ZFS Checksum errors

[Steven Hartland]

It could also be issues with the hardware above the raid controller, e.g. main memory.

Hardware raid check doesn't really tell you too much where as zfs checks are end to end so
will detect intermediate issues like memory or cpu problems.

We've even had a few issues in the past where the raid controller thought everything was
fine but zfs was complaining and it did turn out to be disks on the way out.

So at this point I wouldn't rule out anything.

To be honest, if ZFS says you've got a ton of checksum errors, I would
strongly bet in favor of your data being damaged over a bug in ZFS.

What're the underlying disks and RAID card?
