X-Git-Tag: ses5-milestone5~364^2~6
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=2f4cb26d8bbd1457bc261547103b56ad40b3c464;p=ceph.git

qa/workunits/rbd: exercise snapshot renames within rbd-mirror test

Snapshot rename operations utilize the (cluster) unique snapshot
sequence to prevent attempts at replays. When mirroring to a
different cluster, these sequences will not align.
