Description
On shared systems like shared hosting it might be useful to prevent regular users from creating snapshots on CephFS.
A rogue user might create thousands of snapshots using a lot of space or even be a DoS for a MDS.
A min_uid/max_uid setting for the MDS or mount parameter for the kernel module might be useful to limit the creation of snapshots.
