7.3.2 Mounting the debugfs File System

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.
