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
