.TP
.I 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).
.TP
.I filesystem-size
is the size in blocks of the filesystem. If omitted, \fBmkfs.reiserfs\fR will
automatically set it.
.SH OPTIONS
.TP
\fB-b\fR | \fB--block-size \fIN\fR
\fIN\fR is block size in bytes. It may only be set to a power of 2 within the
512-8192 interval.
.TP
\fB-h\fR | \fB--hash \fIHASH\fR
\fIHASH\fR specifies which hash function will sort the names in the directories.
Choose from r5, rupasov, or tea. r5 is the default one.
.TP
\fB--format \fIFORMAT\fR
\fIFORMAT\fR specifies the format for the new filsystem. Choose format 3.5 or
3.6. If none is specified \fBmkfs.reiserfs\fR 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.
.TP
\fB-u\fR | \fB--uuid \fIUUID\fR
Sets the Universally Unique IDentifier of the filesystem to \fIUUID\fR
(see also \fBuuidgen(8)\fR). The format of the \fIUUID\fR is a series
of hex digits separated by hypthens, e.g.: "c1b9d5a2-f162-11cf-9ece-0020afc76f16".
If the option is skipped, \fBmkfs.reiserfs\fR will by default generate a new
\fIUUID\fR.
.TP
\fB-l\fR | \fB--label \fILABEL\fR
Sets the volume label of the filesystem. \fILABEL\fR can at most be 16
characters long; if it is longer than 16 characters, \fBmkfs.reiserfs\fR will
truncate it.
.TP
\fB-q\fR | \fB--quiet \fR
Sets \fBmkfs.reiserfs\fR to work quietly without producing messages, progress or
questions. It is useful, but only for use by end users, if you run \fBmkfs.reiserfs\fR
in a script.
.TP
\fB-j\fR | \fB--journal-device \fIFILE\fR
\fIFILE\fR is the name of the block device on which is to be places the
filesystem journal.
.TP
\fB-o\fR | \fB--journal-offset \fIN\fR
\fIN\fR is the offset where the journal starts when it is to be on a separate
device. Default is 0. \fIN\fR has no effect when the journal is to be on the
host device.
.TP
\fB-s\fR | \fB--journal-size \fIN
\fIN\fR 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).
.TP
\fB-t\fR | \fB--transaction-max-size \fIN
\fIN\fR 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.
.TP
\fB-B\fR | \fB--badblocks \fIfile
\fIFile\fR 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
\fB/sbin/badblocks -b block-size device\fR.
.TP
\fB-f\fR
Forces \fBmkfs.reiserfs\fR to continue even when the device is the whole disk,
looks mounted, or is not a block device. If \fB-f\fR is specified more than
once, it allows the user to avoid asking for confirmation.
.TP
\fB-d\fR
Sets \fBmkfs.reiserfs\fR to print debugging information during \fBmkfs.reiserfs\fR.
.TP
\fB-V\fR
Prints the version and then exits.

/* mkreiserfs is very simple. It skips first 64k of device, and then
writes the super block, the needed amount of bitmap blocks (this
amount is calculated based on file system size), and root block.
Bitmap policy is primitive: it assumes, that device does not have
unreadable blocks, and it occupies first blocks for super, bitmap
and root blocks. bitmap blocks are interleaved across the disk,
mainly to make resizing faster. */
