I have done that prior to getting the status, several times actually,
tried to indicate that in my OP. IIRC, all checksums are zero after
clearing; after scrubbing, the total checksum goes back up to 4. The
error is not cleared, though.
Strange. I do recall that there was one OpenSolaris development release
which did produce spurious checksum errors which looked weird like
that. Hopefully you are not using that particular release.
I am using ZFS as it comes with the official FreeBSD 7.2 64bit, no
patches, no dev releases, all binary out of the box, nothing self-built.
IIRC, that's ZFS version 6.
Your 'zpool status' output did not indicate that a scrub was done.
You are correct, my mistake. I reproduced the 3 zpool command lines in
my OP from memory. I have gone through many clear/scrub/status,
export/import, wash/rinse/repeat cycles now, the 'last scrub' info must
have gone lost in one of them. A scrub on that pool takes ~8 hours, so I
refrained from running it again just for demonstration purposes.
Hmmm. Just as I want to double-check, I get this:
[u...@host ~]$ sudo zpool history
History for 'zpool01':

Sigh. Maybe I should take that as another indication that something is
just not right and I should rebuild the pool, afterwise there'll always
be that nagging thought if my data is actually safe...
