MKREISERFS(8)

NAME
mkreiserfs - create a Linux ReiserFS file system

SYNOPSIS
mkreiserfs [ -dfV ] [ -b | --block-size N ] [ -h | --hash HASH ] [ -u | --uuid UUID ] [ -l | --label LABEL ] [ --format FORMAT ] [ -q | --quiet ] [ -j | --journal-device FILE ] [ -s | --journal-size N ] [ -o | --journal-offset N ] [ -t | --transaction-max-size N ] device [ filesystem-size ]

DESCRIPTION
It creates a Linux ReiserFS file system on a device (usually a disk partition).

device
    is the special file corresponding to the device (e.g /dev/hdXX for IDE disk partition or /dev/sdXX for SCSI disk partition).

filesystem-size
    size of filesystem in blocks. If omitted, it will be determined by mkreiserfs automatically.

OPTIONS

-b | --block-size N
    N is block size in bytes. 4096 only for now.

-h | --hash HASH
    HASH specifies the name of hash function file names in directories will be sorted with. Choose one of r5, rupasov, tea. r5 is default

--format FORMAT
    FORMAT specifies a format new filsystem has to be of. Choose one of 3.5 and 3.6. If none is specified mkreiserfs will create format 3.6 if running kernel is 2.4, 3.5 if 2.2 is running, and will refuse creation under other kernels.

-u | --uuid UUID
    Set the universally unique identifier ( UUID ) of the filesystem to UUID (see also uuidgen(8)). The format of the UUID is a series of hex digits separated by hypthens, like this: "c1b9d5a2-f162-11cf-9ece-0020afc76f16". If the option skipped, mkreiserfs generates a new one.

-l | --label LABEL
    Set the volume label of the filesystem. LABEL can be at most 16 characters long; if it is longer than 16 characters, mkreiserfs will truncate it.

-q | --quiet
    Make mkreiserfs to work quiet without producing any message, progress and question. It is useful if you run mkreiserfs in a script. For use by end users only.

-j | --journal-device FILE
    FILE is name of block device where the file system is to have journal on.

-o | --journal-offset N
    N is an offset where journal starts when it is to be on a separate device. Default is 0. Makes no effect when journal is to be on a host device

-s | --journal-size N
    N is size of journal in blocks. When journal is to be on a separate device - its size defaults to number of blocks that device has. When journal is to be on a host device - its size defaults 8193 and maximal possible value is 32749 (for blocksize 4k). Minimun is 513 for both cases.

-t | --transaction-max-size N
    N is the maximum transaction size parameter for the journal. The default, and max possible, value is 1024 blocks. It should be less than half the size of the journal. If specifed incorrectly, it will be adjusted.

-f  This forces mkreiserfs to continue even if device is either whole disk, or looks mounted or is not a block device. Specified more than once allows to avoid asking for confirmation.

-d  This makes mkreiserfs to print debugging information during mkreiserfs.

-V  This prints version and exits.
