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

[Paul Morgan]

Can you post your configs?

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.
