OCFS2 uses the debugfs file system to allow
access from user space to information about its in-kernel state.
You must mount the debugfs file system to be
able to use the debugfs.ocfs2 command.
To mount the debugfs file system, add the
following line to /etc/fstab:
debugfs /sys/kernel/debug debugfs defaults 0 0
and run the mount -a command.
