What's the final feeling on snapshots ? * Luminous 12.2.10 on Debian stretch * ceph-fuse clients * 1 active MDS, some standbys * single FS, single namespace, no hardlinks * will probably create nested snapshots, ie. /1/.snaps/first and /1/2/3/.snaps/nested * will use the facility through VirtFS from within VMs, where ceph-fuse runs on the host server What's the risk of using that experimental feature (as said in [1]) ? * losing snapshots ? * losing the main/last contents ? * losing some directory trees, entire filesystem ? * other ?
