Criag,<br><br>In case you have 4 machines each with 4 drives.<br><br>you can replicate each drive of server1 with corresponding drive of<br>server2 using AFR.<br>you can replicate each drive of server3 with corresponding drive of<br>server4 using AFR.<br><br>So you have 8 AFRs.<br><br>You can use distribute (aka DHT) to aggregate the 8 AFRs.<br><br>Can you start with fresh backend directories and see if you still get<br>those errors? Because previous extended attributes on the directories<br>might be causing those errors.<br><br>If you still see the errors can you post your spec files?<br><br>Krishna<br><br>On Fri, Feb 6, 2009 at 9:57 AM, Craig Flockhart<br><<a ymailto="mailto:craigflockhart@yahoo.com" href="mailto:craigflockhart@yahoo.com">craigflockhart@yahoo.com</a>> wrote:<br>> Hi,<br>> I'm trying to come up with a working configuration for some machines as<br>> follows:<br>> - each is a client and a server and can see all the other
