Document URL ============ Red Hat Gluster Storage 3.4: Monitoring Gluster Cluster version from doc-stage Section Number and Name ======================= Chapter 3. Cluster Expansion Section: Running Tendrl-ansible installation for new nodes Describe the issue ================== When customer uses tls based etcd client server authentication, it's necessary to deploy tls certificates on the new machines as well before running the tendrl-ansible as described in given section. When one forgets this, the expand feature won't be available, because WA components on new machines won't be able to talk to WA's etcd instance. See eng BZ 1614874 (NOT A BUG) for details on this scenario. Suggestions for improvement =========================== Add a note or admonition to the chapter "Running Tendrl-ansible installation for new nodes" about the need to deploy tls certificates before running tendrl ansible if one uses tls based client server authentication (ansible variable etcd_tls_client_auth is set to True). Additional information ====================== This was originally suggested to be included in troubleshooting guide, but having this directly in "Cluster Expansion" chapter as a not would be nice as well.
The new admonition looks good.
