Hi!
I'm a novice in using self-node-remediation. I'm currently testing this operator in a cluster, and noticed the following issue. I've added the RegistryIsNotAvailable condition to the NodeHealthCheck CRD for testing. When this condition arises in a node, it successfully reboots. However, if this condition continues to persist on the node after the reboot, the taints are removed and shortly after, the node is sent to reboot again.
Could you please advise on the expected behavior of self-node-remediation in a case where a reboot does not resolve the issue?
Thanks,
Stanislav.

Hi Stanislav,
Thanks for reaching out.
In general this is an unexpected behavior, taints are to be removed only when the node becomes healthy again.
My best guess is that this is caused by the node shortly becoming healthy.
Can you please add NHC / SNR logs, so we may investigate further ?

Hello, Michael!
Thanks for the fast response.
I have already run tests on several clusters. Here are my logs from the following actions:
• NHC and SNR are monitoring three working nodes where the Node Problem Detector is running (docker image from a private repository: node-problem-detector:v1)
• I put tag v1 on the docker image with NPD build where the RegistryIsNotAvailable check is broken
• I restart NPD on one node, as a result of which node has a RegistryIsNotAvailable condition
• After 120s selfnoderemediations.self-node-remediation.medik8s.io is created for this node
• The node reboots (I intentionnaly gave SNR wrong path to watchdog as far as we have bug in watchdog driver, but software reboot works as expected)
• After rebooting, NPD with a broken RegistryIsNotAvailable check starts on the node
• Despite this, taints are removed from it, and selfnoderemediations.self-node-remediation.medik8s.io is created again
• While the node is rebooting, I tag v1 on the docker image with the normal NPD build
• Taints are removed from the node and, since this time it doesn't have the RegistryIsNotAvailable condition, it continues to work
Maybe I'm doing the test wrongly, but it currently looks like SNR ignores the condition after rebooting and removes taints in any case, which leads to a reboot cycle.

Thanks for the fast response.
I have already run tests on several clusters. Here are my logs from the following actions:
• NHC and SNR are monitoring three working nodes where the Node Problem Detector is running (docker image from a private repository: node-problem-detector:v1)
• I put tag v1 on the docker image with NPD build where the RegistryIsNotAvailable check is broken
• I restart NPD on one node, as a result of which node has a RegistryIsNotAvailable condition
• After 120s selfnoderemediations.self-node-remediation.medik8s.io is created for this node
• The node reboots (I intentionnaly gave SNR wrong path to watchdog as far as we have bug in watchdog driver, but software reboot works as expected)
• After rebooting, NPD with a broken RegistryIsNotAvailable check starts on the node
• Despite this, taints are removed from it, and selfnoderemediations.self-node-remediation.medik8s.io is created again
• While the node is rebooting, I tag v1 on the docker image with the normal NPD build
• Taints are removed from the node and, since this time it doesn't have the RegistryIsNotAvailable condition, it continues to work
Maybe I'm doing the test wrongly, but it currently looks like SNR ignores the condition after rebooting and removes taints in any case, which leads to a reboot cycle.

Hi,
not sure if I fully understand this:
> • After rebooting, NPD with a broken RegistryIsNotAvailable check starts on the node
> • Despite this, taints are removed from it, and selfnoderemediations.self-node-remediation.medik8s.io is created again
> • While the node is rebooting, I tag v1 on the docker image with the normal NPD build
> • Taints are removed from the node and, since this time it doesn't have the RegistryIsNotAvailable condition, it continues to work
>
> Maybe I'm doing the test wrongly, but it currently looks like SNR ignores the condition after rebooting and removes taints in any case, which leads to a reboot cycle.

What happens when the node reboots, what is the status of the RegistryIsNotAvailable condition?
Having a quick look at the NHC logs, I assume there is a period of time when no unhealthy condition is matching (so Ready = True, and RegistryIsNotAvailable = False or Unknown, or isn't set). Then NHC deletes the SNR CR, and that triggers taint removal.

Only after that RegistryIsNotAvailable is True again for 2 minutes, and a new remediation starts.
Does that make sense?
Just for clarification: SNR isn't watching conditions itself, it reacts to CR creation / deletion (and API server connectivity, but that's not relevant in this case)

Hi, Marc!
Yes, I also assumed that at some point condition RegistryIsNotAvailable = True or Unknown, but I couldn't find any signs of this. It is possible that NodeProblemDetector changes the condition status at startup after a reboot. However, usually all changes in conditions are reflected in the node's events list, and it's not there.
Besides, I'm interested in the logic of the operators working after a node reboot. What is required for a node to be marked as healthy after a reboot? Is a few seconds of condition = False sufficient for the taint to be removed?
Perhaps, I'll try to set the Unknown status for NHC as a sign of an unhealthy node. Let's see how it behaves in this case.
Thanks!
Stanislav

Fair point, but there are multiple "RegistryIsNotAvailable is now: True" events, so I guess the condition wasn't True or didn't exist in between? The LastTransitionTime on the condition might be useful as well.

- every change of node conditions triggers NHC. The reason for the change (e.g. kube's controller manager reacts to node availability during / after reboots and updates the Ready condition, or NPD is updating its conditions when it stopped or started?) doesn't matter.
- when no node condition matches any of the configured unhealthy conditions for the configured duration, the node is considered healthy. For the duration, the condition's LastTransitionTime is relevant. (*)
- for healthy nodes, NHC deletes SNR CR
- CR deletion triggers SNR, which removes taints.
(*) the upcoming release will have a change here, which *might* be relevant (https://github.com/medik8s/node-healthcheck-operator/pull/274):
A node will NOT be considered healthy, when it's unhealthy already, and a node condition matches any of the configured unhealthy conditions NO MATTER if the configured duration expired already.
A possible scenario *might* be:
- RegistryIsNotAvailable is True -> node becomes unhealthy after 2 minutes
- node is rebooted, Ready condition is set to False
- RegistryIsNotAvailable is either removed, or set to Unknown or False for whatever reason -> node still unhealthy because of Ready condition
- NPD is started and sets RegistryIsNotAvailable to True -> 2 minute "countdown" starts, node still unhealthy because of Ready condition
- boot completed, Ready condition = True
-> current NHC version: node is healthy, because 2 minutes didn't expire yet; when they do, node is unhealthy again
-> next NHC version: because the node was unhealthy, and there is a "running countdown" already, node is NOT considered healthy
In case you want to give the new version a try, I just pushed "v0.7.0-rc2" tags of operator and bundle images to Quay.
Thanks!
Stanislav

Hello, Marc!
I dug deeper into how NPD assigns statuses and found out that upon initialization it initializes all conditions to False. According to the documentation, this functionality can be disabled by adding skip_initial_status=true to the configuration of a custom check.
BTW, I ran some tests and found that this feature doesn't work as expected: conditions with skip_initial_status are not updated at all. The reason might be a bug made by the developer who added this feature. In the code, you can see that he completely disabled the initialization of conditions for checks with skip_initial_status. This probably leads to the check not being able to update later. However, this should not affect the removal of the NHC taint. I verified that starting NPD with skip_initial_status=true actually does not initialize RegistryIsNotAvailable=False.
I conducted an experiment by adding to the NodeHealthCheck:
duration: 30s
status: Unknown
type: RegistryIsNotAvailable
I don’t yet understand why, but after that, the taint from the node is no longer removed by NHC after reboot. I will continue to investigate this.
I also plan to test v0.7.0-rc2. Thank you for this opportunity! I will report back on Monday or Tuesday.
Have a great weekend!

Hi Marc!
As promised, I'm back with the results. I've tested the v0.7.0-rc2 version under the same conditions. That is, NPD sets RegistryIsNotAvailable=True, and the node reboots within 2 minutes. After the reboot, NPD (if I'm correct) resets RegistryIsNotAvailable=False and then sets it to True again after running the corresponding check. The behavior of NHC v0.7.0-rc2 is the same - it removes the taint shortly after the node comes back from reboot, and reassigns it after 2 minutes.
For now, I will focus on fixing the bug in Node Problem Detector so it's possible to disable condition reset at startup and update them later.
Best regards,
Stanislav.

Thanks for the update!
Yes, when RegistryIsNotAvailable=False (and Ready=True already I assume), the rc2 version doesn't change anything.
The NPD skip_initial_status sounds promising though!
The NPD skip_initial_status sounds promising though!
If that also doesn't help, we need to evaluate options for NHC. There is a long standing idea for introducing something like a "nodeBootTime" option, during which conditions aren't evaluated. So far we didn't really need it though.
Cheers,
Marc

Hello, Marc!
The reboot cycle problem has been resolved with the combination of v0.7.0-rc2 and a patched NPD. Now, if the problem persists after reboot, the node remains cordoned.
I made a PR with a bug fix in NPD, it is waiting for testing by maintainers.
Thanks for your help!
