Srinivas - the compute API never blocks a delete request, unless the server is locked. So by design you can attempt to delete a server in any case where it's unlocked (if you're an admin you can bypass the locked state too). So we aren't going to put a conditional on the delete API such that you can't delete the server while it's being snapshot.
At this point I'm not sure what you're looking for as far as a bug or fix. As noted by Andrey, the compute manager will cleanup the snapshot image in glance if the server was deleted during the snapshot: https://github.com/openstack/nova/blame/15.0.0/nova/compute/manager.py#L3141 https://github.com/openstack/nova/blob/15.0.0/nova/compute/manager.py#L222 ** Changed in: nova Status: New => Won't Fix -- You received this bug notification because you are a member of Yahoo!
