After rebooting, cluster seems to be in reliable state:

And listing the services works: 
[root@qpid-mgmt-02 ~]# ccs -h qpid-mgmt-02 --lsnodes
qpid-mgmt-01: votes=1, nodeid=1
qpid-mgmt-02: votes=1, nodeid=2


So, it seems to traceback is limited to the cluster being out of whack

This error is occurring because ccs is not handling the comments in the cluster.conf file properly.

As a temporary workaround, removing the comments from the service & resources section will prevent this error from occurring.

Fix Upstream:

https://github.com/feist/ccs/commit/c672a2386688da1166898ce5e088951b07c04ba7


To test, use cluster.conf with these contents:
<?xml version="1.0"?>
<cluster config_version="20" name="a">
        <cman expected_votes="1" two_node="1"/>
        <clusternodes>
        </clusternodes>
        <fencedevices/>
        <rm>
                <resources>
                        <!-- COMMENT -->
                        <ip address="192.168.111.1" monitor_link="1"/>
                </resources>
        </rm>
</cluster>


And run: 'ccs -f /tmp/test.conf --lsservices', before the fix you get a traceback, after, you get this:

resources: 
  ip: monitor_link=1, address=192.168.111.1

Before Fix (using test_file created from cluster.conf in comment #5):
[root@ask-03 ~]# rpm -q ccs
ccs-0.16.2-75.el6.x86_64
[root@ask-03 ~]# ccs -f  test_file --lsservices
resources: 
Traceback (most recent call last):

After Fix (using test_file created from cluster.conf in comment #5):
[root@ask-02 ~]# rpm -q ccs
