Re: [Openstack-operators] NOVA build timeout: Time to fail a vm from build state

Ack. I'm picking my worst case with a 2T volume create and then doubling.

Does anyone have a "good" value they use for this? In my mind it falls
very much into the specific-to-your-cloud-implementation bucket but just
wondered what folks were usign for this setting (if any).

10 minutes would be way longer than I'd want to wait for a build to fail
but that's probably what we will set this to

Hmm, yeah definitely deployment specific. Also, if you're doing boot 
from volume where nova is creating the volume, that's going to add 
additional time depending on the size of the volume, whether the image 
is cached, etc. And there are separate timeouts in the compute manager 
for waiting for the volume to be available for attaching to the server.

[Openstack-operators] NOVA build timeout: Time to fail a vm from build state

[David Medberry]

So, there is a nova.conf setting:

instance_build_timeout (default to 0, never timeout)

Does anyone have a "good" value they use for this? In my mind it falls very
much into the specific-to-your-cloud-implementation bucket but just
wondered what folks were usign for this setting (if any).

10 minutes would be way longer than I'd want to wait for a build to fail
but that's probably what we will set this to
