Normally one would only use a linear array that consists of hardware or software RAID constituent devices, such as the example in my previous email. At minimum a linear array should be composed of multiple mirrored drives (RAID1). As Robin mentioned, if you can't do redundancy for some reason, simply format each disk with your favorite filesystem and mount those filesystems somewhere in your UNIX directory tree. -- Stan
