[Pacemaker] Two-Nodes Cluster fencing : Best Practices

[Bruno MACADRÉ]

Some modifications about my first mail :

After some researches I found that external/ipmi isn't available on my 
system, so I must use fence-agents.

My second question must be modified to relfect this changes like this :

     configure primitive pStN1 stonith:fence_ipmilan params 
ipaddr=192.168.100.1 login=ipmiuser passwd=ipmipwd
     configure primitive pStN2 stonith:fence_ipmilan params 
ipaddr=192.168.100.2 login=ipmiuser passwd=ipmipwd

Regards,
Bruno
