<div>
<p class="MsoNormal">I previous posts on the forum someone stated that qdisk was needed in order to enable HA on a two-node cluster. My question is that I have found a thread (in another list) where they explain how to have fencing configured on a two node
cluster under cman:<o:p></o:p></p>

<div>
<p class="MsoNormal">The question is... Do we really need qdisk?. If so, I don't really understand how does HA-CMAN-qdisk interact to make things happen. I mean, from the previous link it seems that everything relating to managing fencing is provided by CMAN.
If so... what is the role qdisk plays here?.<o:p></o:p></p>
