Could you please give a hint: how to use fencing in case the nodes are all
in different geo-distributed datacenters? How people do that? Because there
could be a network disconnection between datacenters, and we have no chance
to send a stonith signal somewhere.

Hi,
I tryed a network failure and it works.
During failure, each node try to fence other node.
When network come back, the node with network problem is fenced and reboot.
Moreover, the cman kill(cman) on one node, tipically node1 kill(cman) on
node2, so, I have 2 situations:
1) Network failure
That fence failed until the network came back makes your fence method
less than ideal. Will it eventually fence with the network still failed?
Most importantly though; Cluster resources blocked while the fence was
pending? If so, then your cluster is safe, and that is the most
important part.

In normal situation every node can in your file system, fence_scsi is
used when your cluster is in split-braint, when your a node doesn't

I have a question about stonith
In my scenarion , I have to create 2 node cluster, but I don't have any

So, there is an option to do something?
This is my scenario:
