Hmm. Interesting.

I have re-scrubbed pool that I referenced. I haven't gotten another
error in the metadata.

Perhaps the cause of the corruption is still active.

The circumstances that lead up to the discovery of the error are
different for you and me. The server that I encountered it on was
running fine for months, it was only after the crash/hang because of
attempting to add a bad drive to the pool that I encountered the issue
which was found on boot in my case.
