[ClusterLabs] CentOS 7 - Corosync configuration

Fri Mar 6 14:05:26 UTC 2015

Hi,

anybody an idea? I think something in my corosync configuration is 
incorrect. The default Corosync configuration is working. But I want to 
use redundant rings and secuath should be set to on.

[root at linsrv006 ~]# cat /etc/corosync/corosync.conf
totem {
version: 2
secauth: off
cluster_name: databasecluster
transport: udpu
}

nodelist {
   node {
         ring0_addr: linsrv006.willi-net.local
         nodeid: 1
        }
   node {
         ring0_addr: linsrv007.willi-net.local
         nodeid: 2
        }
}

quorum {
provider: corosync_votequorum
two_node: 1
}

logging {
to_syslog: yes
}

[root at linsrv006 ~]# pcs status
Cluster name: databasecluster
