Hi Ceph'ers, I love the possibility to make snapshots on Cephfs systems. Although there is one thing that puzzles me. Creating snapshot takes no time to do and deleting snapshots can bring PGs into snaptrim state for some hours. While recovering data from a snapshot will always invoke a full data transfer, where data are "physically" being copied back into place. This can make recovering from snapshots on Cephfs a rather heavy procedure. I have even tried "mv" command but that also starts transfer real data instead of just moving metadata pointers. Am I missing some "ceph snapshot recover" command, that can move metadata pointers and make recovery much lighter, or is this just that way it is?
