mkfs — build a Linux file system

[−V

filesys [blocks]
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.
−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.
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.
