When I disconnect the heartbeat from one of the servers, whether

acquires both floating IP addresses and therefore causes much grief

ideas?
I'm guessing you have multiple NICs and that you're creating a split
brain situation.
Your ping nodes wont help if both machines can see them but not each
other.
Here is node 1's ha.cf:
#debugfile /var/log/ha-debug
logfile /var/log/ha-log
logfacility local0
keepalive 2
deadtime 30
warntime 10
initdead 60
udpport 694
ucast eth2 10.0.0.2
auto_failback on
ping_group group1 10.220.3.50 10.220.3.55
apiauth client-name gid=haclient uid=hacluster
apiauth ipfail gid=haclient uid=hacluster
max_rexmit_delay 10000
hbgenmethod time
node node1.server.com
node node2.server.com
Here is node 2's ha.cf:
#debugfile /var/log/ha-debug
logfile /var/log/ha-log
logfacility local0
keepalive 2
deadtime 30
warntime 10
initdead 60
udpport 694
ucast eth2 10.0.0.1
auto_failback on
ping_group group1 10.220.3.50 10.220.3.55
apiauth client-name gid=haclient uid=hacluster
apiauth ipfail gid=haclient uid=hacluster
max_rexmit_delay 10000
hbgenmethod time
node node1.server.com
node node2.server.com
The IP address for the heartbeat on node1 is 10.0.0.1 and the
heartbeat on
node2 is 10.0.0.2. The ping_group are servers within the
infrastructure
that are extrememly reliable. Still, I am at a complete loss.
Any help will be greatly appreciated.
Best regards,
Brian Klauss
