[ –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, 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
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
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
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.
