Description of problem:

we had an outage and gluster storage went down
after the storage came back we still had a problem mounting the storage because of a problem in gluster. 
since I did not know we still had a problem I sent detach of volume while the storage was unavailable. 
even after we fixed the issue in the storage, the detach was still stuck 
only after I terminated the instance the detach completed. 

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

openstack-cinder-2013.2-0.9.b3.el6ost.noarch

How reproducible:


Steps to Reproduce:
1. configure cinder to work with glance 
2. boot instance from volume
3. hard shut down gluster so that mount will fail
4. send detach command from UI
5. start gluster 


Actual results:

detach is stuck until we destroy the instance 

Expected results:

we should fail the detach until we can actually send the command or be able to continue the detach once the storage is mounted again.
