Thanks Patrick for your reply. I know my original message was long, so perhaps it was missed, but I did run a consistency check, at least twice. However, after each CC run, we tested a dd_rescue attempt on the file in question and still had unreadable blocks. I was expecting one of two things: 1) the consistency check reporting back all sorts of problems, or 2) the unreadable blocks would go away. Neither was the case and hence I decided to reach out.
I had forgotten about the "action=exportlog", thanks for reminding me about that.
