Cannot delete files inside K8s container within mounted Azure File Share - linux

Question

I have a problem when deleting files inside container.
Here is the command I execute via kubectl:
kubectl exec mypod-7ddbbb6c87-cwl76 -- ls -lat /usr/bin/myprogram/logs
-rwxrwxrwx 1 1000 1000 186446 Oct 22 12:59 mylogfile.log
kubectl exec mypod-7ddbbb6c87-cwl76 -- find /usr/bin/myprogram/logs -type f -mtime +14 -delete
find: cannot delete '/usr/bin/myprogram/logs/mylogfile.log': No such file or directory
I cannot understand what is the problem?
This directory /usr/bin/myprogram/logs is volume mount of Azure File Share.
This AzureFileShare is used for multiple deployments\pods therefore PV is ReadWriteMany
Here the part of my Yaml configuration
kind: StorageClass
apiVersion: storage.k8s.io/v1

name: mypod-logs
provisioner: kubernetes.io/azure-file

Answer 1

All the things work fine on my side as the screenshot below shows:
But I met the same issue before. You can try to execute the command like this:
kubectl exec mypod-7ddbbb6c87-cwl76 -- bash -c "find /usr/bin/myprogram/logs -type f -mtime +14 -delete"
