[ClusterLabs] Maximum number of supported cluster nodes differ in different sections of clusterlab.org documentation

[Michael Reichert]

Hi,

I would have a question regarding the maximum number of cluster nodes supported by Corosync 3.x and Pacemaker 2.1.

On the https://clusterlabs.org<https://clusterlabs.org/>  entry page one can find the following statement:

„We support many deployment scenarios, from the simplest 2-node standby cluster to a 32-node active/active configuration.“

But in the  “Scaling a Pacemaker Cluster” chapter - https://clusterlabs.org/pacemaker/doc/2.1/Pacemaker_Remote/html/intro.html - one can find this contrary statement:

„In a basic Pacemaker high-availability cluster [1]<https://clusterlabs.org/pacemaker/doc/2.1/Pacemaker_Remote/html/intro.html#id2> each node runs the full cluster stack of Corosync and all Pacemaker components. This allows great flexibility but limits scalability to around 16 nodes.“

Is this just a documentation inconsistency from a previous release?

Btw, current Linux distros like Redhat or SUSE both mention a 32 node upper limit, too:

https://documentation.suse.com/sle-ha/15-SP1/html/SLE-HA-all/cha-ha-concepts.html

Thanks in advance!

Regards,
Michael
