NAME

mkfs (generic) − construct a file system

SYNOPSIS

/usr/sbin/mkfs [−F FStype] [−o specific_options] [−V] special [operands]

/usr/sbin/mkfs [−F FStype] [−m] [−V] special

DESCRIPTION

The mkfs command creates a file system by writing on the special file special.

Options

mkfs recognizes the following options:

−F FStype Specify the file system type on which to operate (see fstyp(1M) and fs_wrapper(5)). If this option is not included on the command line, then the file system type is determined from the file /etc/fstab by matching special with an entry in that file.  If there is no entry in /etc/fstab, then the file system type is determined from the file /etc/default/fs. 

−m Display the command line that was used to create the file system.  The file system must already exist.  This option provides a means of determining the parameters used to construct the file system. 

−o specific_options
Specify options specific to the file system type. specific_options is a list of suboptions and/or keyword/attribute pairs intended for an FStype-specific module of the command. See the file system specific manual entries for a description of the specific_options that are supported, if any. 

−V Echo the completed command line, but perform no other action.  The command line is generated by incorporating the specified options and arguments with other information derived from /etc/fstab.  This option allows the user to verify the command line. 

EXAMPLES

Execute the mkfs command to create an HFS file system on /dev/dsk/c1d2s0:

mkfs −F hfs /dev/dsk/c1d2s0 1024

Execute the mkfs command on an HFS file system, /dev/dsk/c1d2s0, to recreate the command that was used to create the file system on /dev/dsk/c1d2s0:

mkfs −F hfs −m /dev/dsk/c1d2s0
