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  |
       --badblocks 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 kernels.

       -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,  mkreis-
	      erfs  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, mkreis-
	      erfs 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 confirmation.

       -d     Sets mkreiserfs to print debugging information during mkreiserfs.

       -V     Prints the version and then exits.
