Partial NFS Volume Mount Failures Following OpenShift 4.14 Upgrade (error: code = FailedPrecondition desc = open /var/lib/trident/tracking/pvc-xx-xx-xx-xx-xx.json: no such file or directory) #891

Describe the bug I have encountered an issue after upgrading from OpenShift 4.12.x to OpenShift 4.14.x. Following the upgrade, as the updated nodes were brought back online, I noticed that certain NFS volumes were unable to be mounted, resulting in the corresponding application pods remaining in a "Pending" state. Below, I have attached the log from a Linux-Trident DaemonSet pod which seems to indicate that it is looking for a status/tracking file in "/var/lib/trident/tracking/" for the PVC to be mounted, but is unable to find it. This issue only affects some PVCs (5-10% of all PVCs). - Other PVCs from the same backend storage were mounted without any issues.

As a workaround, I manually copied the missing JSON tracking file from another remaining CoreOS node and deleted the "publishedTargetPaths" value. This temporarily allowed Trident to remount the volume.

Steps to temporarily fix it: find and copy the tracking file from a remaining worker node /var/lib/trident/tracking/pvc-xxx.json

{"localhost":true,"fstype":"nfs","useCHAP":false,"nfsServerIp":"x.x.x.2","nfsPath":"/trident_qtree_pool_mypool/pvc_xxxx","mountOptions":"nfsvers=4","VolumeTrackingInfoPath":"","stagingTargetPath":"/var/lib/kubelet/plugins/kubernetes.io/csi/csi.trident.netapp.io/6734d5d5887c0af8b6f03b9d5a6bf4ff633330fe61d2af0be3380023662eadd4/globalmount","publishedTargetPaths":{"/var/lib/kubelet/pods/359a2c7b-d230-4b8c-b92e-ef4e64c806a0/volumes/kubernetes.io~csi/pvc-c37c2a27-9c57-4a3a-8380-b561ccfd7a4d/mount":{}}}

remove the value from publishedTargetPaths and let the corresponding linux trident pod reconcile its value.

{"localhost":true,"fstype":"nfs","useCHAP":false,"nfsServerIp":"x.x.x.2","nfsPath":"/trident_qtree_pool_mypool/pvc_xxxx","mountOptions":"nfsvers=4","VolumeTrackingInfoPath":"","stagingTargetPath":"/var/lib/kubelet/plugins/kubernetes.io/csi/csi.trident.netapp.io/6734d5d5887c0af8b6f03b9d5a6bf4ff633330fe61d2af0be3380023662eadd4/globalmount","publishedTargetPaths":{}}

I also tried to delete the Operator/Controller and DaemonSet before manually creating the file, hoping this would resolve the issue. Unfortunately, this did not work.

Here is the log from the Trident DaemonSet pod:

Environment Provide accurate information about the environment to help us reproduce the issue.

We have been using Trident for 3-4 years now and have never encountered this error before.

-- EDIT -- We also face the same issue with Trident Version 24.02.0.

Xavier-0965 commented 2 months ago

We had the same issue also after updating from Openshift 4.13.34 to 4.14.19. Trident version: 24.02.0 Kernel: 5.14.0-284.52.1.el9_2.x86_64 Container runtime: cri-o: 1.27.4-6.1.rhaos4.14.gitd09e4c0.el9 Kubernetes version: v1.27.11+749fe1d

Kubernetes orchestrator: OpenShift 4.14.19 OS: CoreOS/RedHat 9.2

One pod was in ContainerCreating state. The events was 

  Warning  FailedMount  54s (x8 over 15m)   kubelet            MountVolume.SetUp failed for volume "pvc-c476790e-1b18-4080-967d-99af41b1122a" : rpc error: code = FailedPrecondition desc = open /var/lib/trident/tracking/pvc-c476790e-1b18-4080-967d-99af41b1122a.json: no such file or directory

After I have restarted the pod of the daemonSet trident-node-linux, that was running on the same node as the failing pod, the error message was still in the log. But after I have restarted the failing pod, the problem has been solved. The json file has been recreated automatically.

Hey @phhutter and @Xavier-0965, I'm looking into this bug. If possible can you upload logs of both controller and node pod with log-level set to debug and also any steps to reproduce this?

To set log-level to debug you can use the following command: tridentctl update logconfig --log-level debug -n trident Or set it to trace: tridentctl update logconfig --log-level trace -n trident

Thanks!

Hey @shashank-netapp

I've fixed all affected PVCs by using the workaround mentioned in my initial comment, which makes it now nearly impossible to gather the requested debug logs. I did this because NetApp support told me that you already have a solution for it and that the fix will be delivered in the next release. ;-) Of course, I was puzzled because whenever I asked about the root cause, no answer was ever given. I will probably stick to GitHub issues only in the future and rely on GitHub issues instead of NetApp support cases.

Unfortunately, it doesn't seem reproducible to me. I've noticed the same issue on 4 clusters out of 30.

What surprises me is that for @Xavier-0965, a restart of the DS supposedly solved the issue. I also tried this when the problem occurred. I restarted the controller, operator, and DaemonSet without any luck. So, it could also be that the problem mentoned by Xavier is unrelated.

Cheers

Hi @shashank-netapp, I had only one persistentVolume with that problem.

As the problem does not occures anymore, I do not have any actual logs. But at the time of the problem, I had the following events for the pod using the PV (oc describe pod POD): (for corporate reason, I have changed the namespace, pod and nodename with the corresponding text (NAMESPACE, e.g.)

Then I have first, delete the pod, to see if the problem is solved. It was not the case. Here the (same) events:

Here a part of the log of trident-node-linux-kcm6s: (At 16. april 2024 around 2:00 UTC, Openshift has been upgraded)

Then I have deleted the pod trident-node-linux-kcm6s, to restart the pod.

But the error message "no such file or directory" was still there.

After I have restartet the pod $pod (that was consuming the persistent Volume), it worked. The PV was successfully mounted.
