Fixed In Version:
Doc Type: Bug Fix
Doc Text:
Cause: Cinder's NFS driver contained a bug that prevented the driver from creating a snapshot during volume clone operations, and cloned volumes are used when backing up cinder NFS volumes. Consequence: Cinder NFS volumes could not be backed up. Fix: Cinder's NFS driver bug has been fixed. Result: Backups of cinder NFS volumes work.

OSP15 is EOL, but the fix lives in the newer releases (OSP16) and it has been backported to OSP13.
