NAME         top

       mkfs.minix - make a Minix filesystem

SYNOPSIS         top

       mkfs.minix [options] device [size-in-blocks]

DESCRIPTION         top

       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 device may be a block device or an image file of one, but
       this is not enforced.  Expect not much fun on a character device

       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.

OPTIONS         top

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

       -n, --namelength length
              Specify the maximum length of filenames.  Currently, the
              only allowable values are 14 and 30 for file system
              versions 1 and 2.  Version 3 allows only value 60.  The
              default is 30.

              Use exclusive BSD lock for device or file it operates.
              The optional argument mode can be yes, no (or 1 and 0) or
              nonblock.  If the mode argument is omitted, it defaults to
              "yes".  This option overwrites environment variable
              $LOCK_BLOCK_DEVICE.  The default is not to use any lock at
              all, but it's recommended to avoid collisions with udevd
              or other tools.

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

       -l, --badblocks 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.  This is the default.

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

       -3     Make a Minix version 3 filesystem.

       -V, --version
              Display version information and exit.  The long option
              cannot be combined with other options.

       -h, --help
              Display help text and exit.

ENVIRONMENT         top

              use exclusive BSD lock.  The mode is "1" or "0".  See
              --lock for more details.

EXIT STATUS         top

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

       0      No errors

       8      Operational error
