mounted.ocfs2  is  used  to  detect OCFS2 volume(s) on a system. When run without specifying a device, it
       scans all the partitions listed in /proc/partitions.

       To view the list of OCFS2 volumes, do:

       # mounted.ocfs2 -d
       Device     Stack  Cluster     F  UUID                              Label
       /dev/sdc1  None                  23878C320CF3478095D1318CB5C99EED  localmount

       mounted.ocfs2 - Detects all OCFS2 volumes on a system.

       As this utility gathers information without taking any cluster locks, the information listed in the  full
       detect  mode  could  be stale. This is only problematic for volumes that were not cleanly umounted by the
       last node. Such volumes will show up mounted (as per this utility) on one or more nodes but are  in  fact
       not  mounted  on  any  node.  Such volumes are awaiting slot-recovery which is auto-performed on the next
       mount (or file system check).

-d     Lists the OCFS2 volumes along with their labels and  uuids.  It  also  lists  the  cluster  stack,
              cluster  name  and  the  cluster  flags. The possible cluster stacks are o2cb, pcmk and cman. None
              indicates a local mount or a non-clustered volume. A G cluster flag indicates global-heartbeat for
              the o2cb cluster stack.

       -f     Lists the OCFS2 volumes along with the list of nodes that have mounted the volume.
