Would you be able to direct me to some documentation for configuring STONITH based on my environment? The Clusters from Scratch document talks about a fence_ipmilan driver, which I seem to not have on my centos 6 install. I only show the fence_pcmk driver.
Reading the metadata for fence_pcmk, I don't quite understand how it should be configured.
