.SH DESCRIPTION
|
|
.B mkfs
|
|
creates a Linux MINIX file-system on a device (usually a disk partition).
|
|
|
|
The
|
|
.I device
|
|
is usually of the following form:
|
|
|
|
.nf
|
|
.RS
|
|
/dev/hda[1-8]
|
|
/dev/hdb[1-8]
|
|
/dev/sda[1-8]
|
|
/dev/sdb[1-8]
|
|
.RE
|
|
.fi
|
|
|
|
The
|
|
.I size-in-blocks
|
|
parameter is the desired size of the file system, in blocks. This
|
|
information can be determined from the
|
|
.BR fdisk (8)
|
|
program. Only block counts strictly greater than 10 and strictly less than
|
|
65536 are allowed.
|
|
.SH OPTIONS
|
|
.TP
|
|
.B \-c
|
|
Check the device for bad blocks before creating the file system. If any
|
|
are found, the count is printed.
|
|
.TP
|
|
.BI \-n " namelength"
|
|
Specify the maximum length of filenames. No space is allowed between the
|
|
.B \-n
|
|
and the
|
|
.IR namelength. Currently, the only allowable
|
|
values are 14 and 30.
|
|
.B 30 is the default.
|
|
.TP
|
|
.BI \-i " inodecount"
|
|
Specify the number of inodes for the filesystem.
|
|
.TP
|
|
.BI \-l " filename"
|
|
Read the bad blocks list from
|
|
.IR filename .
|
|
The file has one bad block number per line. The count of bad blocks read
|
|
is printed.
|
|
.SH "EXIT CODES"
|
|
The exit code returned by
|
|
.B mkfs.minix
|
|
is one of the following:
|
