Hi,
Are you sure multicast is working in your switch?
Openais uses it... I have had several really odd misbehaviours because of multicast not working...

Subject: Unable to retrieve batch 1493885544 status fromx.x.x.86:11111: module scheduled for execution
Hi All,
I'm trying to set up a 2-node cluster using luci. As of now, I have only configured it with a single service, with a single resource: an IP address, so I could test if the IP address fails over to the other node. So far, it doesn't.
In /var/log/messages of the first node, it says: "Unable to retrieve batch 1493885544 status from x.x.x.86:11111: module scheduled for execution"
It seems that each node is unaware of the other, "cman_tool nodes" says, respectively:
===<snip>===
Node Sts Inc Joined Name
1 M 48 2008-11-24 23:46:04 x.x.x.85
2 X 0 x.x.x.86
===<snip>===
Node Sts Inc Joined Name
1 X 0 x.x.x.85
2 M 72 2008-11-24 23:32:43 x.x.x.86
===<snip>===
My /etc/cluster/cluster.conf contains:
===<snip>===
<?xml version="1.0"?>
<cluster alias="binary.cluster" config_version="18" name="binary.cluster">
<fence_daemon clean_start="1" post_fail_delay="0" post_join_delay="3"/>
<clusternodes>
<clusternode name="202.81.160.85" nodeid="1" votes="1">
<fence/>
</clusternode>
<clusternode name="202.81.160.86" nodeid="2" votes="1">
<fence/>
</clusternode>
</clusternodes>
<cman expected_votes="1" two_node="1"/>
<fencedevices/>
<rm>
<resources>
<ip address="202.81.160.87" monitor_link="0"/>
</resources>
<service autostart="1" exclusive="1" name="binary.service" recovery="relocate">
<ip ref="202.81.160.87"/>
</service>
<failoverdomains/>
</rm>
</cluster>
===<snip>===
I've already tried some things mentioned in the list archives:
1. "ccs_test connect" returns "Connect successful." on both nodes.
2. Although I'm using IP addresses in cluster.conf, I've added hostname definitions in /etc/hosts on both nodes:
===<snip>===
x.x.x.85 node1.domain.com node1
x.x.x.86 node2.domain.com node2
===<snip>===
3. When I manually copy /etc/cluster/cluster.conf to both nodes and do a "cman_tool version -r <version_number>", luci shows both nodes' "Status" as "Cluster Member". But when I try to make any changes using luci, the second node becomes "Not a Cluster Member"; and doing a "Have node join cluster" doesn't make it a member.
I'm running on CentOS 5.2 with:
luci-0.12.0-7.el5.centos.3
ricci-0.12.0-7.el5.centos.3
cman-2.0.84-2.el5_2.1
rgmanager-2.0.38-2.el5_2.1
Any pointers on how to make this work?
TIA,
-eric
