Yes, once they have changed to the bad value, they don't move again that I've seen (done several trials over the past few days). > If you stop the array and run 'mdadm -E' on the drives, what values do > they have now. I'll test to see if they actually change values, but I can say for certain that they are still invalid checksum, i.e. once I stop the array I have to assemble it with -U resync to get it back online. (and it of course rebuilds) I'm starting to suspect the card's BIOS; it might either be bad or be some version which interacts strangely with the sata_sil driver. I am going to hunt for a flash update for it soon. Thanks for the reply! -- Josh Litherland (josh@temp123.org)
