[ClusterLabs] ClusterLabs.Org Documentation Problem?

[Jan Friesse]

> Thanks for the reply. Yes, it's a bit confusing. I did end up using the documentation for Corosync 2.X since that seemed newer, but it also assumed CentOS/RHEL7 and systemd-based commands. It also incorporates cman, pcsd, psmisc, and policycoreutils-pythonwhich, which are all new to me. If there is anything I can do to assist with getting the documentation cleaned up, I'd be more than glad to help.

Just a small correction.

Documentation shouldn't incorporate cman. Cman was used with corosync 
1.x as a configuration layer and (more important) quorum provider. With 
Corosync 2.x quorum provider is already in corosync so no need for cman.
