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 i
Hope someone can help me define them.
First :
- 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. )
- define service which become online only on one system ( on startup ) , but can failover the other cluster node .( no failback )
- can I define bonding with ( mode1 –active/passive) with failback option ??
I attached the cluster.conf file
Thanks in advance
Shalom.
