I think some of the objections to such patches were based on the fact that this is really just a shortcut for two separate operations: create a volume from a Glance image, and then boot off of that image. Instead of monkey-patching it, we should either figure out a way to dynamically configure the timeout based on image size, network conditions, etc, or we should just remove the shortcut entirely, and just have people do the two steps separately (the current workaround for large disk images).

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. -Ben From: Lingxian Kong [mailto:[email protected]] Sent: Tuesday, April 08, 2014 11:59 AM To: OpenStack Development Mailing List 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?
