Hi all,
i am working on a two node squid cluster with heartbeat2 and squid3.
The cluster was installed on debian 5.02 i386. the system is up and
running - what is going well by now is: The two nodes are working as a
cluster with a secondary ip on their lan interface. squid3 is started
from the heartbeat daemon. if i shutdown one node, the squid and the
ip is brought up in the right way on the second node. hard shutdown of
the activ node also moves the resources. I used the main parts from a
prior post (but i attached the squid script and the xml what i
inserted to the debian default cib.
What is not working correct (imo) is: if you rename the squid.conf on
the active node (so squid is not able to start on it) heartbeat tries
to restart squid but does not move the resources. And the inserted
ping nodes seem to have no effect - disbaling the lan interface of a
active node, does not force the resources to move.
find attached my config:

logfacility local0
node proxy1 proxy2
bcast eth1
mcast eth0 239.0.0.2 694 1 0
ping 192.168.1.254 192.168.1.253
