[ClusterLabs] Two-Node OCFS2 cluster keep rebooting each other

After reading a bit and chatting at the #suse IRC channel, I'm starting to
think that for my use case, stonith would not be required.

Since there are only two nodes accesing the same disk, and no additional
redundant cluster channels, what will work meanwhile is disabling stonith.

I consider this also because the application that the Web server hosts, is
stateless, so if no incoming requests are received by the Load Balancer,
then, no write operations could be performed.

At the end, this was the way it worked before HA. What do you think?
