[Linux-cluster] cman not looking at all valid interfaces

[Celso K. Webber]

Hi Simmons,

While we wait for your configuration, please check if you did use a fully qulified domainname in cluster.conf. I had problems with that in the days of RHEL 5.0 and 5.1, so nowadays I always setup my cluster.conf using names like "nodeX.localdomain" and map these names to the IP addresses of my heartbeat network.

Please try this and tell us if it works, ok?

Regards, Celso.

Subject: [Linux-cluster] cman not looking at all valid interfaces


Hi, 
cman appears to not scan for interfaces correctly on my RHEL 5.3 64bit cluster.  When I change /etc/hosts and /etc/cluster/cluster.conf to use names "mynode1" and "mynode2" cman boots up correctly and I get a good cluster. 

If I change my configuration to use the interfaces named "mynode1-clu" and "mynode2-clu" which are defined in /etc/hosts I get an error:

Cman not started: Can't find local node name in cluster.conf /usr/sbin/cman_tool: aisexec daemon didn't start

However, if I do `hostname mynode1-clu` on the first node and `hostname mynode2-clu` on the second node and then restart cman I get a good cluster.  I think this proves that my -clu interfaces are valid and properly defined in /etc/cluster/cluster.conf.  

This node was created from a disk clone of another cluster.  Are there any cluster files that would retain system name or interface information?  I have triple checked my /etc/hosts, /etc/sysconfig/network /etc/sysconfig/network-scripts/*eth* , /etc/nsswitch.conf, /etc/cluster/cluster.conf and dns files.

Any suggestions would be appreciated.
