Description Miroslav Lisik 2019-03-11 18:13:24 UTC 
Created attachment 1542983 [details]
pcsd_virt-151.log

Description of problem:
Cannot create cluster with pcs GUI.

Version-Release number of selected component (if applicable):
pcs-0.10.1-4.el8

How reproducible:
always

Steps to Reproduce:
1. setup password for hacluster user on the host for cluster nodes
# echo password | passwd hacluster --stdin

2. Enable and start pcsd daemon
# systemctl enable pcsd
# systemctl start pcsd


3. Go to pcs GUI address: https:/<hostname>:2224/
e.g.

https://virt-151.cluster-qe.lab.eng.brq.redhat.com:2224/

4. Log in as hacluster using your password

5. On manage page click on "Create New"

6. "Create cluster" dialog pops up and fill the "Cluster name", "Node 1" and Node2" fields.
e.g.

Cluster Name: TestCluster
Node1: virt-151.cluster-qe.lab.eng.brq.redhat.com
Node2: virt-152.cluster-qe.lab.eng.brq.redhat.com

7. Click on "Create cluster" button and "Authentification of nodes" dialog pops up.

8. Check checkbox "Use same password for all nodes" and fill the password.

9. Click on "Authenticate" button.

10. "Authentication of nodes" dialog disappears and "Create cluster" dialog is still visible but "Create cluster" and "Go to advance settings" buttons are inactive.

11. Check the corosync.conf file on the nodes
# ls /etc/corosync/corosync.conf
ls: cannot access '/etc/corosync/corosync.conf': No such file or directory

Actual results:

Cluster is not created. Corosync file is not even created on the nodes.

Expected results:

Cluster is created.


Additional info:

Pcsd debug logs are attached.

There is error message in browser console:

Comment 2 Tomas Jelinek 2019-03-12 08:56:08 UTC 
Workarounds:

A) create a cluster in GUI
* in step 7, click "Go to advance settings" instead of "Create cluster"
* once you go through nodes authentication and get to advanced setup dialog, click "Add link..."
* click "Create cluster", no need to actually fill-in anything in the form

B) create a cluster in CLI
