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
