MKREISERFS(8)                        System Manager's Manual                        MKREISERFS(8)



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 sepa‐
              rated  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  jour‐
              nal.

       -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 jour‐
              nal 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 jour‐
              nal 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 jour‐
              nal. 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.
