mkfs(1M)		System Administration Commands		      mkfs(1M)

NAME
       mkfs - construct a file system

SYNOPSIS
       mkfs    [-F FSType]    [generic_options]	  [-o FSType-specific_options]
       raw_device_file [operands]

DESCRIPTION
       The mkfs utility constructs a file system  on  the  raw_device_file  by
       calling the specific mkfs module indicated by  -F FSType.

       Note: ufs file systems are normally created with the newfs(1M) command.

       generic_options	are  independent  of  file  system  type.  FSType-spe‐
       cific_options is a comma-separated  list of  keyword=value pairs	 (with
       no  intervening	spaces),  which	 are  FSType-specific. raw_device_file
       specifies the disk partition on which to write the file system.	It  is
       required	  and	 must  be  the	first  argument	 following  the	  spe‐
       cific_options (if any). operands are  FSType-specific. See the  FSType-
       specific	 manual	 page  of   mkfs  (for	example,  mkfs_ufs (1M)) for a
       detailed description.

OPTIONS
       The following are the generic options for mkfs:

       -F	Specify the  FSType to be constructed. If  -F  is  not	speci‐
		fied,  the  FSType is determined from  /etc/vfstab by matching
		the  raw_device_file with a  vfstab entry,  or	by  consulting
		the  /etc/default/fs file.

       -V	Echo  the  complete  command line, but do not execute the com‐
		mand. The command line is generated by using the  options  and
		arguments provided and adding to them information derived from
		/etc/vfstab or	/etc/default/fs. This option may  be  used  to
		verify and validate the command line.

       -m	Return the command line which was used to create the file sys‐
		tem. The file system must already exist. This option  provides
		a  means  of  determining the command used in constructing the
		file system.

       -o	Specify	 FSType-specific options. See the manual page for  the
		mkfs module specific to the file system type.

USAGE
       See  largefile(5)  for  the  description	 of  the behavior of mkfs when
       encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).

FILES
       /etc/default/fs	       Default file system type. Default values can be
			       set for the following flags in /etc/default/fs.
			       For example: LOCAL=ufs

			       LOCAL	The default partition for a command if
					no FSType is specified.

       /etc/vfstab	       List of default parameters for each file system

ATTRIBUTES

NOTES
       This command might not be supported for all FSTypes.

       You  can use lofiadm to create a file that appears to a mkfs command as
       a raw device. You can then use a mkfs command to create a  file	system
       on that device. See lofiadm(1M) for examples of creating a UFS and a PC
       (FAT) file system (using mkfs_ufs(1M) and mkfs_pcfs(1M))	 on  a	device
       created by lofiadm.
