mkfs_udfs - construct a udfs file system


mkfs -F udfs [generic_options] [-o specific_options] raw_device_file


This is the universal disk format file system (udfs) -specific module of
the mkfs command. mkfs constructs a udfs file system with a root


See mkfs(8) for the list of supported generic_options.

The following options are supported:

-o specific_options
Specify a udfs-specific option. Specify udfs file
system specific options in a comma-separated list
with no intervening spaces. If invalid options are
specified, a warning message is printed and the
invalid options are ignored.

The following specific_options are available:

Print the file system parameters
without actually creating the file

Specify the label to be written
into the volume header structures.
Specify string as the name of the
label. If string is not specified,
a default string is generated in
the form of *NoLabel*.


The following operands are supported:

Specify the disk partition on which to write.

Specify the number of 512-byte blocks in the file


attributes(7), fsck(8), mkfs(8)


not currently a valid file system

The specified device does not contain a valid udfs file system.

Invalid size: larger than the partition size

Number of blocks given as parameter to create the file system is larger
than the size of the device specified.

is mounted can't mkfs

Device is in use, cannot create file system when the device is in use.

preposterous size

Negative size parameter provided is invalid.

sector size must be between 512, 8192 bytes

Sector size given is not in the valid range.

Volume integrity sequence descriptors too long
File set descriptor too long.

Not enough space to create volume integrity sequence or file set

mkfs: argument out of range

One of the arguments is out of range.

mkfs: bad numeric arg

One of the arguments is potentially a bad numeric.


You can use lofiadm to create a file that appears to a mkfs command (for
example, mkfs_pcfs or mkfs_ufs) as a raw device. You can then use a mkfs
command to create a file system on that device. See lofiadm(8) for
examples of creating a UFS and a PC (FAT) file system on a device created
by lofiadm.
