A way to delete all CephFS snapshots in a given directory

deleteAllCephFsSnapshots.sh

#!/bin/bash
#$1 = CephFS directory

# Snapshots starting with underscore names are related to snapshots based in a higher directory and can't be used.
# Therefore they are filterd out with `grep`

find $1 -type d | while read i; do
  ls --color=none $i/.snap | while read j; do
    echo $i/.snap/$j
  done
done | grep --color=never ".snap/[^_]" | xargs rmdir
