Quoting Zev Weiss <zwe...@scout.wisc.edu>:
Hi,
Ken, Mark -- any further information on the write performance
problem, and/or a solution to it?
I'm running 8.3.7 at the moment, I think I'm going to try updating
to 8.3.11 and/or 8.4 and see if it magically fixes anything (unless
there are further suggestions on other things to try).

I've put together a quick test cluster. DRBD does well on the initial
disk sync. I just went back and looked at the graphs to make sure it
wasn't my imagination. I'm beginning to think it has something to do
with the interaction of DRBD/LVM2/GFS2 that is not happy. I did most
of the tweaks I could find and it added up to 50% increase, but going
from 1.5M to 2.0M isn't exactly thrilling.
