What you expected to happen:

集群有十几个节点，就其中两个节点报错,下面是DaemonSet的yaml `kind: DaemonSet apiVersion: apps/v1 metadata: name: csi-plugin namespace: kube-system uid: 509d3cfc-0dbe-4ebd-8d79-3b8c52774d17 resourceVersion: '601102482' generation: 5 creationTimestamp: '2023-03-21T14:45:10Z' annotations: deprecated.daemonset.template.generation: '5' spec: selector: matchLabels: app: csi-plugin template: metadata: creationTimestamp: null labels: app: csi-plugin annotations: kubectl.kubernetes.io/restartedAt: '2024-06-19T22:22:37+08:00' spec: nodeSelector: kubernetes.io/os: linux restartPolicy: Always serviceAccountName: csi-admin hostPID: true schedulerName: default-scheduler hostNetwork: true affinity: nodeAffinity: requiredDuringSchedulingIgnoredDuringExecution: nodeSelectorTerms:

How to reproduce it (as minimally and precisely as possible):

Anything else we need to know?:

Environment:

• CSI driver version (image tag of csi-plugin container):

• Deployment method (where you got the YAML files, what modifications you made, etc.):

• Kubernetes version (use kubectl version): k8s 1.26

• Cloud provider or hardware configuration (e.g. Alibaba Cloud ECS instance type): 集群节点使用的是阿里云ecs

• OS (e.g: cat /etc/os-release):

• Kernel (e.g. uname -a):

• Network plugin and version (if this is a network-related bug):

• Others:

Why is your filesystem read-only? Is it intentional? What OS are you using?

Why is your filesystem read-only? Is it intentional? What OS are you using?

my cluster is openshift 4.13

the node os is coreos

Comparing logs between normal pods and abnormal pods.

[huww98]

OK, maybe we should never write file into /usr, which is expected to be managed by OS package manager.

You can try set env DISABLE_CSIPLUGIN_CONNECTOR=true. Or upgrade CSI, we have limited the number of retries to 5.

Comparing logs between normal pods and abnormal pods.

I think these logs come from different CSI version.

[lliiang]

hello, does csi-plugin has debug log config? how to open debug log,i want to collect debug log to platform

[huww98]

No. The default log level already outputs almost all the logs.

OK, maybe we should never write file into /usr, which is expected to be managed by OS package manager.

We decided not to fix this one. Because we have planned to remove the connector all together in the future.
