Features of Multiterabyte UFS File Systems

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.

• UFS logging is enabled by default on file systems greater than 1 terabyte. 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.
