tunefs.reiserfs(8) progsreiserfs manual tunefs.reiserfs(8) 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 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 re- located 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 de- vice. 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 de- vice 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 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 REPORTING BUGS Report bugs to <torque@ukrpost.net> SEE ALSO mkfs.reiserfs(8), resizefs.reiserfs(8), cpfs.reiserfs(8) AUTHOR This manual page was written by Yury Umanets <torque@ukrpost.net> progsreiserfs 16 Apr, 2002 tunefs.reiserfs(8)
