Yersterday i toubled with system crash due to an md device that stopped due to an error on a single block (sata controller). Starting from a live rescue cd to analize the situation I found that the array thought the good disk was the one had the block failure, so that reconstruction arrived at 75% and then restarted (I saw that happending). I eliminated the bad disk and the other couldn't start complaining it was a spare one (but no one was configured as spare...) so that there where no good disk. I had to turn it into a normal /dev/sda disk to be able to start the system. My question is if there is a way to convince a device that it is the good device w/o destroying the array and how it can happen that an array component turns into a spare one. What should I have one?
