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 indi-
     cated by  -F FSType.

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

     generic_options  are  independent  of  file   system   type.
     FSType-specific_options   is   a  comma-separated   list  of
     keyword=value pairs (with no intervening spaces), which  are
     FSType-specific.  raw_device_file  specifies the disk parti-
     tion on which to write the file system. It is  required  and
     must  be  the first argument following the  specific_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  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.

     -V       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 validate the command line.

     -m       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.

System Administration Commands                           mkfs(1M)

     -o       Specify  FSType-specific options.  See  the  manual
              page for the  mkfs module specific to the file sys-
              tem 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  exam-
                             ple: LOCAL=ufs

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

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

System Administration Commands                           mkfs(1M)

     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.
