Hello !!!!

Hello !!!

I build Redhat cluster suite 5.3 with latest cman,openais,rgmanager rpms.

The hardware is dell r610 with  fence_drac5             .

Lvm is configured as HA-LVM.

The cluster is working properly , but customer asked for some features which

Hope someone can help me define them.

First :

   1. if there is a network fail on one system , Customer ask for 30 sec
   before fencing

      The failing system ,& if network is up again – not to fence the system
at all.

( each time the network fail, the  fenced immediately. )

   1. define service which become online only on one system ( on startup ) ,
   but can failover the other cluster node .( no failback )
   2. can I define bonding with ( mode1 –active/passive) with failback
   option ??

I attached the cluster.conf file

Thanks in advance
