NAME

       debugfs.ocfs2 - OCFS2 file system debugger.

SYNOPSIS

       debugfs.ocfs2 [-f cmdfile] [-V] [-w] [-?] [device]

DESCRIPTION

       The  debugfs.ocfs2  is  an  interactive file system debugger. It can be
       used to examine the state of an OCFS2 filesystem. device is the special
       file  corresponding  the  device  containing  the OCFS2 filesystem (e.g
       /dev/hdxx).

OPTIONS

       -f, --file cmdfile
              Causes debugfs.ocfs2  to  read  in  commands  from  cmdfile  and
              execute them. It exits after all the commands are executed.

       -w, --write
              Specifies  that  the  filesystem  should be opened in read-write
              mode.  Without this option, the  filesystem  is  opened  in  the
              read-only mode.

       -V, --version
              Print version information and exit.

       -?, --help
              Displays help and exit.

SPECIFYING FILES

       Many  debugfs.ocfs2  commands take a filespec as an argument to specify
       an inode (as  opposed  to  a  pathname)  in  the  filesystem  which  is
       currently  opened  by  debugfs.ocfs2.  The  filespec  argument  may  be
       specified in two forms. The first form is an inode number surrounded by
       angle  brackets,  e.g.,  <32>.  The  second  form is a pathname; if the
       pathname is prefixed by a forward slash (’/’), then it  is  interpreted
       relative  to  the  root  of the filesystem which is currently opened by
       debugfs.ocfs2. If not, the path is interpreted relative to the  current
       working directory as maintained by debugfs.ocfs2, which can be modified
       using the command cd. If the pathname is prefixed by a  double  forward
       slash (’//’), then it is interpreted relative to the root of the system
       directory of the filesystem opened by debugfs.ocfs2.

COMMANDS

       This is a list of the commands which debugfs.ocfs2 supports.

       cat filespec
              Dump the contents of inode filespec to stdout.

       cd filespec
              Change the current working directory to filespec.

       chroot filespec
              Change the root directory to be the directory filespec.

       close  Close the currently opened filesystem.

       curdev Show the currently open device.

       dump [-p] filespec outfile
              Dump the contents of the  inode  filespec  to  the  output  file
              outfile.  If  the  -p is given, set the owner, group, timestamps
              and  permissions  information  on  outfile  to  match  those  of
              filespec.

       extent block#
              Display the contents of the extent structure at block#.

       group block#
              Display the contents of the group structure at block#.

       help, ?
              Print the list of commands understood by debugfs.ocfs2.

       lcd directory
              Change  the  current  working  directory  of  the  debugfs.ocfs2
              process to the directory on the native filesystem.

       logdump node#
              Display the contents of the journal for node node#.

       ls [-l] filespec
              Print the listing  of the files in the directory  filespec.  The
              -l flag will list files in the long format.

       open device
              Open the filesystem on device.

       quit, q
              Quit debugfs.ocfs2.

       rdump [-v] filespec outdir
              Recursively   dump  directory  filespec  and  all  its  contents
              (including regular files, symbolic links and other  directories)
              into  the  outdir  which  should be an existing directory on the
              native filesystem.

       slotmap
              Display the contents of the slotmap system file.

       stat filespec
              Display the  contents  of  the  inode  structure  of  the  inode
              filespec.

       stats  Display the contents of the super block.

ACKNOWLEDGEMENT

       This tool has been modelled after debugfs, a debugging tool for ext2.
