Resizing a file system

You can extend or shrink mounted VxFS file systems using the fsadm command. The size to which file system can be increased depends on the file system disk layout version. A file system using the Version 7 or later disk layout can be up to 8 exabytes in size. The size to which a Version 7 or later disk layout file system can be increased depends on the file system block size.

See About disk layouts.
