#openstack-nova - 2018-12-07
21:07:42 mriedem do the flavors have cpu/ram/disk set to anything !0?
21:07:44 radez oh wait, sry I'm getting my self confused... right so does that log line I just pasted here show that nova is trying to
21:07:46 dansmith radez: what log is this? just nova compute?
21:08:06 radez assign ironic node 3c3eb5ee to nova instance a840afbc?
21:08:34 radez yea nova-compute log
21:08:43 dansmith radez: so probably want to look at the scheduler log
21:09:00 dansmith radez: scheduler is what decides which node it is going to tell compute to use for each instance
21:10:10 radez k lemme find a840afbc in the schedule logs
21:13:17 radez http://paste.openstack.org/show/736844/
21:13:43 openstackgerrit Merged openstack/os-vif master: add isolate_vif config option https://review.openstack.org/612534
21:13:46 radez that also shows a840afbc trying to select 3c3eb5ee
21:14:32 radez hypervisor list incase that's helpful? http://paste.openstack.org/show/736845/
21:14:33 melwitt radez: what version of rocky is this? we had a bug around ironic inventory update in the middle of rocky https://review.openstack.org/593678 but as long as you have 18.0.0.0rc2 or later, you should have the fix for that
21:14:35 melwitt er, at the end of rocky
21:14:42 dansmith radez: can you show more of the log so we can see both?
21:15:07 radez yea, that was just a quick grep, lemme grab more of the scheduler log and check my version
21:16:54 dansmith melwitt: that would only affect nodes in cleaning right?
21:18:11 melwitt dansmith: I don't know, tbh
21:19:14 melwitt I remember there were some ironic driver bugs we fixed near the end of rocky and was curious if those can be ruled out based on what version of rocky they're running
21:19:43 dansmith the only way this should be happening, AFAIK, is if we're not exposing one inventory per node, or somehow not claiming in placement
21:20:15 melwitt yeah, this bug was related to the claiming of a node via setting reserved == total
21:20:36 melwitt and one spot where the newer placement api microversion needed to be set was missed
21:21:00 melwitt so I was thinking that might possible cause a node to not be claimed when it was supposed to. but as for if it only comes up during cleaning, that I didn't know
21:21:20 melwitt *possibly
21:21:57 mriedem radez: what are the values for cpu/ram/disk for the flavors being used for these baremetal nodes?
21:21:58 melwitt I had thought the reserved == total thing was claiming in general and not only for cleaning, but could easily be wrong as I don't know _that_ much about the ironic driver
21:22:11 radez openstack-nova-scheduler-18.0.3
21:22:20 radez ok, got hte version, sry fighting with docker :/
21:22:42 melwitt thanks radez. so yeah, the thing I wondered can be ruled out
21:22:44 dansmith melwitt: reserved=total is only for making the node look unschedulable while being cleaned right?
21:22:55 dansmith melwitt: reserved=total does't make any sense when the node is actually allocated
21:23:30 mriedem i'm wondering if you're hitting https://bugs.launchpad.net/nova/+bug/1796920
21:23:30 openstack Launchpad bug 1796920 in OpenStack Compute (nova) queens "Baremetal nodes should not be exposing non-custom-resource-class (vcpu, ram, disk)" [High,In progress] - Assigned to Matt Riedemann (mriedem)
21:23:31 radez | properties | {u'memory_mb': u'4096', u'cpu_arch': u'x86_64', u'local_gb': u'40', u'cpus': u'4', u'capabilities': u'boot_option:local'
21:23:35 radez both look liek that
21:23:40 mriedem yeah so check that bug
21:23:44 mriedem or https://review.openstack.org/#/c/609043/
21:23:45 radez getting the logs...
21:23:59 dansmith mriedem: yeah, that's the kind of thing I was thinking of
21:24:05 melwitt dansmith: I didn't know that. but what you say makes sense, you're probably right
21:24:06 dansmith mriedem: we consume one CUSTOM_FOO, and then schedule the next one based on there looking like there's ram or something
21:24:22 mriedem i'm very much half assing my involvement here,
21:24:25 mriedem but that's something i'd check out
21:25:45 dansmith I have to leave soon
21:28:24 radez here's more of the scheduler log http://paste.openstack.org/show/736846/
21:31:23 dansmith radez: okay but that's still just one instance, right?
21:31:40 dansmith however, it looks like whatever host it chose got successfully claimed in placement,
21:31:50 dansmith which can't happen if each host is exposing only one inventory item
21:32:32 dansmith radez: can you correlate the "Attempting to claim.." line with the relevant context in the placement log?
21:32:52 radez placement log is the scheduler log?
21:32:57 mriedem no
21:33:00 dansmith nope, a different service
21:33:01 mriedem placement-api log
21:33:12 radez oh, sec lemme find that log
21:33:16 dansmith that should (I think) show you what is being claimed for the instance
21:33:28 dansmith which really should be only one resource, something like CUSTOM_IRONIC_FOO=1
21:34:56 radez would that coorelate on the insance uuid?
21:35:24 dansmith I'm not sure what the string looks like, so not sure if it dumps the consumer (instance) uuid or not
21:35:26 mriedem if the flavor has vcpu/ram/disk, and the compute node is reporting vcpu/ram/disk inventory - which it will be still before stein, the claim will be on vcpu/ram/disk as well
21:35:28 dansmith so I would go by date
21:35:51 dansmith mriedem: wait, what?
21:36:04 dansmith I thought it only reported the old resources in some compat situation?
21:36:06 radez kk
21:37:09 mriedem dansmith: no,
21:37:22 mriedem we didn't neuter the ironic driver until stein, right around the ptg
21:37:26 dansmith I think I recoiled in horror the last time we talked about this
21:37:36 mriedem that's why we needed https://review.openstack.org/#/c/609043/
21:37:49 dansmith so maybe he just doesn't have the resource class in his flavor?
21:39:31 openstackgerrit Matt Riedemann proposed openstack/nova master: Drop pre-cellsv2 compat in compute API.get() https://review.openstack.org/615347
21:39:32 openstackgerrit Matt Riedemann proposed openstack/nova master: Remove "API Service Version" upgrade check https://review.openstack.org/615348
21:39:32 openstackgerrit Matt Riedemann proposed openstack/nova master: Drop old service version check compat from _delete_while_booting https://review.openstack.org/623589
21:39:46 mriedem | properties | {u'memory_mb': u'4096', u'cpu_arch': u'x86_64', u'local_gb': u'40', u'cpus': u'4', u'capabilities': u'boot_option:local'
21:39:54 mriedem those are extra specs?
21:40:03 dansmith no,
21:40:08 mriedem then correct the baremetal flavor doesn't have the custom resource class
21:40:10 dansmith node detaisl Ithink
21:40:52 mriedem radez: have you gone through this? https://docs.openstack.org/ironic/rocky/install/configure-nova-flavors.html
21:41:02 mriedem especially: openstack flavor set --property resources:CUSTOM_BAREMETAL_SMALL=1 my-baremetal-flavor
21:41:15 dansmith and/or.. who created your flavor?
21:41:16 radez http://paste.openstack.org/show/736847/
21:41:48 dansmith o.O
21:42:43 openstackgerrit Matt Riedemann proposed openstack/nova master: Drop old service version check compat from _delete_while_booting https://review.openstack.org/623589
21:42:48 radez jlibosvar created the flavor, it looks like that custom baremetal small is not on it
21:43:13 mriedem CUSTOM_BAREMETAL_SMALL is an example
21:43:14 dansmith radez: it needs to be equal to whatever is set on the node
21:43:18 dansmith right
21:43:25 radez http://paste.openstack.org/show/736848/
21:43:27 mriedem the node has a resource_class field
21:43:34 radez yea lemme see what's on the node
21:43:43 mriedem yeah that flavor isn't going to cut it
21:43:59 dansmith yeah
21:44:03 mriedem https://docs.openstack.org/ironic/rocky/install/configure-nova-flavors.html ftw
21:44:35 radez I don't think there is a resources property on the bm node either
21:44:55 mriedem resource_class
21:45:10 mriedem https://developer.openstack.org/api-ref/baremetal/?expanded=show-node-details-detail#show-node-details
21:45:13 dansmith radez: that "how to configure flavors" doc above is probably your ticket out of here, right?
21:45:21 radez | resource_class | None
21:45:25 mriedem heh "This will be used by the openstack Placement Engine in a future release."
21:45:43 mriedem jroll: maybe we should update the resource_class api-ref parameter description in ironic now...
21:46:17 radez yea maybe he's just missed some of the setup steps. Lemme regroup and try and go back through the steps that have been taken in this env and I'll circle back back next week if we're still haveing trouble
