |
| tommylikehu | geguileo: ok, I think that statement would block if either quota usage or resvervations is locked by other request, so the order should not matter. But anyway I agree with your last words. | 11:16 |
| geguileo | it would block, but wouldn't you get into a deadlock if other parts of the code are locking in the reverse order? | 11:16 |
| geguileo | and is the lock from _get_quota_usages locking on the query itself or the results? | 11:19 |
| geguileo | because if it's the results then by the time you do the lock on quota usages there could be new reservations | 11:19 |
| tommylikehu | geguileo: it's possible, so it would be better to add a new get_reservation method without lock for such a case like this. we only needs the resource key here, right? | 11:24 |
| geguileo | tommylikehu: no idea | 11:24 |

| itlinux | hello all.. I have a question on cinder in a tripleo env.. the iqn is presented through the controller and the flash storage I have does not present the volume to the compute node.. now if I use the lvm drivers then the volume gets created on pcs (volume storage) and it does expose that to the compute node and I can attach the volume no problems at all.. | 18:24 |
| *** diablo_rojo has quit IRC | 18:39 | |
| smcginnis | itlinux: Can you explain what you mean by "the iqn is presented through the controller"? | 18:42 |
| *** diablo_rojo has joined #openstack-cinder | 18:42 | |
| itlinux | hi I see the iqn in the controller but not in the compute node.. let me open the logs and post it now | 18:43 |
| smcginnis | itlinux: I'm just not sure what you mean by "in the controller" | 18:43 |
| itlinux | the controllers nodes.. | 18:44 |
| itlinux | smcginnis http://paste.openstack.org/show/619663/ | 18:45 |
| smcginnis | Hmm, only time an external volume should be visible on the cinder node is if it is copying an image to the volume. | 18:47 |
| smcginnis | Then it should unmap it and map it to the nova compute node. | 18:47 |
| smcginnis | patrickeast: It says pure in the paste. And ideas? :) | 18:47 |
| itlinux | yea it's a pure storage flash drives.. | 18:47 |
| itlinux | so not sure why this .. because the config is pretty easy.. | 18:48 |
| itlinux | like 5 lines | 18:48 |
| *** eharney has joined #openstack-cinder | 18:48 | |
| *** armax has quit IRC | 18:53 | |
| smcginnis | itlinux: Well, maybe he'll show up with some ideas. Any tracebacks in the nova logs? | 18:54 |
| * patrickeast catches up | 18:55 | |
| itlinux | well nova in the compute node that's what shows.. and then it fails | 18:55 |
| itlinux | since the lun does not exist | 18:55 |
| *** lpetrut has quit IRC | 18:56 | |
| smcginnis | itlinux: Pretty sure there would be more logs before the message. :) | 18:56 |
| itlinux | let me paste them all | 18:56 |
| patrickeast | itlinux: more logs would definitely help | 18:57 |
| itlinux | yes working on this now | 18:57 |
| patrickeast | it looks like the volume was attached to a controller at some point, but maybe didn't get cleaned up correctly | 18:57 |
| patrickeast | what version of openstack is this? | 18:58 |
| patrickeast | itlinux: ^ | 18:58 |
| itlinux | http://paste.openstack.org/show/619667/ | 18:59 |
| itlinux | ocata | 18:59 |
| itlinux | it's RDO | 18:59 |
| itlinux | sorry Tripleo RDO | 18:59 |
| itlinux | HA | 18:59 |
| itlinux | trunk | 19:00 |
| itlinux | passed version of ci | 19:00 |
| itlinux | I enabled multipath as well since you I was testing it with and without to see why it was failing.. | 19:01 |
| itlinux | strange enough is that multipath -ll does not show me anything | 19:01 |
| *** adisky__ has quit IRC | 19:02 | |
| patrickeast | have you verified that you can manually attach a volume to the nodes? | 19:04 |
| patrickeast | like, openstack aside, following the normal attach process for a pure iscsi volume | 19:04 |
| *** catintheroof has quit IRC | 19:04 | |
| patrickeast | i'd be curious to see if we can isolate the issue more | 19:04 |
| patrickeast | if that doesn't work then no amount of openstack config or bug fixes are going to help | 19:05 |
| itlinux | yes I can do this on the compute node | 19:05 |
| itlinux | http://paste.openstack.org/show/619668/ | 19:05 |
| itlinux | manually created the pure | 19:05 |
| patrickeast | and the multipath device shows up? | 19:05 |
| patrickeast | that seems to be the kicker | 19:05 |
| itlinux | if I do this http://paste.openstack.org/show/619669/ | 19:06 |
| patrickeast | gotcha, so what is under /dev/ ? is there a /dev/mapper associated with it? or a /dev/dm-X path? | 19:08 |
| patrickeast | let me go look at one of my centos test nodes really quick and do the same thing (manual attach one iscsi volume), we can compare the device configs and behavior | 19:09 |
| itlinux | ok let me check | 19:09 |
| itlinux | super | 19:09 |
| itlinux | thanks patrickeast: | 19:10 |

| x0ff | smcginnis: this one is from ocata | 20:13 |
| smcginnis | x0ff: OK, good. At least it's something recent. :) | 20:14 |
| smcginnis | x0ff: Anything in the Cinder logs giving any hints? | 20:14 |
| x0ff | smcginnis: nothing suspicious. | 20:14 |
