mkfs.minix

MKFS.MINIX(8)						       System Administration						     MKFS.MINIX(8)

NAME

       mkfs.minix - make a Minix filesystem

SYNOPSIS

       mkfs.minix [-c|-l filename] [-n namelength] [-i inodecount] [-v] device [size-in-blocks]

DESCRIPTION

       mkfs.minix creates a Linux MINIX filesystem on a device (usually a disk partition).

       The device is usually of the following form:

	      /dev/hda[1-8] (IDE disk 1)
	      /dev/hdb[1-8] (IDE disk 2)
	      /dev/sda[1-8] (SCSI disk 1)
	      /dev/sdb[1-8] (SCSI disk 2)

       The  size-in-blocks parameter is the desired size of the file system, in blocks.  It is present only for backwards compatibility.  If omit-
       ted the size will be determined automatically.  Only block counts strictly greater than 10 and strictly less than 65536 are allowed.

OPTIONS

       -c     Check the device for bad blocks before creating the filesystem.  If any are found, the count is printed.

       -n namelength
	      Specify the maximum length of filenames.	Currently, the only allowable values are 14 and 30.  The default is 30.  Note that kernels
	      older than 0.99p7 only accept namelength 14.

       -i inodecount
	      Specify the number of inodes for the filesystem.

       -l filename
	      Read the list of bad blocks from filename.  The file has one bad-block number per line.  The count of bad blocks read is printed.

       -1     Make a Minix version 1 filesystem.

       -2, -v Make a Minix version 2 filesystem.

       -3     Make a Minix version 3 filesystem.

EXIT CODES

       The exit code returned by mkfs.minix is one of the following:

       0      No errors

       8      Operational error

       16     Usage or syntax error

SEE ALSO

       mkfs(8), fsck(8), reboot(8)

AVAILABILITY

       The mkfs.minix command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
