NAME
gfs2_fsck - Offline GFS2 file system checkerSYNOPSIS
gfs2_fsck [OPTION]... DEVICEWARNING
All GFS2 nodes must have the GFS2 filesystem unmounted before running gfs2_fsck. Failure to unmount all nodes may result in filesystem corruption.DESCRIPTION
gfs2_fsck will check that the GFS2 file system on a device is structurally valid. It should not be run on a mounted file system. If file system corruption is detected, it will attempt to repair the file system. There is a limit to what gfs2_fsck can do. If important file system structures are destroyed, such that the checker cannot determine what the repairs should be, reparations could fail.GFS2 is a journaled file system, and as such should be able to repair damages to the file system on its own. However, faulty hardware has the ability to write incomplete blocks to a file system thereby causing corruption that GFS2 cannot fix. The first step to ensuring a healthy file system is the selection of reliable hardware (i.e. storage systems that will write complete blocks - even in the event of power failure).
