       mkreiserfs creates a Linux ReiserFS filesystem on a device (usually a
       disk partition).

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

              is the size in blocks of the filesystem. If omitted, mkreiserfs
              will automatically set it.

       -b | --block-size N
              N is block size in bytes. It may only be set to a power of 2
              within the 512-8192 interval.

       -h | --hash HASH
              HASH specifies which hash function will sort the names in the
              directories.  Choose from r5, rupasov, or tea. r5 is the default

       --format FORMAT
              FORMAT specifies the format for the new filsystem. Choose format
              3.5 or 3.6. If none is specified mkreiserfs will create format
              3.6 if running kernel is 2.4 or higher, and format 3.5 if kernel
              2.2 is running, and will refuse creation under all other

       -u | --uuid UUID
              Sets  the  Universally  Unique  IDentifier  of  the  filesystem
              to  UUID (see  also  uuidgen(8)).  The  format  of  the  UUID
              is  a  series of  hex  digits separated by hypthens, e.g.:
              "c1b9d5a2-f162-11cf-9ece-0020afc76f16".  If  the option  is
              skipped,  mkreiserfs  will by default generate a new UUID.

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

       -q | --quiet
              Sets mkreiserfs to work quietly without producing messages,
              progress or questions. It is useful, but only for use by end
              users, if you run mkreiserfs in a script.

       -j | --journal-device FILE
              FILE is the name of the block device on which is to be places
              the filesystem journal.

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

       -s | --journal-size N
              N is the size of the journal in blocks. When the journal is to
              be on a separate device, its size defaults to the number of
              blocks that the device has.  When journal is to be on the host
              device, its size defaults to 8193 and the maximal possible size
              is 32749 (for blocksize 4k). The minimum size is 513 blocks
              (whether the journal is on the host or on a separate device).

       -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 specified
              incorrectly, it will automatically be adjusted.

       -B | --badblocks file
              File is the file name of the file that contains the list of
              blocks to be marked as bad on the filesystem. This list can be
              created by /sbin/badblocks -b block-size device.

       -f     Forces mkreiserfs to continue even when the device is the whole
              disk, looks mounted, or is not a block device. If -f is
              specified more than once, it allows the user to avoid asking for

       -d     Sets mkreiserfs to print debugging information during

       -V     Prints the version and then exits.
