RBD lock on unmount

    Hi
    I've set up a Ceph Cluster with and RBD storage device for use in
      a pacemaker/corosync cluster. When attempting to move the
      resources from one node to the other, the filesystem on the RBD
      will not unmount. lsof and fuser show no files in use on the
      device. I thought this may be an issue with an NFS lock, so I
      moved the ceph OSD and monitor off the machine where the
      filesystem is mounted to a virtual machine, however I'm still
      unable to unmount the filesystem.
    Is this a known issue with RBD filesystem mounts? Is there a
      system change I need to make in order to get the filesystem to
      reliably unmount?
    Thanks in advance,
    --
