VxFS disk layout Version 5 is similar to Version 4. Structural files in Version 5 are the same in Version 4. However, the Version 5 disk layout supports file systems up to 32 terabytes. For a file system to take advantage of VxFS 32-terabyte 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. Files cannot exceed two terabytes in size. 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.
The Version 5 disk layout also supports group quotas. Quota limits cannot exceed one terabyte.
See About quota files on Veritas File System.
The Version 5 disk layout also supports up to 1024 access control list entries.
