> # oc adm upgrade --to-image=registry.svc.ci.openshift.org/ocp/release:4.0.0-0.nightly-2019-02-13-204401

I've changed the component from Installer to Upgrade, since the issue is this post-install step.
Comment 2 liujia 2019-03-11 07:39:08 UTC 
Hit the issue again when do upgrade manually from 4.0.0-0.nightly-2019-03-04-234414 to 4.0.0-0.nightly-2019-03-06-074438.

The same steps with those in description.

Comment 5 Johnny Liu 2019-03-13 08:42:28 UTC 
Today I hit the issue too when do upgrade from quay.io/openshift-release-dev/ocp-release:4.0.0-0.7 to registry.svc.ci.openshift.org/ocp/release:4.0.0-0.nightly-2019-03-06-074438.

Steps:
1. install beta2 released cluster as a base cluster

2. change cincinnati server to my dummy build graph.
# oc get clusterversion -o yaml
<--snip-->
  spec:
    channel: stable-4.0
    clusterID: b98615d8-224c-4737-8934-c822e3dcbb58
    upstream: http://3.86.146.114/cincinnati_build_graph
<--snip-->
# curl http://3.86.146.114/cincinnati_build_graph
{
  "nodes": [
    {
      "version": "4.0.0-0.7",
      "payload": "quay.io/openshift-release-dev/ocp-release:4.0.0-0.7",
      "metadata": {"description": "Beta 2"}
    },
    {
      "version": "4.0.0-0.nightly-2019-03-06-074438",
      "payload": "registry.svc.ci.openshift.org/ocp/release:4.0.0-0.nightly-2019-03-06-074438"
    }
  ],
  "edges": [
    [
      0, 
      1
    ]
  ]
}

3. Trigger upgrade
# oc adm upgrade --to=4.0.0-0.nightly-2019-03-06-074438
Updating to 4.0.0-0.nightly-2019-03-06-074438

4. Upgrade is completed.
# oc get clusterversion
NAME      VERSION                             AVAILABLE   PROGRESSING   SINCE   STATUS
version   4.0.0-0.nightly-2019-03-06-074438   True        False         6m58s   Cluster version is 4.0.0-0.nightly-2019-03-06-074438

5. After 12 hours later, check cluster again.
# oc get clusterversion

Comment 6 Wenjing Zheng 2019-03-13 09:05:42 UTC 
I hit issue from 4.0.0-0.nightly-2019-03-04-234414 to 4.0.0-0.nightly-2019-03-05-045224.
Comment 7 Wei Sun 2019-03-13 09:15:03 UTC 
Add testblocker keyword,since once we hit this issue,then the upgrade testing could not be moved forward.
Comment 8 Johnny Liu 2019-03-13 16:40:37 UTC 
Maybe this bug is some side effect introduced by https://bugzilla.redhat.com/show_bug.cgi?id=1688321, even before upgrade, base cluster probably already would get into `Degraded` state (have to wait for some time).

That sounds plausible to me.  Try with a RHCOS newer than 47.330 (see [1])?

Comment 10 Colin Walters 2019-03-14 18:23:34 UTC 
Yes, we need to update RHCOS.  Also I think it should be fairly easy to do a quick sanity check for this by mirroring the release payload to any registry that requires auth and injecting the auth required into the pull secret.
Comment 11 Johnny Liu 2019-03-15 05:47:23 UTC 
And yesterday I used 400.7.20190306.0 as AMI for based cluster, then upgrade the cluster, did not reproduce such issue any more.

According to https://bugzilla.redhat.com/show_bug.cgi?id=1688321#c6, we would not support beta2 to beta3 upgrade, so this issue is out of our test plan. So I am okay with close it as 'WONTFIX'.
Comment 12 zhou ying 2019-03-25 07:17:11 UTC 
Today I hit the same issue when do upgrade from 4.0.0-0.nightly-2019-03-22-191219 to registry.svc.ci.openshift.org/ocp/release:4.0.0-0.nightly-2019-03-23-183709:


Steps:
1. install ocp env from Payload: registry.svc.ci.openshift.org/ocp/release:4.0.0-0.nightly-2019-03-22-191219,  as a base cluster

2. change cincinnati server to OCP graph.

3. Trigger upgrade

Comment 14 zhou ying 2019-03-25 09:56:33 UTC 
On today's test, we have met this frequently. So reopening it.
Comment 15 Colin Walters 2019-03-25 12:50:52 UTC 
Whenever you see Degraded systems, look at the MCD logs:

`oc -n openshift-machine-config-operator logs pods/machine-config-daemon-xyzxyz`

Can you get some output from that?
Comment 16 Antonio Murdaca 2019-03-25 12:57:05 UTC 
also, we've change the way that check (syncRequiredMachineConfigPool) works and it now instantly reports if it's not finished flipping to failing. So, my question is, does it eventually flip back to Failing: False if you leave the upgrade process running for some more time?

Maybe we shouldn't set Failing if we error on that but keeps retrying.
Comment 17 Antonio Murdaca 2019-03-25 17:39:29 UTC 
It would also be nice if you provide informations by just using https://github.com/openshift/must-gather which auto-collects the data we need to debug.

Comment 29 Wei Sun 2019-03-26 09:04:50 UTC 
From this Monday,we frequent meet this bug,current QE's upgrade test is blocked by this bug.
Comment 30 Antonio Murdaca 2019-03-26 10:03:17 UTC 
>  Booting the MCD errored with can't reconcile config rendered-master-8c108b7752cb2545da64b96e15241d8c with rendered-master-13131f3a8f1d80a10d2149723b4bed3f: ignition links section contains changes: unreconcilable


That error is pretty clear though, it looks like between those machineconfigs, the links section has been altered and we can't reconcile.

I'll try to understand what is touching the links section though...I can't connect to the cluster with your kubeconfig, it times out.
Comment 31 Antonio Murdaca 2019-03-26 10:07:07 UTC 
Ok, the links section being added is the stopgap we introduced to support pulling the pause image when it's authenticated (ref: https://github.com/openshift/machine-config-operator/pull/535)

the new MachineConfig contains:

```
      links:
      - filesystem: root
        overwrite: false
        path: /root/.docker/config.json
        target: /var/lib/kubelet/config.json
```

and that's causing the issue.
Comment 33 Antonio Murdaca 2019-03-26 10:17:10 UTC 
This has been fixed by https://github.com/openshift/machine-config-operator/pull/540 which reverted https://github.com/openshift/machine-config-operator/pull/535 which was adding a symlink which isn't supported for reconcile.

What's happening now is that:

1) you're starting a cluster with an MCO version which contains #535
2) you're upgrading to a payload which doesn't have #535 but have #540

The above means that 1) generates MachineConfigs with an unsupported symlink and when upgrading to 2), the symlink is removed causing drift and an unreconcilable error.


> I also hit the same issue from 4.0.0-0.nightly-2019-03-23-222829 to 4.0.0-0.nightly-2019-03-25-154140 upgrade.

This BZ should be fixed as long as you use a starting cluster from a payload that contains #540
Comment 34 Antonio Murdaca 2019-03-26 10:24:27 UTC 
This PR that I've just made is also helping with transitioning this test scenarios from old payload that don't contain #540 https://github.com/openshift/machine-config-operator/pull/580

But I'd consider the BZ fixed as long as you use a newer payload.
Comment 36 liujia 2019-03-27 06:01:58 UTC 
Based comment33, QE use a source node including #540 and have a test against latest avialble upgrade path(from 4.0.0-0.nightly-2019-03-25-180911 to 4.0.0-0.nightly-2019-03-26-072833).
Upgrade succeed.

So remove the blocker keywords.

For the comment34, since pr580 is still not avaialble in any green path.
So, keep the bug ON_QA status, will verify it after a new support upgrade path including the build ready for test.
Comment 37 liujia 2019-04-04 02:52:51 UTC 
Continue the comment36, since there is not an avaliable update path in the last week(with a start node not including #540, a end node including #580). Currently, all nightly build not including #540 have been removed from [1]. And as for a beta3 release build, which will include #540. So according to the verify in comment36. Verify the bug and change status.

https://prow.svc.ci.openshift.org/view/gcs/origin-ci-test/logs/release-openshift-origin-installer-e2e-aws-upgrade/7374#0:build-log.txt%3A2493

I saw a similar error msg in the CI:
Sep 20 11:35:35.264 E clusteroperator/machine-config changed Degraded to True: RequiredPoolsFailed: Failed to resync 4.2.0-0.nightly-2019-09-20-102942 because: timed out waiting for the condition during syncRequiredMachineConfigPools: error pool master is not ready, retrying. Status: (pool degraded: false total: 3, ready 0, updated: 0, unavailable: 1)

Not sure if it is from the same cause. Reopening ... Please close if it is not.
Comment 41 Antonio Murdaca 2019-09-20 14:14:29 UTC 
from logs on one of the master:

```
I0920 11:26:35.411199    5381 update.go:89] pod "packageserver-6cc7c655f4-k97r4" removed (evicted)
I0920 11:36:28.680522    5381 update.go:89] pod "downloads-64f8dbd46c-xdgzs" removed (evicted)
```

The timeout to the upgrade is caused by the download pod not evicting and taking ~600s (10m) to stop. That causes a delay which is reflected to upgrade time/roll out time.

The bug to track is: https://bugzilla.redhat.com/show_bug.cgi?id=1745772
Comment 42 liujia 2019-09-23 02:35:02 UTC 
Please file a new bug when regression found if previous one is closed. 
So restore the bug's initial status back.
