Thanks for all the responses, Mark, Anthony and Wol. I have another hard drive on the way, just in case sda is truly dead. I had no idea that when a drive "dies" in a RAID5 array - nothing would notify me. I obviously have much to learn, really appreciate all the input from folks so far. I think I've provided the details of my setup (kernel, mdadm ver, distro, smartctl output, and mdadm -E output) - do let me know if I've left anything out. Left the machine alone this weekend and did not do anything with it.

I did try to reassemble last night (before I found the wiki and all) and it would assemble, but then it'll say it can't bring the array up 6 drives with 1 rebuilding, and the array thinks that there should be 8 drives. Does that mean I'm... screwed? Nope! Definitely not. Six drives, one rebuilding, array of 8. That means you have seven *working* drives out of eight. That's enough. Get the array working, it will continue rebuilding, and will leave you with seven drives out of eight. In other words, everything is CURRENTLY okay. But YOU HAVE NO REDUNDANCY. One more problem, and yes you are screwed. Which is why I say "wait for the experts". But, hardware permitting, I think this is an easy situation to recover.
