NAME

mkfs_udfs - construct a udfs file system

SYNOPSIS

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

DESCRIPTION

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

OPTIONS

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:

N
Print the file system
parameters without actually
creating the file system.


label=string
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*.

OPERANDS

The following operands are supported:

raw_device_file
Specify the disk partition on which to write.


size
Specify the number of 512-byte blocks in the file
system.

DIAGNOSTICS

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
descriptor.

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.

NOTES

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.
