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.
