       mkfs - construct a file system

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

       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.

       The following are the generic options for mkfs:

	     Specify  the   FSType to be constructed. If  -F is not specified,
	     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.

	     Echo the complete command line, but do not execute	 the  command.
	     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 vali‐
	     date the command line.

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

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

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

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

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

       Manual pages for the  FSType-specific modules of	 mkfs.

       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.
