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.
