[TriLUG] Adding HDD to a Software RAID - Possible?

[James Brigman]

Some reasonable assumptions:
FC4 uses LVM by default, 
4-200GB drives would most likely be ATA

Answer can be found here:
http://www.tldp.org/HOWTO/LVM-HOWTO/

Problem, though: how will he add a 5th drive if the system has two IDE
buses, each with two drives? He won't, unless he adds a PCI ATA card to
the system. In that case, the person needs to know a bit about how the
drive devices are named.
