RAID 6 4+2, LVM (single volume), 32kb stripe size (=> full stripe: 128kb), agcount=4 Except for the stripe size, the same config I had originally. The only instance of really poor behavior is with the (artificially) fragmented free space. I have moved everything elsewhere for a while, so I can once again do some testing that involves destroying and rebuilding everything. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
