Thanks Martin! It works now.

Red Hat ships the following in 6.4: (not quite sure how that maps to your
versions, but it's old!)
rpm -qi ctdb

Version     : 1.0.114.3                         Vendor: Red Hat, Inc.

Thanks. I updated that range.

This seems to be the trick. I can always ping that IP as I move it from
host to host.
