Hi, Four days and no replies... maybe you folks don't like me as the list has a healthy trafic on other topics ;-) Is there anything with my setup that shouldn't work? The problem is not with VMs because I tried the same configs with two real Dell servers and got the same problems. My iptables rules follow what's in RHCS manuals and wiki, and I found nothing new with netstat -a. Even them rgmanager only works correctly with iptables turned off (that is, iptables -F). If I start iptables (service iptables start) and then try to start cman and rgmanager, it won't work to flush iptables rules, I am forced to power off because rgmanager won't work and won't stop. My setup is simple: no clvm, no gfs, no gnbd. Just rgmanager and an http service configured as a script and an ip resource. But with iptables on, rgmanager won't relocate or failover the http service. More strange, system-config-cluster shows the service status only on the first node, on the second one it shows an emply service list. What can I do to debug the problem, as my /var/log/messages don't show any error messages, just what apears to be a regular two-node cluster startup?
