VxFS disk layout Version 8 is similar to Version 7, except that Version 8 enables support for file-level snapshots. The Version 8 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 8 disk layout 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.
