reiserfsck - check a Linux Reiserfs file system


SYNOPSIS

       reiserfsck  [  -arvixoV  ] [ -l logfilename ] [ --rebuild-
       tree ] [ --check ] [ --rebuild-sb ] [ --interactive ] [
        --logfile  logfilename ] [ --fix-fixable ] device


DESCRIPTION

       It looks for reiserfs  filesystem  on  a  device,  replays
       transactions  which are to be replayed and either check or
       repair the filesystem

       device is the special file  corresponding  to  the  device
              (e.g  /dev/hdXX for IDE disk partition or /dev/sdXX
              for SCSI disk partition).


OPTIONS

       --check
              This  checks  filesystem  consistency.  This  is  a
              default  action.  It  may  be  used on a filesystem
              mounted read-only

       --rebuild-tree
              This rebuilds  filesystem  tree  using  leaf  nodes
              found  on  the  device.  Normally,  you do not need
              this, but if you have  to  rebuild  tree  -  please
              backup  whole  partition first or at least the most
              important data if you can mount the partition.

       --rebuild-sb

       --interactive, -i
              This makes reiserfsck to stop after each pass  com­
              pleted.

       --quiet, -q
              have reiserfsck to not reflect its progress

       --nolog, -n
              have reiserfsck to not log anything

       --logfile filename, -l  filename
              have reiserfsck to put info about found corruptions
              in logfile rather than on stderr

       --fix-fixable, -x
              have reiserfsck to recover corruptions which can be
              fixed w/o --rebuild-tree when it is runnig in check
              mode. Corruptions which can be fixed  so  far:  bad
              pointers  to data blocks, wrong directory's st_size
              and  st_blocks,  directories  entries  pointing  to
              nowhere can be deleted

              have  reiserfsck  to  fix: file sizes when they are
              bigger than real file size, set file mode to  regu­
              lar  file  when  mode  looks  wrong  and  to try to
              recover "objectid sharing" problem

       -a     When it is set -  reiserfsck  assumes  that  it  is
              called by fsck -A and just returns even if filesys­
              tem seems not umounted cleanly

       -r     ignored

       -V     Prints version and exits
