Open Stack

Options may be bad, but hardcoded values chosen arbitrarily are worse. Unless someone can justify why the value needs to be 180 and not 179 or 181 then it should be configurable. That's my opinion at any rate.

Subject: [openstack-dev] [nova][cinder] create server from a volume snapshot, 180 reties is sufficient?

hi there:

According to the patch https://review.openstack.org/#/c/80619/, Nova
will wait for volume creation for 180s, the config option is rejected by
Russell and Nikola. But the reason I raise it up is, we found the server
creation failed due to timeout in our deployment, with LVM as Cinder
backend.

So, I wander is 180s really suitable here? Are there some guidences
about when should we add an option? But at least, we should not avoid an
option, just because of the existing overwhelming number of them, right?

Thoughts?
