[Linux-cluster] Some problems using fence_vmware_ng under ESXi 4

[Jan Friesse]

Carlopmart,
it's not problem of fence_vmware_ng and definitively not malfunction.
Cluster is trying to keep all possible nodes going. So what will happend:
- You will boot node01
- This will start fencing, and finds out, that node02 isn't running (is
falled, ...) -> fence node2
- Node2 is fenced and starts

Regards,
  Honza
