Veritas File System 5.0 Administrator's Guide (September 2006)

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
8,589,934,078 sectors (≈ 8 TB)2048 bytes
17,179,868,156 sectors (≈ 16 TB)4096 bytes
34,359,736,312 sectors (≈ 32 TB)8192 bytes
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.
The Version 5 disk layout also supports up to 1024 access control list entries.
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 (2
63
). For a file system to take advantage
of VxFS 8-exabyte 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:
Currently-Supported Maximum File System SizeBlock Size
68,719,472,624 sectors (≈ 32 TB)1024 bytes
137,438,945,248 sectors (≈ 64 TB)2048 bytes
274,877,890,496 sectors (≈ 128 TB)4096 bytes
549,755,780,992 sectors (≈ 256 TB)8192 bytes
Note: Sector size in
bytes specified by
the DEV_BSIZE
system parameter.
If you specify the file system size when creating a file system, the block size
defaults to the appropriate value as shown above.
