I remember reading something recently (within the last year?) about smartmontools causing disks to go offline unnecessarily in some situation, i think due to a bug in the smart tools. I don't know if it's a certain version of smartmontools or combination of that and other things. Maybe you can try upgrade/downgrade of smart or temporarily disable smartd to see if it stops the disks from being taken offline.
