Hi,
I noticed recently by accident that when I read/write from the oldest raid
disks I have - only one of the tray leds blinks. Of course the led could be
damaged, but rather not, so looking into it I found that both disks in
question return same UUID. So I am concerned now that I don't have any true
RAID there and that there is very important data on those disks.
How is this possible and how to solve it - I would simply add 3rd 500MB disk
to the raid and remove one of the others, but still what is the impact of
this (stupid) coincidence ...
