Its my understanding that pool snapshots would basically require us to be in a all or nothing situation were we would have to revert all RBD's in a pool. If we could clone a pool snapshot for filesystem level access like a rbd snapshot, that would help a ton. Thanks, Adam Boyhan System & Network Administrator MEDENT(EMR/EHR) 15 Hulbert Street - P.O.

Den tors 30 jan. 2020 kl 15:29 skrev Adam Boyhan < [ mailto:adamb@xxxxxxxxxx | adamb@xxxxxxxxxx ] >: We are looking to role out a all flash Ceph cluster as storage for our cloud solution. The OSD's will be on slightly slower Micron 5300 PRO's, with WAL/DB on Micron 7300 MAX NVMe's. My main concern with Ceph being able to fit the bill is its snapshot abilities. For each RBD we would like the following snapshots 8x 30 minute snapshots (latest 4 hours) With our current solution (HPE Nimble) we simply pause all write IO on the 10 minute mark for roughly 2 seconds and then we take a snapshot of the entire Nimble volume. Each VM within the Nimble volume is sitting on a Linux Logical Volume so its easy for us to take one big snapshot and only get access to a specific clients data. Are there any options for automating managing/retention of snapshots within Ceph besides some bash scripts? Is there anyway to take snapshots of all RBD's within a pool at a given time? You could make a snapshot of the whole pool, that would cover all RBDs in it I gather?
