Hi Bill,

As far as I have experienced under pacemaker this is true in most cases.
EG: Two nodes running a master/slave httpd will fail over without fencing.

However, if for example your nodes are also using GFS2 and something
goes wrong then you will find your filesystem locked by DLM which will
obviously break fail over for services on that filesystem.

In short, best to configure fencing unless this is a lab environment
your willing to break!
