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.  This tool assumes that the nodes detected on the system are part of the same
       cluster as the one specified in /etc/ocfs2/cluster.conf.

OPTIONS

       -d     Lists the OCFS2 volumes along with their labels and uuids.  If a device is not specified, it scans all the devices  in  /proc/parti-
	      tions.

       -f     Lists  the OCFS2 volumes along with the list of nodes that have mounted the volume. The node names are listed if the O2CB cluster is
	      online. Note: As this information is gathered using dirty-read, the information may be stale.

EXAMPLES

       [root@node1 ~]# mounted.ocfs2 -d
       Device	   FS	  Stack  UUID				   Label
       /dev/sdb1   ocfs2  local  2D1C9636FE38462DB43A75D1DA592207  vmvol
       /dev/sdj1   ocfs2  o2cb	 FF2E239B02D941FEAF25BDAE8DD553B9  dbstore

       [root@node1 ~]# mounted.ocfs2 -f
       Device	   FS	  Nodes
       /dev/sdb1   ocfs2  node15, node1

NAME

       ocfs2_hb_ctl - Starts and stops the OCFS2 heartbeat on a given device.

SYNOPSIS

       ocfs2_hb_ctl -S -d device service
       ocfs2_hb_ctl -S -u uuid service
       ocfs2_hb_ctl -K -d device service
       ocfs2_hb_ctl -K -u uuid service
       ocfs2_hb_ctl -I -d device
       ocfs2_hb_ctl -I -u uuid
       ocfs2_hb_ctl -P -d device [-n io_priority]
       ocfs2_hb_ctl -P -u uuid [-n io_priority]
       ocfs2_hb_ctl -h

DESCRIPTION

       ocfs2_hb_ctl starts and stops the heartbeat on a OCFS2 device.  Users are strongly urged not to use this tool directly. It is automatically
       invoked by mount.ocfs2 and other tools that require heartbeat notifications.

       The tools accepts devices to be specified by its name or its uuid. Service denotes the application that is requesting the heartbeat notifi-
       cation.

OPTIONS

       -S     Starts the heartbeat.

       -K     Stops the heartbeat.

       -I     Prints the heartbeat reference counts for that heartbeat region.

       -d     Specify region by device name.

       -u     Specify region by device uuid.

       -n     Adjust  IO  priority  for  the  heartbeat  thread. This option calls the ionice tool to set its IO scheduling class to realtime with
	      scheduling class data as provided.  This option is usable only with the O2CB cluster stack.

       -h     Displays help and exit.
