spotzAnyone still about after the meeting?00:44
flwangspotz: how can i help?00:56
spotzflwang: I'm trying to delete a cluster and it's failing on the deletion of the docker volume. Is there anyway to force it? I'm not sure what will happen if I force the volume deletion00:57
spotzflwang: It's happened twice now, stable/rocky devstack00:58
flwangit's devstack with lvmdriver-1 as voume type, right?00:58
spotzyep00:59
flwangthat's a known issue, and it's most like a nova/cinder issue, and there is no fix yet as far as i can tell01:00
flwangwe haven't seen this with Ceph01:00
spotzIf I force the volume deletion, would the cluster be able to delete or will it fail?01:00
flwangyep01:01
spotzdelete or fail?:)01:01
flwangdelete01:01
spotzOk thanks01:02
flwangno problem01:10
flwangfeel free to ask questions here ;)01:10
spotzWill do:)01:12
spotzflwang: Well it failed again on the cinder volume I'll hit up cinder team in the morning01:17
flwangspotz: wait a sec, let me find the bug for you01:17

openstackLaunchpad bug 1422831 in Magnum "Error on deleting volume on bay update" [High,New]01:18
spotzflwang: Yeah I saw that one earlier, trouble is --docker-volume-size is a required parameter01:19
flwangspotz: use overlay or overlay201:19
flwangfor docker_storage_driver01:20
spotzlooking:) I'm actually trying to teach a lesson on magnum, it's how I find lots of stuff:)01:20

spotzflwang: Ok so if I go back to recreating the template with that parameter and overlay it shpuld work?01:21
spotzflwang: I'll definitely do that, was trying to get this lesson done tonight01:22
flwangit should01:22
spotzflwang: Ok let me give a few things a try:)01:22

brtknrno i answered my own question after investigating a little further09:05
*** salmankhan has joined #openstack-containers09:11
brtknrtobias-urdin: looks like a magnum module for  puppet if I'm not mistaken.... we've built something similar for Ansible at stackhpc:  https://galaxy.ansible.com/stackhpc/os-container-infra/09:36
brtknrwith additional features like adding multiple network interfaces09:36
brtknrsomething i'd like to work towards magnum supporting natively if there's an appetite for it09:37

strigazibrtknr: the infiniband config you want to do can be done only with the config drive? Can it be done with a script after node boot?11:28
*** kaiokmo has quit IRC11:38
*** kaiokmo has joined #openstack-containers11:43
brtknrit can but the config needs to be looked up through neutron and passed, config drive provides a cleaner interface where a readonly drive can be mounted, which cloud-init knows what to do with and automatically configure the interface11:45
strigazibrtknr: I'm trying to understand how you will used, that is why I'm asking.11:46
strigazibrtknr: will you need an extra patch in magnum after this?11:46
brtknrstrigazi: see this https://code.launchpad.net/~brtknr/cloud-init/+git/cloud-init/+merge/35318211:47
brtknrstrigazi: no don't think so11:47
brtknrstrigazi: just supporting what nova and heat already support11:48
brtknrstrigazi: that cloud-init patch knows how to deal with infiniband config passed through config-drive11:54
brtknrstrigazi: we've already been using it for clusters we provision using heat11:55

openstackgerritBharat Kunwar proposed openstack/magnum master: Config drive support for clusters  https://review.openstack.org/61129113:28
brtknrbrtknr: i dont understand why the heat isnt registering config_drive_enabled in the case of swarm_mode...13:29
strigazibrtknr: looking13:29
strigazibrtknr: PS 3 looks ok13:30
brtknrstrigazi: hmmmm....13:34
brtknrstrigazi: how would you debug this?13:37
strigazicheck the stack request sent by magnum to heat13:38
strigazibrtknr: ^^13:38
brtknrstrigazi: when i do `coe cluster show swarm-cd`, it appears to have the right label13:39
strigazibrtknr stack show?13:40
brtknrstrigazi: stack show has wrong label13:40

brtknrstrigazi: think i figured it out! looks like there was an underlying bug14:07
brtknrstrigazi: but would like to hear if you think its a bug14:07
openstackgerritBharat Kunwar proposed openstack/magnum master: Config drive support for clusters  https://review.openstack.org/61129114:09
brtknrstrigazi: look inside magnum/drivers/heat/swarm_mode_template_def.py14:10
*** chhagarw has quit IRC14:12
brtknrstrigazi: label_value was getting value from cluster_template.labels.get(label) instead of cluster.labels.get(label)14:14
*** dims has quit IRC14:16
brtknror perhaps both are needed? except k8s doesnt follow this pattern14:17
*** dims has joined #openstack-containers14:19
strigazibrtknr: labels need to be taken by cluster14:21
strigazibrtknr: not CT14:21
brtknrstrigazi: so you confirm this is a bug?14:26
