[CentOS] Partitionable Raid

[Billy Crook]

If sda fails outright, sdb will BECOME sda. This is usually the case
when a "drive fails".

If sda is skillfully overwritten in specific places with the intention
of producing a curcumstance in which Linux kernel raid will fail, then
Linux kernel raid will fail.
