Greetings, listers,
We've got an on-going issue with i/o contention. There's the obvious problem
that we've got a whole lot of things all writing to the same partition. In
this case, there's just one big chunk of RAID 5 disk on a single controller so
I don't believe that making more

I like the suggestions Matthias makes; those suggestions have worked
well for us.
RRD updates are very expensive - I am pretty sure without knowing
anything more about your system that the RRD writes are causing most
of the I/O load.

At the moment I'm concerned about the graphdata, but because I can only see
i/o utilization as an aggregate, I can't tell what is the worst component on
that filesystem -- status.dat updates? graph data? writes to the var/spool
