RedHat AS 2.1 + ServiceGuard problem + cluster not start

[Laszlo Csizmadia]

I have RH AS 2.1 + MC/SG and a little problem.
[root@cluster1 root]# /etc/init.d/cmcluster.init start
1 XML error(s) found
tcp 0 0 0.0.0.0:5302 0.0.0.0:* LISTEN
udp 0 0 0.0.0.0:5302 0.0.0.0:*
cmrunnode : Unable to determine the nodes on the current cluster
cmrunnode : Either no cluster configuration file exists, or the file is corrupted, or cmclconfd is unable to run
Local node is not currently configured in a cluster
ERROR: Unable to join cluster

This is due to:
[root@cluster1 root]# /usr/local/cmcluster/bin/cmresmond --start
1 XML error(s) found
[root@cluster1 root]# ll /usr/local/cmcluster/conf/cmresmond_config.xml
-rw-r--r-- 1 root root 0 Dec 11 11:20

What should be in this xml config file? I didn't find any docs for this.

I will appreciate any help.
Thanks in advance.

this file contains parameters used by SG cmresmond service to monitor disks, services

these are exemple in /opt/cmcluster/conf/schemas

If you don't use it, you should disable those services in the cluster and package config files.

Denis,

I guess you mean /usr/local/cmcluster/conf/schemas. I can't really use these files:
[root@cluster1 root]# ll /usr/local/cmcluster/conf/schemas
total 12
-r--r--r-- 1 root root 1870 Dec 17 2002 ResMonConfigTypes.xsd
-r--r--r-- 1 root root 2904 Dec 17 2002 ResMonServerConfig.xsd
-r--r--r-- 1 root root 2820 Dec 17 2002 ResMonTypes.xsd

I guess these config files should be generated with cmconfigres create command.
When it fails give me this:
Failed running /usr/local/cmcluster/bin/cmviewcl -l package
Let's see:
[root@cluster1 root]# /usr/local/cmcluster/bin/cmviewcl -l package
cmviewcl : Cannot view the cluster configuration. Either this node is not configured in a cluster, or else there is some obstacle to viewing the configuration. Check the syslog file for more information. For a list of possible causes, see the ServiceGuard manual for cmviewcl.

And I'm not able to create the cluster config:
[root@cluster1 root]# cmquerycl -v -C /usr/local/cmcluster/conf/apache.config -n cluster1 -n cluster2 -q quorum

Begin checking the nodes...
Looking for other clusters ... Done
Error: Unable to establish communication to node cluster2: 19
Failed to gather configuration information.

Did anybody succeded to start MC/SG on RH AS 2.1?
Is this a bug or I totaly misunderstand the concept?

Believe it or not the default configuration of iptables and ipchains firewall can interfere with serviceguard.

service iptables stop on both machines and try again.

I have the same problem as those mentioned above, removed any & all association with firewall... so that is not the prob.
Anyone able to get this software to run.
Any help is greatly appreciated....
Thanks

One of the most common problems when the cluster cannot form (and one node cannot talk to another) is the use of the wrong network driver. Look carefully at the readme and use the driver listed there.
