Guys, I'm not sure how appropriate this question is for this forum, but since my problems are occurring on my linux system, I'm hoping someone can help. Recently I have had a rash of disk failures on my home server. One of them was an SSD 120G drive, a Samsung EVO 840. Then a seagate drive. The this which is puzzling me is that I have all my drives tied into raid arrays of various sorts in order to protect myself from disk failures. But the odd thing is that when I have my disk failures, it affect more than one drive in the array knocking out the whole raid array. what I've had to do is boot up using a live fedora image and then issue mdadm commands to restore the array. In one case, it was only one disk which was bad in the array, even though 2 disk's were kicked out. I had to reassemble the array to get it back up in degraded mode, after which replacing the one drive got it back up. In another case, two SSD drives went out, killing my raid 1 array (mirror mode). Again, mdadm'ing getting it back, and only replacing one SSD drive got the system going. Then again last night, my SSD raid 1 array kicked both drives out, but I was able to reassemble it without replacing drives. All this has occurred within one week! I've owned the system for like 7 years and never a glitch, until now. So, is it really the drives? could it be my motherboard or SATA controller on the motherboard is going bad? Bad power supply? Should I consider replacing the motherboard? Or am I just having a bad raid week? thanks. Steve.
