I have a BIG correction. If you follow the instructions titled, "Pacemaker 1.1 for Corosync 2.x," and NOT the ones entitled, "Pacemaker 1.1 for CMAN or Corosync 1.x," guess what? It installs cman anyway, and you spend a couple of days wondering why none of your changes to corosync.conf seem to be working.

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. > > -- > Eric Robinson > > -----Original Message----- > From: Ken Gaillot [mailto:kgail...@redhat.com] > Sent: Tuesday, August 22, 2017 2:08 PM > To: Cluster Labs - All topics related to open-source clustering > welcomed <users@clusterlabs.org> > Subject: Re: [ClusterLabs] ClusterLabs.Org Documentation Problem? > > On Tue, 2017-08-22 at 19:40 +0000, Eric Robinson wrote: >> The documentation located here… >> >> >> >> http://clusterlabs.org/doc/ >> >> >> >> …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?
