NAME
       mkreiserfs - The create tool for the Linux ReiserFS filesystem.

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 ] [  -B  |  --bad-
       blocks file ]  device [ filesystem-size ]

DESCRIPTION
       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).

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

OPTIONS
       -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
              one.

       --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 ker-
              nels.

       -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  incor-
              rectly, 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  speci-
              fied more than once, it allows the user to avoid asking for con-
              firmation.

       -d     Sets mkreiserfs to print debugging  information  during  mkreis-
              erfs.

       -V     Prints the version and then exits.
