NAME
     mkfs (generic) - construct a file system

SYNOPSIS
     mkfs [-F FSType] [-V] [-m] [-f] [-o specificoptions] special
          [operands]

DESCRIPTION
     mkfs constructs a file system on a special file; special must be the
     first argument and must be a special character device file (for exam-
     ple /dev/ios0/rsdisk000s1). The file system is created based on the
     FSType, specificoptions and operands specified on the command line.
     mkfs waits 10 seconds before starting to construct the file system.
     During this time the command can be aborted by entering a delete
     (DEL).

     operands are FSType-specific and the FSType specific manual page of
     mkfs should be consulted for a detailed description.

OPTIONS
     There are three types of option: genericoptions, otheroptions and
     specificoptions.

     genericoptions   Indicates options that are supported not only by the
                       generic but also by the FST-specific module of the
                       command (if that command exists).

     otheroptions     Indicates options that are supported only by the
                       generic command.

     specificoptions  Indicates suboptions that are supported only by the
                       FSType-specific module [see mkfs(1M-ufs) or
                       mkfs(1M-vxfs)] of the command. They are specified in
                       a comma-separated list and/or as keyword-attribute
                       pairs for interpretation by the FSType-specific
                       module of the command. These suboptions are speci-
                       fied via the -o option.

     The genericoptions are:

     -F   Specifies the FSType to be constructed. The FSType should either
          be specified here or be determinable from /etc/vfstab by matching
          the special with an entry in the table.

     -V   Echoes the complete command line, but does not execute the com-
          mand. The command line is generated by using the options and
          arguments provided by the user and adding to them information
          derived from /etc/vfstab. This option should be used to verify
          and validate the command line. When used with the FSType option,
          it passes the -V to the FSType-specific module for interpreta-
          tion.

mkfs(1M)                                                           mkfs(1M)

     -m   Returns 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. It cannot be used with genericoptions, specificoptions,
          or operands. It must be invoked by itself.

     -o   Specifies FSType-specific options.

     The otheroptions are:

     -f   Fast mkfs; skip the 10 second delay.

NOTES
     This command may not be supported for all FSTypes.

FILES
     /etc/vfstab
          list of default parameters for each file system
