SYNOPSIStunefs.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
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
