Bug 980977

Description of problem:

If the storage back end becomes available during volume actions the status in the webUI gets stuck:

test-vol-BZ "stopping gluster volume while creating."	10GB	Error_Deleting

I had to go into the database and manually remove the entries to fix the web UI:

mysql --host=localhost --user=root --password=blah
show tables;
select volumes;
select * from volumes;
select id,host,display_name from volumes
delete from volumes where display_name='test-vol-BZ';

Version-Release number of selected component (if applicable):

openstack-cinder-2013.1.2-3.el6ost.noarch

How reproducible:

I have hit this a couple of different ways so far:

-Power off all gluster nodes during a volume create
-Stop mounted gluster volume, then delete the cinder volume

Steps to Reproduce:
1.  Create a new volume on a glusterfs backend
2.  On the gluster server run:

# gluster volume stop testvol

3.  Attempt to delete the volume from the webUI while the gluster volume is stopped.

4.  Restart the gluster volume:

# gluster volume start testvol

Actual results:

The volume status hangs at error_deleting.  I get an error message in the webUI saying:

You do not have permission to delete volume: test-vol-BZ

Expected results:

I am able to delete the volume after storage comes back up.

Additional info:

I can see this being problematic when there are connectivity issues and/or if there are split brain issues on the gluster back end.
