Thanks, Ok, the debugging helps, now I can see that it's deleting different blocks for the same filename. Before I couldn't quite tell if it was making progress, but now I see it's deleting new locations. Looks like I have 100s of deletions coming up, thanks for automating this. Will report back, it looks like it may run for a few hours Afer that just do a check --repair or some other command options?
