VxFS Version 5 disk layout
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. File sizes can be a maximum of 4 billion file system
blocks. For 64-bit kernels, the maximum size of the file system you can create
depends on the block size:
Maximum File System SizeBlock Size
4,294,967,039 sectors (≈4 TB)1024 bytes
