Hi, good morning,
1) If I don't set the switch parameter the system-config-cluster program
says: "A switch address must be provided for this Fence"... for me a
common address is a dotted quad expression.. what can I put instead of it?
2) For sure I've the fencedevice section configured.. I said the fencing
IS working.. the only thing is that I don't want the cluster restarts
nodes but switch them off! If the fencedevice section is missing,
fencing not works...
The problem actually is that I can't setup the fence system with a power
off of the nodes, even changing the fence_apc script. All the cluster is
working good in my test scenario apart that little thing!
Tnx
