[Pacemaker] No communication between nodes (setup problem)

[Hans Bert]

Hello,

we had to move from Fedora 16 to Fedora 18 and wanted to set up Corosync with Pacemaker and PCS as management tool.
With F16 our cluster was running pretty good, but with F18 after 5 days we are reaching the point were we don't have
got ideas what might be the problem(s).


The cluster is build of two servers (server1=192.168.100.111; server2=192.168.100.112)

Based on the Howto for F18 with pcs we created the following corosync.conf:

totem {
  version: 2
  secauth: off
  cluster_name: mcscluster
  transport: udpu
}

nodelist {
  node {
    ring0_addr: 192.168.100.111
  }
  node {
    ring0_addr: 192.168.100.112
  }
}

quorum {
  provider: corosync_votequorum
}

logging {
  fileline: off
  to_stderr: no
  to_logfile: yes
  to_syslog: yes
  logfile: /var/log/cluster/corosync.log
  debug: on
  timestamp: on
}



After we started the server a status check shows us:


[root at server1 corosync]#pcs status corosync

The only warnings and errors in the logfile are:
