MKFS(8)								       MKFS(8)

NAME
       mkfs - construct a file system

SYNOPSIS
       /usr/etc/mkfs [ -N ] special size [ nsect [ ntrack [ blksize [ fragsize
       [ ncpg [ minfree [ rps [ nbpi [ opt ] ] ] ] ] ] ] ] ]

DESCRIPTION
       N.B.: file system are normally created with the newfs(8) command.

       Mkfs constructs a file system by writing on the	special	 file  special
       unless  the -N flag has been specified.	The numeric size specifies the
       number of sectors in the file system.  Mkfs builds a file system with a
       root directory and a lost+found directory.  (see fsck(8)) The number of
       i-nodes is calculated as a function of the file system size.   No  boot
       program is initialized by mkfs (see newfs(8).)

       The  optional  arguments allow fine tune control over the parameters of
       the file system.	 Nsect specify the number of sectors per track on  the
       disk.   Ntrack  specify	the number of tracks per cylinder on the disk.
       Blksize gives the primary block size for files on the file system.   It
       must be a power of two, currently selected from 4096 or 8192.  Fragsize
       gives the fragment size for files on the	 file  system.	 The  fragsize
       represents  the smallest amount of disk space that will be allocated to
       a file.	It must be a power of two currently selected  from  the	 range
       512  to 8192.  Ncpg specifies the number of disk cylinders per cylinder
       group.  This number must be in the range 1 to  32.   Minfree  specifies
       the  minimum  percentage	 of  free  disk	 space allowed.	 Once the file
       system capacity reaches this threshold, only the super-user is  allowed
       to allocate disk blocks.	 The default value is 10%.  If a disk does not
       revolve at  60  revolutions  per	 second,  the  rps  parameter  may  be
       specified.   If	a  file system will have more or less than the average
       number of files the nbpi (number of bytes per inode) can	 be  specified
       to  increase  or decrease the number of inodes that are created.	 Space
       or time optimization preference can be specified	 with  opt  values  of
       ``s''  for  space  or  ``t''  for time.	Users with special demands for
       their file systems  are	referred  to  the  paper  cited	 below	for  a
       discussion of the tradeoffs in using different configurations.

BUGS
       There should be some way to specify bad blocks.
