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 |
       --journal-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 directories 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 format
	      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 separate 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 separate 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.

BUGS

       No other blocksizes but 4k are available.  Please, report about other bugs to the ReiserFS mail-list <reiserfs-list@namesys.com>
