Unfortunately, there’s not any such ability. We are starting long-term work on making this smoother, but CephFS snapshots are read-only and there’s no good way to do a constant-time or low-time “clone” operation, so you just have to copy the data somewhere and start work on it from that position :/ That’s what the subvolume clone interface does.

*Ceph-version*: Quincy *OS*: Centos 8 stream

*Issue*: Not able to find a standardized restoration procedure for subvolume snapshots.

*Description:* Hi team,

We are currently working in a 3-node ceph cluster. We are currently exploring the scheduled snapshot capability of the ceph-mgr module. To enable/configure scheduled snapshots, we followed the following link:

https://docs.ceph.com/en/quincy/cephfs/snap-schedule/

The scheduled snapshots are working as expected. But we are unable to find any standardized restoration procedure for the same.

We have found the following link( not official documentation): https://www.suse.com/support/kb/doc/?id=000019627

We have also found a link of cloning a new subvolume from snapshots: https://docs.ceph.com/en/reef/cephfs/fs-volumes/ (Section: Cloning Snapshots)

Is there a standard procedure to restore from a snapshot. By this I mean, is there some kind of command link maybe ceph fs subvolume snapshot restore <snapshot-name>

Or any other procedure please let us know.

Thanks and Regards, Kushagra Gupta
