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(1M) 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  inter-
			       vening 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(1M) for examples of creating a UFS and a PC (FAT) file system on a
       device created by lofiadm.
