<font size=2 face="sans-serif">We are setup in a two node active/passive
cluster using pacemaker/corosync. We shutdown the pacemaker/corosync
on both nodes and changed the uname -n on our nodes to show the short name
instead of the FQDN. Started up pacemaker/corosync and ever since
we done that, when we run the crm_mon command, we see this below.</font>

<br><font size=2 face="sans-serif">We did edit the crm configuration file
to use short names for both nodes. We can ping both the short name
and the FQDN on our internal network and both come back with the right
IP address. We are running on RHEL 5. Anybody have any ideas
why the FQDN shows offline since this change since we configured pacemaker/corosync
to use short names? Is it grabbing it from internal DNS from the
IP address we have in the /etc/corosync.conf file? Everything seems
to be working correctly and failing over correctly. Should this be
something to worry about though or is it a display bug maybe? Below
is the corosync.conf file.</font>
