[Bug 919429] Re: Munin "IO Service Time" graph gives completely implausible numbers

[Tel]

Just for reference, here is a graph of IO operations, showing the
additional load. The green line is /dev/md0 but that is a RAID mirror of
/dev/sda and /dev/sdb so they are taking the load. NOTE: the load on
/dev/sdc is constant and would typically be the drive taking the most
load. This graph seems very plausible to me.
