12. Repairing a File System

When nodes fail with the file system mounted, file-system journaling allows fast recovery.
However, if a storage device loses power or is physically disconnected, file-system corruption
may occur. (Journaling cannot be used to recover from storage subsystem failures.) When that
type of corruption occurs, you can recover the GFS file system by using the
command.
The command must only be run on a file system that is unmounted from all nodes.
