Could you please explain the rationale of using UFS+J for this large 
storage. Your published documentation states that you have reasonable 
redundancy in case of multiple disk failure and I wonder how you handle 
this with "plain" UFS. Things like avoiding hangs and panics when an 
disk is going to die.
