I've recently purchased a ReadyNAS Ultra 6 along with 6 2 Tb Seagate ST2000DL003 disks (which are on the HCL). I've set up the NAS in a dual redundancy X-RAID2 configuration and have starting copyi...
I've experienced the exact same problem, but with another Seagate model (ST31500341AS). They worked flawlessly with my Duo but when I switched to an Ultra 2 the problems started.
My system.log is filed with cycles like this one:

Two days ago disk 2 turned "dead"/grey in Frontview, but came back alive after I pulled it out, rebooted and then put it back in. After a few hours it hade re-synced.
This has now happened again, but now disk 2 is still showing in Frontview as dead, without being present in the system! I can't make the system identify the slot as empty, and then re-sync as I insert the drive.
What should I do? Could a reboot with both of the inserted do any harm?
Cheers,
Peter
