Salman, The location for the locks is determined by the --lock_path setting in nova.conf. This is apparently set to the base path where the nova python code lives ($pybasedir) in devstack:
2012-04-14 21:35:42 DEBUG nova.service [-] lock_path : /opt/stack/nova from (pid=3700) wait /opt/stack/nova/nova/service.py:442 Since, that directory has a bunch of important files in it, certainly don't follow my previous advice and remove all the files in that directory. There is a bug (https://bugs.launchpad.net/nova/+bug/785955) about nova not cleaning up locks that should have been fixed in essex-4. As part of the fix to that Mike Pittaro wrote a cleanup locks script that should be in /opt/stack/nova/tools/clean_file_locks.py. Try running that and let us know if that fixed it. If not look for *.lock files in /opt/stack/nova Thanks, Nate On Sat, Apr 14, 2012 at 9:07 PM, Salman Malik <[email protected]> wrote: > Thanks Nate for the quick reply. > There is no such directory on the system (I am using devstack if that > helps...) > > Thanks, > Salman > > ________________________________ > Date: Sat, 14 Apr 2012 21:00:39 -0400 > Subject: Re: [Openstack] nova-network service stuck > From: [email protected] > To: [email protected] > CC: [email protected] > > > Check in Nova's lock dir, on my system it's /var/lib/nova/tmp.
