Hello list
I'm trying to setup a 3 nodes Cluster with 2 failover Domain for an HA
mail solution.
I want 1 run active for the Imap server in the Imap Failover domain , 1
node active for the Smtp in the Smtp Failover domain and the 3rd in the
2 failover domain as a backup node.
I run Centos 5.3
My fence device is a wti power switch
My cluster.conf is in attachement
My SMTP service is composed of:
1 IP
1 amavisd scritp
1 postfix script
2 NFS mount for postfix and amavis
If I manually kill the postfix master process (to simulate a crash), my
node is not fence and the logs said:

service:Imap
centos-imap2.ill.fr started
service:Postfix
(centos-smtp1.ill.fr) failed
So I have to disable the Postfix servcie with:
clusvcadm -d Postfix
and re-enable
clusvcadm -e Postfix
Could you explain my why my original smtp node is not fenced and why my
service is not start on the 2nd node ???
Is there a way to force the fencing ???
