Hi, You have the same problem as I had before: http://lists.linux-ha.org/pipermail/linux-ha/2010-April/040035.html
I think the solution is using UPS or PDU for STONITH device. The problem is that STONITH is treated as a resource. If it failed for any reason, the cluster will simply fail too. Therefore to prevent the failure in your scenario from happening, you need your STONITH devices and host machines to have separate power supply.
