Out of curiosity - which version of CEPH ? I've read that I/O to RBD
images for which snapshots exist is impacted. Is that your experience ?
And, do you maintain the snapshots, or are they discarded after (i.e.:
are they used as potential point-in-time recovery points, or are they
used to take a backup, then discarded ?)
Cheers,
