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: Jul 6 10:00:40 centos-smtp1 clurgmgrd: [4228]: <info> Executing /etc/init.d/postfix status Jul 6 10:00:40 centos-smtp1 clurgmgrd: [4228]: <err> script:postfix: status of /etc/init.d/postfix failed (returned 3) Jul 6 10:00:40 centos-smtp1 clurgmgrd[4228]: <notice> status on script "postfix" returned 1 (generic error) Jul 6 10:00:40 centos-smtp1 clurgmgrd[4228]: <notice> Stopping service service:Postfix Jul 6 10:00:40 centos-smtp1 clurgmgrd: [4228]: <info> Executing /etc/init.d/amavisd stop Jul 6 10:00:40 centos-smtp1 kernel: do_vfs_lock: VFS is out of sync with lock manager!
