Disk layout Version 10 enables support for SmartIO and maxlink. The Version 10 disk layout can support files and file systems upto 256 TB only. The maximum file system size that can be created is currently restricted to 6 gigabytes. 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 10 disk layout supports group quotas.The vxfsconvert (1M) command is used to upgrade ext2 or ext3 file systems to the Version 10 disk layout when the file system is not mounted.
