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? Regards, Gary
