We got it up and running again. I don't remember what we did though. We've been going on no sleep all week trying to setup a new server and right before the old one crashed we were all ready to go home and take a little rest. Thanks again. --Ken - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html

hardware raid 5 and software raid 0 stripe broke.
We have a Linux box running redhat 7.2 We have two hardware controllers in it with about 500gig's each. They're raid 5. We were using a software raid to combine them all together. 1 hard drive went down so we replaced it and now the system won't boot. We have used a Knoppix boot cd to get into a linux system. We can see /dev/sda1 and /dev/sdb1. However, /dev/md0 cannot be accessed.
