Hello, Is there a way to find out all the clients where the volumes are mapped from a central point? We have a large fleet of machines that use ceph rbd volumes. For some maintenance purposes, we need to find out if a volume is mapped anywhere before acting on it. Right now we go and query each client machines with `rbd showmapped` commands. Is there a variant of this CLI that lists all mappings on a single node (ceph mon for instance)? Thanks, Shridhar
