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. Cheers, Wol
