mounted.ocfs2(8)	      OCFS2 Manual Pages	      mounted.ocfs2(8)

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

SYNOPSIS
       mounted.ocfs2 [-d] [-f] [device]

DESCRIPTION
       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.

OPTIONS
       -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.

NOTES
       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).

EXAMPLES
       To view the list of OCFS2 volumes, do:

       # mounted.ocfs2 -d
       Device	  Stack	 Cluster     F	UUID				  Label
       /dev/sdc1  None			23878C320CF3478095D1318CB5C99EED  localmount
       /dev/sdd1  o2cb	 webcluster  G	8AB016CD59FC4327A2CDAB69F08518E3  webvol
       /dev/sdg1  o2cb	 webcluster  G	77D95EF51C0149D2823674FCC162CF8B  logsvol
       /dev/sdh1  o2cb	 webcluster  G	BBA1DBD0F73F449384CE75197D9B7098  scratch
       /dev/sdk1  o2cb	 webcluster  G	DCDA2845177F4D59A0F2DCD8DE507CC3  hb1

       To view the list of nodes that have potentially (see notes) mounted the
       OCFS2 volumes, do:

       # mounted.ocfs2 -f
       Device	  Stack	 Cluster     F	Nodes
       /dev/sdc1  None
       /dev/sdd1  o2cb	 webcluster  G	node1, node3, node10
       /dev/sdg1  o2cb	 webcluster  G	node1, node3, node10
       /dev/sdh1  o2cb	 webcluster  G	Not mounted
       /dev/sdk1  o2cb	 webcluster  G	node1, node3, node10
