Hello.
Oops, an omission.
Here comes my Pacemaker config :

The STONITH resources are custom ones which use my provider SOAP API to
electrically reboot fenced nodes.
Concerning the web page you talked me about, I tried to insert the
referred environment variable, but it did not solved the problem :
root at Malastare:/home/david# crm_mon --one-shot -VroA
