mkfs.minix - make a Linux MINIX filesystem


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


mkfs.minix creates a Linux MINIX file-system 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 omitted the size will be determined automatically. Only block counts strictly greater than 10 and strictly less than 65536 are allowed.


-c Check the device for bad blocks before creating the file system. 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 bad blocks list from filename. The file has one bad block number per line. The count of bad blocks read is printed.
-v Make a Minix version 2 filesystem.
