Hi!
I found the solution to my problem, I had to install the following RPM
from the yum repository:
yum install fence-agents
It installed the following agents:
fence_ack_manual fence_brocade fence_egenera
fence_ilo_mp fence_nss_wrapper fence_sanbox2
fence_vmware_soap
fence_apc fence_cisco_mds fence_eps
fence_intelmodular fence_pcmk fence_scsi
fence_wti
fence_apc_snmp fence_cisco_ucs fence_ibmblade
fence_ipmilan fence_rhevm fence_virsh
fence_bladecenter fence_drac fence_ifmib
fence_kdump fence_rsa fence_vmware
fence_bladecenter_snmp fence_drac5 fence_ilo
fence_kdump_send fence_rsb fence_vmware_helper
I then configured stonith with something like this:
primitive shoot_serv2 stonith:fence_ipmilan \
params lanplus="true" login="user" passwd="*****"
action="reboot" ipaddr="*.*.*.*" pcmk_host_check="static-list"
pcmk_host_list="serv2" auth="password" timeout="30"
location shoot_serv2_on_serv1 shoot_serv2 inf: serv1
It seems to work well!
