VxFS Version 6 Disk Layout

VxFS disk layout Version 6 is similar to Version 5. 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). For a file system to take advantage of VxFS 8-exabyte support, it must be created on a VERITAS Volume Manager volume, and only on a 64-bit kernel operating system. The maximum file system size on a 32-bit kernel is still one terabyte. For 64-bit kernels, the maximum size of the file system you can create depends on the block size:

If you specify the file system size when creating a file system, the block size defaults to the appropriate value as shown above. See the mkfs(1M) manual page for more information.

The Version 6 disk layout also supports group quotas (see Quota Files on VxFS).
