Multiterabyte UFS file systems include the following features:
The ability to create a UFS file system up to 16 terabytes in size.
The ability to create a file system less than 16 terabytes that can later be increased in size up to 16 terabytes.
Multiterabyte file systems can be created on physical disks, Solaris Volume Manager's logical volumes, and Veritas' VxVM logical volumes.
Multiterabyte file systems benefit from the performance improvements of having UFS logging enabled. Multiterabyte file systems also benefit from the availability of logging because the fsck command might not have to be run when logging is enabled.
When you create a partition for your multiterabyte UFS file system, the disk will be labeled automatically with an EFI disk label. For more information on EFI disk labels, see SPARC: Multiterabyte Disk Support With EFI Disk Label.
