SYNOPSIS

       tunefs.reiserfs options device

DESCRIPTION

       resizefs.reiserfs  is  a reiserfs filesystem tuning program. It changes
       journal parameters, journal device, label and uuid.

OPTIONS

       -v, --version
              displays current version

       -u, --usage
              displays program usage

       -j FILE, --journal-device=FILE
              device where journal is lies. Needed to perform journal  replay-
              ing  (when  journal params will be changed) to make sure that no
              non-replayed transactions found.

       -d FILE, --journal-new-device=FILE
              new journal device. If you are trying  to  change  journal  from
              relocated device to the host device (new journal device the same
              as host device), then program  will  be  looking  for  available
              space  on  host device. If free space on the host device enought
              to put journal on them,  journal  will  be  switched  onto  host
              device. If the area for journal on the host occupied by reiserfs
              tree (this possible if filesystem was created  with  journal  on
              separated device), relocation of data blocks from this area onto
              free blocks will be performed.

       -s N, --journal-size=N
              journal size. This is the journal  size.  For  journal  on  host
              device  it must be gretter than 512 blocks and lesser than count
              of blocks described by first bitmap block. In other words, jour-
              nal  must be lesser or equals block_size * 8 journal offset - 1.
              In the case given journal size not equals previous journal  size
              tunefs.reiserfs  will  perform  journal  resizing. For relocated
              journal it will be recreated with new params.  And for  standard
              journal  data  blocks will be relocated first, then journal will
              be recreated with new boundaries.

              And for journal on separated device journal size may be  as  big
              as device length - journal offset - 1.

       -o N, --journal-offset=N
              journal  offset for relocated journal. You can't to change jour-
              nal offset for standard journal.

       -t N, --transaction-max-size=N
              transaction max size

       -n, --no-journal-available
