Instance with status=error and task=scheduling polls forever

[Tres Henry]

In the case that an instance errors during scheduling Horizon continues to poll for updates for that instance forever. Instances with a status of error should probably never be polled because that horse ain't ever gonna get up and go to the races.

This also happens with status=error and task=spawning

That review seems to only have to do with pause/suspend unless I'm missing something?

[Andy Chong (andycjw)]

my mistake, i thought it was the same bug on first look

but if the status=error, the row status would not be 'status_unknown' and the polling should not happen
are you sure that the status=error?

[Andy Chong (andycjw)]

how do i repeat this bug? i tried stopping the nova-scheduler on instance launch, but nothing happens, it just keep building instead of giving me error

[Tres Henry (tres)]

Andy, maybe try stopping libvirt (sudo service libvirt-bin stop) in the middle of spawning? Or you can just tweak the instances table in the nova mysql db directly.

[Andy Chong (andycjw)]

i tried launching an extra large 16GB instance that will fail on scheduling, is this the same?
if it is, i think i know what's wrong, it's actually not polling, just the animation of spinning circle
please check your webserver it's probably not getting hit
