Nothing....
Indeed these are the partitions that are now unused and used to be part
of the raid. Any idea what could have gone wrong when I migrated to from
FC3 to Centos?
I also changed the mobo of this machine and changed the CPU from single
to a dual core one. I assume support is in the kernel, so no special
actions should be needed to get this to work during boot up.
