Hello,<br>
<br>
we had to move from Fedora 16 to Fedora 18 and wanted to set up Corosync with Pacemaker and PCS as management tool.<br>
With F16 our cluster was running pretty good, but with F18 after 5 days we are reaching the point were we don't have<br>
got ideas what might be the problem(s).<br>
<br>
<br>
The cluster is build of two servers (server1=192.168.100.111; server2=192.168.100.112)<br>
<br>
Based on the Howto for F18 with pcs we created the following corosync.conf:<br>
<br>
totem {<br>
version: 2<br>
secauth: off<br>
cluster_name: mcscluster<br>
transport: udpu<br>
}<br>
<br>
nodelist {<br>
node {<br>
ring0_addr: 192.168.100.111<br>
}<br>
node {<br>
ring0_addr: 192.168.100.112<br>
}<br>
}<br>
<br>
quorum {<br>
provider: corosync_votequorum<br>
}<br>
<br>
logging {<br>
fileline: off<br>
to_stderr: no<br>
to_logfile: yes<br>
to_syslog: yes<br>
logfile: /var/log/cluster/corosync.log<br>
debug: on<br>
timestamp: on<br>
}<br>
<br>
<br>
<br>
After we started the server a status check shows us:<br>
<br>
<br>
[root@server1 corosync]#pcs status corosync<br>
