Disk layout Version 9 enables support for data deduplication, file replication, and file compression. The Version 9 disk layout can support files and file systems upto 256 TB only. The maximum file system size that can be created is currently restricted to 6 gigabytes. For a file system to take advantage of greater than 1 terabyte support, it must be created on a Veritas Volume Manager volume. For 64-bit kernels, the maximum size of the file system you can create depends on the block size.
The Version 9 disk layout supports group quotas.
