Hello,
First of all, thank you very much for your quickly reply.
Your advice has made me thinking about the energy problem and its
relation with stonith. In my case, I use two machines with ILO-similar
system (like HP servers) and two power supplies.
Really, it's a very strange event that the two power supplies will fail
together. The another case would be the motherboard will get seriously
damaged.
In any case, I understand I'll need a third element (independent of both
machines) to ensure that stonith works fine. Maybe something like an UPS
or an advanced power supply line.
I'll try to investigate about this a little more. Again, thank you a lot
for your help.
Cheers,
