.SH DESCRIPTION
|
|
It creates a Linux ReiserFS file system on a device
|
|
(usually a disk partition).
|
|
.TP
|
|
.I device
|
|
is the special file corresponding to the device (e.g /dev/hdXX for
|
|
IDE disk partition or /dev/sdXX for SCSI disk partition).
|
|
.TP
|
|
.I filesystem-size
|
|
size of filesystem in blocks. If omitted, it will be
|
|
determined by
|
|
.B mkreiserfs
|
|
automatically.
|
|
.SH OPTIONS
|
|
.TP
|
|
\fB-b\fR | \fB--block-size \fIN\fR
|
|
\fIN\fR is block size in bytes. 4096 only for now.
|
|
.TP
|
|
\fB-h\fR | \fB--hash \fIHASH\fR
|
|
\fIHASH\fR specifies the name of hash function file names in directories
|
|
will be sorted with. Choose one of r5, rupasov, tea. r5 is default
|
|
.TP
|
|
\fB--format \fIFORMAT\fR
|
|
\fIFORMAT\fR specifies a format new filsystem has to be of. Choose one
|
|
of 3.5 and 3.6. If none is specified mkreiserfs will create format 3.6
|
|
if running kernel is 2.4, 3.5 if 2.2 is running, and will refuse
|
|
creation under other kernels.
|
|
.TP
|
|
\fB-u\fR | \fB--uuid \fIUUID\fR
|
|
Set the universally unique identifier (\fB UUID \fR) of the filesystem to
|
|
\fIUUID\fR (see also \fBuuidgen(8)\fR). The format of the UUID is a
|
|
series of hex digits separated by hypthens, like this:
|
|
"c1b9d5a2-f162-11cf-9ece-0020afc76f16". If the option skipped,
|
|
mkreiserfs generates a new one.
|
|
.TP
|
|
\fB-l\fR | \fB--label \fILABEL\fR
|
|
Set the volume label of the filesystem. \fILABEL\fR can be at most 16
|
|
characters long; if it is longer than 16 characters, mkreiserfs will truncate it.
|
|
.TP
|
|
\fB-j\fR | \fB--journal-device \fIFILE\fR
|
|
\fIFILE\fR is name of block device where the file system is to have
|
|
journal on.
|
|
.TP
|
|
\fB-o\fR | \fB--journal-offset \fIN\fR
|
|
\fIN\fR is an offset where journal starts when it is to be on a
|
|
separate device. Default is 0. Makes no effect when journal is to be
|
|
on a host device
|
|
.TP
|
|
\fB-s\fR | \fB--journal-size \fIN
|
|
\fIN\fR is size of journal in blocks. When journal is to be on a
|
|
separate device - its size defaults to number of blocks that device
|
|
has. When journal is to be on a host device - its size defaults 8193
|
|
and maximal possible value is 32749 (for blocksize 4k). Minimun is 513
|
|
for both cases.
|
|
.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 specifed incorrectly, it will be
|
|
adjusted.
|
|
.TP
|
|
\fB-f\fR
|
|
This forces mkreiserfs to continue even if device is either whole
|
|
disk, or looks mounted or is not a block device. Specified more than
|
|
once allows to avoid asking for confirmation.
|
|
.TP
|
|
\fB-d\fR
|
|
This makes mkreiserfs to print debugging information during mkreiserfs.
|
|
.TP
|
|
\fB-V\fR
|
|
This prints version and exits.
