Kevin, Did you fix your ZFS CRC errors? I responded to your thread, but no-one got back to me. I'm gonna start another thread later. This time I re-made the zpool in 8 compatible with 7. Once the errors started showing up in 8 I moved back to 7, on the same hardware, to perform the scrub to prove the problem is with 8. The 1st scrub in 7 found some errors, but of course it would if 8 had messed up the data. Removed the few unimportant bad files (all were in snapshots). Just performing the 2nd scrub in 7 now. If this comes back with no errors, then we have stronger proof that there is some wrong, which seems quite intermittent, in 8 that randomly writes bad data. Cheers.
