Hi,
I've seen some discussions about this, but I'm still confused.
I'm using the drac5 stonith plugin from Thomas Paschy (thanks
thomas) but I don't know how to cofigure it to work fine.
We have a cluster with 2 nodes, each one with its public address,
and each one with a drac5 device with a private address;
le'ts call them node1, node2, node1_drac and node2_drac. So node1
can make a reset to node2 connenting to node2_drac,
and node2 can make a reset to node1 connenting to node1_drac
So we have created two stonith resources called stonith_node1_drac
(with node1_drac address) and stonith_node2_drac (with
node2_drac address); stonith_node1_drac needs to run on node node2
because it is node2 which can reboot node1, an stonith_node2_drac
needs to run on node node1 because it is node1 which can reboot node2
If we started this way, they starts ok. But when we forced a stonith
condition on node2 (killing heartbeat) node 1 is not able to reset
node2; we got
this on logs:

It seems that there is something messy with the addresses.
Can anyone help?
not without logs, configurations and the version your using
We are using heartbeat 2.1.2
I think I have understood the problem. When node1 wants to stonith node2
and asks its stonith device which hosts it can stonith, device
answers it can stonith node2_drac, but not node2; so node1 doesn't know
how to stonith node2
I fixed the problem adding an extra parameter "hostname" to drac5 plugin
so it can returns hostname when asked for which host it fences and
it uses ipaddr to access to the drac of the host (original drac5 plugin
have only ipaddr,login and password parameters). And it works!
But I suppose that there is a similar problem witch drac3 plugin
included in heatbeat; so how can people use it ? Does anybody know?
