cat /proc/mdstat: shows the active and inactive RAID sets.
mdadm (mdctl in GOS 4.x): assemble/start/stop/rebuild RAID sets. Use this to manually start a RAID if it doesn't start automatically. Might need to be used in the case of a failed drive or two or three. Note that md100root and md101swap are the only RAIDs that need to be active for the server to boot.
From here out, you're going to have to perform somewhat advanced Linux troubleshooting. I think you're experiencing a failing drive though.

Great, thank you. I will be trying this tonight.
so, if I run 'mount' and I see that both md100root and md100swap are mounted, then I am going to want to try mdadm and rebuild the raid? (rebuild as in what? I dont want to lose any data.....)
if I run mount, and md100root is not mounted, I will try removing drive 1 and letting it boot off drive two. If that works, then I will put in my spare HDD i have back in drive 1, so it can rebuild itself, and RMA drive 1 .... correct?
what would I be looking for in the cat /proc/mdstat command? Just to make sure md100root is active (if it does show as mounted) ?
Lastly, what is md100root is shown, and md101swap isnt?
Thanks for all your help so far!!!
