The CKSUM errors from the zpool status output.  They are
indicative of underlying problems.  gpt/drive-07 has a low count
so it's possibly not a major problem, but gpt/drive-08 and 
gpt/drive-09 both have a significant number.  I find it a bit
curious that both drives in the mirror have similar number of
errors.  Possibly indicating data pathing errors.

I presume you are using ECC memory?

Gary
