Thanks, this now works, although I get poor write performance like a previous poster complained about: Around 7MB/s with "replicated distributed" and around 5MB/s with "distributed replicated pairs". This compares to 41MB/s with no replication.

So you have 8 AFRs. You can use distribute (aka DHT) to aggregate the 8 AFRs. Can you start with fresh backend directories and see if you still get those errors? Because previous extended attributes on the directories might be causing those errors. If you still see the errors can you post your spec files?
