Name
mkfs — build a Linux file system
Synopsis
mkfs [−V] [ −t fstype ] [fs−options]
filesys [blocks]
DESCRIPTION
mkfs is used
to build a Linux file system on a device, usually a hard disk
partition. filesys is
either the device name (e.g. /dev/hda1, /dev/sdb2) or the mount point (e.g.
/, /usr, /home)
for the file system. blocks is the number of blocks
to be used for the file system.
The exit code returned by mkfs is 0 on success and 1 on
failure.
In actuality, mkfs is simply a front-end for the
various file system builders (mkfs.fstype) available under Linux.
The file system-specific builder is searched for in a number
of directories like perhaps /sbin, /sbin/fs, /sbin/fs.d, /etc/fs, /etc
(the precise list is defined at compile time but at least
contains /sbin and /sbin/fs), and finally in the directories
listed in the PATH environment variable. Please see the file
system-specific builder manual pages for further details.
OPTIONS
−V-
Produce verbose output, including all file
system-specific commands that are executed. Specifying
this option more than once inhibits execution of any
file system-specific commands. This is really only
useful for testing.
−tfstype-
Specifies the type of file system to be built. If
not specified, the default file system type (currently
ext2) is used.
fs-options-
File system-specific options to be passed to the
real file system builder. Although not guaranteed, the
following options are supported by most file system
builders.
−c-
Check the device for bad blocks before building the
file system.
−lfilename-
Read the bad blocks list from filename
−v-
Produce verbose output.
BUGS
All generic options must precede and not be combined with
file system-specific options. Some file system-specific
programs do not support the −v (verbose) option, nor return
meaningful exit codes. Also, some file system-specific
programs do not automatically detect the device size and
require the blocks
parameter to be specified.
