NAME

6       mounted.ocfs2 - Detects all OCFS2 volumes on a system.
7

SYNOPSIS

9       mounted.ocfs2 [-d] [-f] [device]
10

DESCRIPTION

12       mounted.ocfs2  is  used to detect OCFS2 volume(s) on a system. When run
13       without specifying a device, it scans  all  the  partitions  listed  in
14       /proc/partitions.
15
16

OPTIONS

18       -d     Lists  the  OCFS2  volumes along with their labels and uuids. It
19              also lists the cluster  stack,  cluster  name  and  the  cluster
20              flags. The possible cluster stacks are o2cb, pcmk and cman. None
21              indicates a local mount or a non-clustered volume. A  G  cluster
22              flag indicates global-heartbeat for the o2cb cluster stack.
23
24
25       -f     Lists  the  OCFS2 volumes along with the list of nodes that have
26              mounted the volume.

NOTES

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

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

55       /dev/sdc1  None
