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 ] [ -j | --jour-
       nal-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 directo-
              ries 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 for-
              mat  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.

       -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 sepa-
              rate 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 sepa-
              rate 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.
