[GLLUG] Seemless addition of a hard drive?

[Benjamin Minshall]

Dan,

It sounds like what you need is Logical Volume Management (LVM) or 
Multi-disk (MD), but I suspect that LVM will more easily solve your 
problem.  It has the capability of spanning a large virtual filesystem 
over several physical disks.
