Resizing a file system

You can extend or shrink mounted VxFS file systems using the fsadm command.Use the extendfs command to extend the size of an unmounted file system. A file system using the Version 4 disk layout can be up to two terabytes in size. A file system using the Version 6 disk layout can be up to 8 exabytes in size. The size to which a Version 6 disk layout file system can be increased depends on the file system block size.

See VxFS Version 6 disk layout.

See the fsadm_vxfs(1M) manual page.
