I would define a pingd resource to check the connectivity, and then base the IP
(and other resources) on the value determined by the pingd resource.
For example we have (not actually used yet, displayed by "crm_mon -1Arfj"):
Node Attributes:
* Node: h16:
* val_net_gw1 : 1000
* Node: h18:
* val_net_gw1 : 1000
* Node: h19:
* val_net_gw1 : 1000
So all three nodes can read gateway1 (gw1).
The configuration (crm shell syntax):
primitive prm_ping_gw1 ocf:pacemaker:ping params name=val_net_gw1 dampen=120s
multiplier=1000 host_list=...
op start timeout=60 interval=0 \
op stop timeout=60 interval=0 \
op monitor interval=60 timeout=60 \
meta priority=4500
clone cln_ping_gw1 prm_ping_gw1 \
meta interleave=true priority=4500
