Well, here is what I learned. Some more info about the system. It
has 4 250 GB disks. I set up the partitions as software RAID 5.
When I tried to boot, it could not find any of the disks. I tried
changing boot order to each one of the four disks and it just never
booted. I suspect I could have spent some time and gone through a
rescue of sorts with a Live CD, but considering my options I
decided to reinstall. The main thing on this system was an Oracle
10G R2 database. That was on a RAID partition by itself. Once
in CentOS install, it recognized all of the raid partitions. I
was able to save the partition with the Oracle database plus
(I thought) my home partition. The first time I brought the system
up, I realized I had made a mistake and substituted my root partition
for my home partition. Ooops. My own fault. Had I written down
the md device for each partition I would not have had to restore the
home partition. Plus I had a great deal of cleanup in my new
home partition. I was able to easily recover the Oracle database
if anybody wants to know that, contact me off-list. As a whole it
was pretty painless and could have been more so had I written down
the partition names.
