Just to second that I'd really appreciate this too. I've been trying to setup a couple of machines on a not-too-reliable 100Mbs network with a set of partitions each, mirror the same data. Thus far I've been managing this with scripts that do rsync. With glusterfs I used unify for the 4 partitions on each machine and then afr'd the two unified disks but was told that this is not a reliable way of doing things and that I'd run into problems when one host goes down. What you are talking about seems to satisfy exactly what I am trying to do and would be very convenient. If there is a way to do this currently with glusterfs I'd definitely like to hear about it. cheers, prabhu
