ZFS Checksum errors

[Steven Hartland]

Sorry not seen that before I'm afraid. Maybe you can use zdb to get more info but sounds like something is causing nasty issues.

I'd check your machine for bad hardware issues such as bad ram, cpu or cabling issues.

  Try waiting for the scrub to complete and see if its more helpful after that.
