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.
