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.

The documentation located here…

…is confusing because it offers two combinations:
Pacemaker 1.0 for Corosync 1.x
Pacemaker 1.1 for Corosync 2.x
According to the documentation, if you use Corosync 1.x you need
Pacemaker 1.0, but if you use Corosync 2.x then you need Pacemaker
1.1.
However, on my Centos 6.9 system, when I do ‘yum install pacemaker
corosync” I get the following versions:
pacemaker-1.1.15-5.el6.x86_64
corosync-1.4.7-5.el6.x86_64
What’s the correct answer? Does Pacemaker 1.1.15 work with Corosync
1.4.7? If so, is the documentation at ClusterLabs misleading?

The page actually offers a third option ... "Pacemaker 1.1 for CMAN or Corosync
1.x". That's the configuration used by CentOS 6.
However, that's still a bit misleading; the documentation set for "Pacemaker 1.1 for
Corosync 2.x" is the only one that is updated, and it's mostly independent of the
underlying layer, so you should prefer that set.
I plan to reorganize that page in the coming months, so I'll try to make it
clearer.
