  From guide you sent me, I understood that fencing to work well servers
should have IPMI available on motherboards.

  My client is going to purchase servers at Hetzner from their EQ-Line.
I asked their support if IPMI is available. Since my other client
already has server with 'em, I tried to install ipmi related packages
(like you specified in guide). IPMI service doesn't start, so I assume
it's not available or not turned on in BIOS.

  How would cluster work if no IPMI or similar technology is available
for fencing? In case one of nodes dies and no fencing is available,
cluster will hang until administrator does manual fancing?

  Best Regards,
  Nikola
