VxFS disk layout Version 6 is similar to Version 5, except that Version 6 enables features such as multi-volume support, cross-platform data sharing, named data streams, and File Change Log. Structural files in Version 6 are the same in Version 5. The Version 6 disk layout can theoretically support files and file systems up to 8 exabytes (263). The maximum file system size that can be created is currently restricted to 235 blocks. 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 6 disk layout also supports group quotas.
See About quota files on Veritas File System.
Some UNIX commands may not work correctly on file systems larger than one terabyte.
