棘手的问题，关于vxfs

johnyou

The unit of allocation in VxFS is a block. Unlike some other UNIX file systems, VxFS does
not make use of block fragments for allocation because storage is allocated in extents that
consist of one or more blocks.
You specify the block size when creating a file system by using the mkfs –o bsize
option. The block size cannot be altered after the file system is created. The smallest
available block size for VxFS is 1K, which is also the default block size.
Choose a block size based on the type of application being run. For example, if there are
many small files, a 1K block size may save space. For large file systems, with relatively
few files, a larger block size is more appropriate. Larger block sizes use less disk space in
file system overhead, but consume more space for files that are not a multiple of the block
size. The easiest way to judge which block sizes provide the greatest system efficiency is to
try representative system loads against various sizes and pick the fastest. For most
applications, it is best to use the default values.
For 64-bit kernels, which support 32 terabyte file systems, the block size determines the
maximum size of the file system you can create. File systems up to 4 TB require a 1K block
size. For four to eight terabyte file systems, the block size is 2K, For file systems between 8
and 16 TB, block size is 4K, and for greater than 16 TB, the block size is 8K. If you specify
the file system size when creating a file system, the block size defaults to these values

VXVM 3.1.1的软件限制中没有这一项说明。也许是你的做法有问题。vxprint -ht贴来看看。

错误还一样吗？按我说的方法，有人做个4T的。就不是我自己做的了。错误贴上看看。
