Re: lost with degraded RAID1

Ok, I did nuke it now and created the fs again using 3.12 kernel. So
far so good. Runs fine.
Finally, I know its kind of offtopic, but can some help me
interpreting this (I think this is the error in the smart-log which
started the whole mess)?

Error 1 occurred at disk power-on lifetime: 2576 hours (107 days + 8 hours)
  When the command that caused the error occurred, the device was
active or idle.

  After command completion occurred, registers were:
  ER ST SC SN CL CH DH
  -- -- -- -- -- -- --
  04 71 00 ff ff ff 0f  Device Fault; Error: ABRT at LBA = 0x0fffffff
= 268435455

  Commands leading to the command that caused the error were:
  CR FR SC SN CL CH DH DC   Powered_Up_Time  Command/Feature_Name
  -- -- -- -- -- -- -- --  ----------------  --------------------
