Ocfs2 users - Aug 2017 - Cluster name is invalid while trying to join the group

Hello list,

We are using debian wheezy based 3 node OCFS2 cluster:

ii  ocfs2-tools                           1.6.4-1+deb7u1                 
     amd64        tools for managing OCFS2 cluster filesystems

4.1.1 custom kernel on all 3 nodes. Since we had performance issues with 
it we have decide to upgrade from wheezy -> stratch.

This was not truely an upgrade, rather installing a new brand new 
stratch node and move over the main configs.

ii  ocfs2-tools                      1.8.4-4                        
amd64        tools for managing OCFS2 cluster filesystems

The cluster.conf on all 3 machines:

cluster:
	node_count = 3
	name = web

node:
	number = 0
	cluster = web
	ip_port = 7777
	ip_address = 10.0.0.2
	name = webserver1

node:
	number = 1
	cluster = web
	ip_port = 7777
	ip_address = 10.0.0.3
	name = webserver2

node:
	number = 2
	cluster = web
	ip_port = 7777
	ip_address = 10.0.0.4
	name = webserver3

The new node fails to join the cluster with:

We have tried everything, including shutting down 1 of the 3 nodes to 
the point of shutting down all nodes except the new one. It still cannot 
start start.
We have also migrated the old 4.1.1 kernel with the exact same modules 
to the new webserver3, it did not help either.

Any ideas what is causing this?
