Hi Ken,
I've tried configuring without pcmk_host_list as well with the same result.
Stonith Devices:
Resource: NFS1 (class=stonith type=fence_xvm)
Attributes: key_file=/etc/cluster/fence_xvm_ceph1.key
multicast_address=225.0.0.12 port=NFS1
Operations: monitor interval=20s (NFS1-monitor-interval-20s)
Resource: NFS2 (class=stonith type=fence_xvm)
Attributes: key_file=/etc/cluster/fence_xvm_ceph2.key
multicast_address=225.0.1.12 port=NFS2
Operations: monitor interval=20s (NFS2-monitor-interval-20s)
Resource: NFS3 (class=stonith type=fence_xvm)
Attributes: key_file=/etc/cluster/fence_xvm_ceph3.key
multicast_address=225.0.2.12 port=NFS3
Operations: monitor interval=20s (NFS3-monitor-interval-20s)
I can get the list of VM's from any of the 3 cluster nodes using the
multicast address:
# fence_xvm -a 225.0.0.12 -k /etc/cluster/fence_xvm_ceph1.key -o list
NFS1 1814d93d-3e40-797f-a3c6-102aaa6a3d01 on
# fence_xvm -a 225.0.1.12 -k /etc/cluster/fence_xvm_ceph2.key -o list
NFS2 75ab85fc-40e9-45ae-8b0a-c346d59b24e8 on
# fence_xvm -a 225.0.2.12 -k /etc/cluster/fence_xvm_ceph3.key -o list
NFS3 f23cca5d-d50b-46d2-85dd-d8357337fd22 on
