ha-cluster-join bootstrap script error "cluster.join: not enough values to unpack (expected 3, got 1)"

SUSE Linux Enterprise High Availability Extension 15 SP2


The first cluster node (e.g. "node1" with IP address is setup successfully using the "ha-cluster-init" bootstrap script.

But adding the second cluster node (e.g. "node2" with IP address using the "ha-cluster-join" bootstrap script encounter errors.
For example:
  node2:~ # ha-cluster-join -c
  ERROR: cluster.join: not enough values to unpack (expected 3, got 1)


1. Remove the node information for "node2" from "/etc/corosync/corosync.conf" inside "node1".

   For example, before change:
     node {
       nodeid: 1
     node {
       nodeid: 2

   After change:
     node {
       nodeid: 1

2. Sync the changes to "node2" by running "csync2" command in "node1":
     node1:~ # csync2 -xv

3. Restart "corosync.service" in "node1":
     node1:~ # systemctl restart corosync.service

4. Run the "ha-cluster-join" bootstrap script in "node2":
     node2:~ # ha-cluster-join -c

5. "node2" should be able to join "node1" in the cluster now.


After repeated failed attempts to setup the cluster nodes, the "/etc/corosync/corosync.conf" configuration is no longer in a clean state.
The node information for the second node must be cleaned up from the "/etc/corosync/corosync.conf" before running "ha-cluster-join" bootstrap script again.
