Pit, Changing from an internal to external log is indeed a pain. And switching back is a bigger pain. Can you try changing you i/o scheduler as a first test. I forgot about that before and you seem to be using defaults for everything. You can do this on the fly. To see what you're using: cat /sys/block/md0/queue/scheduler (I think you said md0, if not just look in /sys/block and get the right device.) If you have [cfq], get rid of that via one of these commands: echo noop > /sys/block/md0/queue/scheduler or echo deadline > /sys/block/md0/queue/scheduler I think both noop and deadline will be fine, but CFQ is a horrible choice for XFS.
