NAME

       tunefs.reiserfs - a reiserfs filesystem tuning program.


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
              replaying (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,
              journal 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
              journal offset for standard journal.

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

       -n, --no-journal-available
              no journal available now. This options lets program know, that
              no journal available by now. Therefore no journal replaying will
              be performed.

       -l LABEL, --label=LABEL
              sets volume label

       -i UUID, --uuid=UUID
              sets given uuid to superblock

       -q, --quiet
              non-interactive mode
