The UDF file system, the industry-standard format for storing information on the optical media technology called DVD (Digital Versatile Disc or Digital Video Disc), is included in this Solaris release.
The UDF file system is provided as dynamically loadable, 32-bit and 64-bit modules, with system administration utilities for creating, mounting, and checking the file system on both SPARC and IA platforms. The Solaris UDF file system works with supported ATAPI and SCSI DVD drives, CD-ROM devices, and disk and diskette drives. In addition, the Solaris UDF file system is fully compliant with the UDF 1.50 specification.
The UDF file system support is provided in the following new packages:
SUNWudfr -- 32-bit kernel component
SUNWudfrx -- 64-bit kernel component
SUNWudf -- /usr component
In this Solaris release, the UDF file system provides the following features:
Ability to access the industry standard CD-ROM and DVD-ROM media when they contain a UDF file system.
Flexibility in exchanging information across platforms and operating systems.
The following features are not included in this UDF file system release:
Support for write-once media, CD-RW, and DVD-RAM, with either the sequential disk-at-once and incremental recording.
UFS components such as quotas, ACLs, transaction logging, file system locking, and file system threads, which are not part of the UDF 1.50 specification.
The UDF file system requires the following:
The Solaris 7 11/99 or the Solaris 8 release
Supported SPARC or Intel platforms
Supported CD-ROM or DVD-ROM device
This first Solaris UDF file system implementation provides:
Support for industry-standard read-write UDF version 1.50.
Fully internationalized file system utilities.
Create the /reconfigure file.
# touch /reconfigure
Shut down the system and turn off power.
# init 0
Connect the DVD-ROM device.
Turn on power to the system.
Verify the DVD-ROM device is automatically mounted.
$ ls /cdrom
If the system has both a CD-ROM and DVD-ROM device, the CD-ROM might be named /cdrom/cdrom0 and the DVD-ROM might be named /cdrom/cdrom1. If the system only has a DVD-ROM device, then try using /cdrom/cdrom0.
Display content with ls command.
$ ls /cdrom/cdrom1 Copyright filea fileb
Automatic display with the CDE file manager is not implemented yet. All other CDE file manager functions--drag and drop for copying and imagetool features--are available.
Display UDF file system parameters by using the mkfs command.
Create a UDF file system by using the mkfs command.
Create a UDF file system.
# mkfs -F udfs /dev/rdsk/device-name
Verify the UDF file system is created by mounting it. See "How to Mount a UDF File System" for more information.
See mkfs_udfs(1M) for more information.
Identify the UDF file system type by using the fstyp command.
Determine whether a file system is a UDF file system.
# fstyp -v /rdev/dsk/device-name
Check the integrity of a UDF file system by using the fsck command.
See fsck_udfs(1M) for more information.
Mount a UDF file system.
Mount a UDF file system.
# mount -F udfs /dev/dsk/device-name /mount-point
Verify the UDF file system is mounted.
# ls /mount-point
See mount_udfs(1M) for more information.
Unmount a UDF file system.
Create a file system and volume name for a UDF file system.
Create a file system and volume name for the UDF file system.
# labelit -F UDFS /dev/rdsk/device-name fsname volume
