NAME

       fsck.ocfs2 - Check an OCFS2 file system.

SYNOPSIS

       fsck.ocfs2  [  -fFGnuvVy  ]  [  -b superblock block ] [ -B block size ]
       device

DESCRIPTION

       fsck.ocfs2 is used to check an OCFS2 file system.

       device is the file where the file system is  stored  (e.g.  /dev/sda1).
       It  will almost always be a device file but a regular file will work as
       well.

OPTIONS

       -b superblock block
              Normally, fsck.ocfs2 will read the  superblock  from  the  first
              block  of  the device.  This option specifies an alternate block
              that the superblock should be read from.

       -b blocksize
              The block size, specified in bytes, can range from 512 to  4096.
              A  value  of  0,  the  default,  is  used  to  indicate that the
              blocksize should be automatically detected.

       -f     Force checking even if the file system is clean.

       -F     Usually fsck.ocfs2 will check with cluster services and the  DLM
              to  make  sure that no one else in the cluster is actively using
              the device before proceeding.  -F skips this  check  and  should
              only  be  used  when  it  can be guaranteed that there can be no
              other users of the device while fsck.ocfs2 is running.

       -G     Usually fsck.ocfs2 will silently assume inodes whose  generation
              number  does  not match the generation number of the super block
              are unused inodes.  This option causes  fsck.ocfs2  to  ask  the
              user if these inodes should in fact be marked unused.

       -n     Give  the ’no’ answer to all questions that fsck will ask.  This
              guarantees that the file system will not  be  modified  and  the
              device  will be opened read-only.  The output of fsck.ocfs2 with
              this option can be redirected to produce  a  record  of  a  file
              system’s faults.

       -y     Give the ’yes’ answer to all questions that fsck will ask.  This
              will repair all faults that fsck.ocfs2 finds but will  not  give
              the operator a chance to intervene if fsck.ocfs2 decides that it
              wants to drastically repair the file system.

       -v     This option causes fsck.ocfs2 to produce a very large amount  of
              debugging output.

       -V     Print version information and exit.

EXIT CODE

       The  exit  code  returned  by  fsck.ocfs2  is  the sum of the following
       conditions:
            0    - No errors
            1    - File system errors corrected
            2    - File system errors corrected, system should
                   be rebooted
            4    - File system errors left uncorrected
            8    - Operational error
            16   - Usage or syntax error
            32   - E2fsck canceled by user request
            128  - Shared library error
