NAME

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

SYNOPSIS

       ocfs2_hb_ctl -S -d <device>
       ocfs2_hb_ctl -K -d <device>
       ocfs2_hb_ctl -K -u <uuid>
       ocfs2_hb_ctl -I -d <device>
       ocfs2_hb_ctl -I -u <uuid>
       ocfs2_hb_ctl -h

DESCRIPTION

       ocfs2_hb_ctl is used to start  and  stop  the  heartbeat  on  an  OCFS2
       device.  One can either specify a device name or the device uuid. Users
       are strongly urged not to use this tool directly. mount.ocfs2 uses this
       tool  to  start  the heartbeat and the module uses it to stop it during
       umount.

OPTIONS

       -S     Starts the hearbeat  of  a  device.  The  device  name  must  be
              specified.

       -K     Stops  the  hearbeat  of  a  device.  One can specify either the
              device name or the device uuid.

       -I     Prints out the hearbeat reference counts for  the  region.  Once
              can specify either the device name or the device uuid.

       -d     Specify region by device name.

       -u     Specify region by device uuid.

       -h     Displays help and exit.

       uuid   mkfs.ocfs2 creates and populates the superblock with an uuid. To
              list the uuid of device sda1, do:

            # mounted.ocfs2 -d /dev/sda1
