This is the configuration: root on a raid 1 on top of an lvm consisting of two
PVs (two 1TB Western digital hdds). This is what I'm experiencing: While
mounted, the system suddenly will become unresponsive / freeze for a period of
up to 20-30 seconds. Running iostat on a 10 second interval revealed iowait
percentages up to 99% over a 30 second period (max). Looking at iotop output I
could see the following at the top of the list during the spikes:430 be/4
