Hi !
I've been using clusterip for a while now without any problem in
Active/Passive clusters (2 nodes).
Could you please explain, how could you use the ClusterIP in an
active/passive cluster? ClusterIP ist for the use in an active/active
cluster. See man iptables and look for the CLUSTERIP target.
Please explain more detailed.
What is your config?
What do you expect the cluster to do?
What really happens?
Where is the problem?
Maybe my explanation was not that clear.
Yes.
Here is my configuration
crm configuration show
node $id="17435146" pogcupsvr
node $id="34212362" pogcupsvr2
primitive apache ocf:heartbeat:apache \
params configfile="/etc/httpd/conf/httpd.conf" \
op start interval="0" timeout="40s" \
op stop interval="0" timeout="60s"
primitive clusterip ocf:heartbeat:IPaddr2 \
params ip="172.16.16.11" cidr_netmask="24" nic="eth0" \
meta target-role="Started"
...
property $id="cib-bootstrap-options" \
dc-version="1.1.7-2.mga1-ee0730e13d124c3d58f00016c3376a1de5323cff" \
cluster-infrastructure="corosync" \
stonith-enabled="false" \
no-quorum-policy="ignore"
rsc_defaults $id="rsc-options" \
resource-stickiness="100"
So I've started primary node (pogcupsvr). Configuration was checked and
ok. Then started the second node (pogcupsvr2). This time all the
configuration looked ok, no error but when I checked the network
configuration, eth0 was up on both nodes with same IP address of course,
instead of having it up only on primary node.
If that is your config than the start of the IP address on BOTH nodes is really
bad. This should not happen and is definitely an error.
BUT: I doubt that this is you complete config, because this would not work
anyway. The cluster would start the IP address on one node and the Webserver
in the other node.
Please paste the complete config. Then the community would be able to help.
