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.
- -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, 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 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.
