Title:
powervm error'd local volume cleanup fails
Status in OpenStack Compute (Nova):
Fix Released
Bug description:
During spawn, if a local volume for the backing block device fails to
be created, the cleanup operation for the volume can fail with a
"UnboundLocalError: local variable 'disk_name' referenced before
assignment" error.
The fix is to assign to disk_name earlier and check for None before
running cleanup.
