Bug 1428249

the inventory file used for logging upgrade to 3.5.0

Xia,

Can you please provide the entirety of the ansible playbook output? The logic we would need to look at is where we would generate the ES DC template, the portion of logs you pasted is just the 'oc apply' of them.

So, in the old deployer/scripts/upgrade.sh there is this function:

# this is required for the upgrade to ES 2.3.5
function update_es_for_235() {

That adds the downward API NAMESPACE var to ES config

Do we still need that in the new ansible es_migration.sh?

We already provide that as part of the ES dc we generate:
https://github.com/openshift/openshift-ansible/blob/master/roles/openshift_logging/templates/es.j2#L61-L64

The problem it seems like, is that we didn't even generate an ES DC template...

@eric I wonder if we suffer from the same thing that fixed pvc: https://github.com/openshift/openshift-ansible/pull/3548/files#diff-8484225afbf0539375b973fb21b46838R68

No problem, let me redo the upgrade to provide the full log. Just need some more hours for 3.3.1 logging systems to generate log entries on journald log driver system. Will attach it soon later.

full ansible upgrade log

@ewolinet 
The original issue was reproduced and full ansible upgrade log was attached.

Thanks Xia,

I see this in the log:

STDERR:

The DeploymentConfig "logging-es-5a36v5kl" is invalid: 
* spec.template.spec.volumes[2].hostPath: Forbidden: may not specify more than 1 volume type
* spec.template.spec.containers[0].volumeMounts[2].name: Not found: "elasticsearch-storage"


I'll log on and see how the DC was generated

So this looks to be due to the fact that the currently deployed ES DC uses a host mount, however the generated DC template for ES uses an emptyDir.

So when the role tries to apply it clobbers and then it seems that its left without an 'elasticsearch-storage' volume definition.

Current DC snippet:
        volumeMounts:
        - mountPath: /etc/elasticsearch/secret
          name: elasticsearch
          readOnly: true
        - mountPath: /usr/share/elasticsearch/config
          name: elasticsearch-config
          readOnly: true
        - mountPath: /elasticsearch/persistent
          name: elasticsearch-storage
      volumes:
      - name: elasticsearch
        secret:
          defaultMode: 420
          secretName: logging-elasticsearch
      - configMap:
          defaultMode: 420
          name: logging-elasticsearch
        name: elasticsearch-config
      - hostPath:
          path: /usr/local/es-storage
        name: elasticsearch-storage

Template snippet:
          volumeMounts:
            - name: elasticsearch
              mountPath: /etc/elasticsearch/secret
              readOnly: true
            - name: elasticsearch-config
              mountPath: /usr/share/java/elasticsearch/config
              readOnly: true
            - name: elasticsearch-storage
              mountPath: /elasticsearch/persistent
      volumes:
        - name: elasticsearch
          secret:
            secretName: logging-elasticsearch
        - name: elasticsearch-config
          configMap:
            name: logging-elasticsearch
        - name: elasticsearch-storage
          emptyDir: {}
