Yes. Linear arrays have limited use in very specific scenarios.
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.
