Hey, We make use of the ctdb_mutex_ceph_rados_helper so the lock file just gets stored within CephFS metadata pool rather than on a shared CephFS mount as a file. We don't recommend storing directly on CephFS as if the mount hosting the lock file is to go down we have seen the mds mark as stale, and then another client can't reach the lockfile causing problems with CTDB. I believe the source Angelo is referring to is within a video we did about cephfs+samba a couple years ago, Brett does a much better job of explaining it than me hahahaha: https://www.youtube.com/watch?v=Gel9elLSEsQ It's at 2:44 Regards, Bailey > -----Original Message----- > From: Alexander E.
