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
