[BUG] permission error on NFS volume

[the-packet-fang]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

While trying to migrate the nc config and data from a local bind to an NFS docker volume, I keep getting the below permission errors.
When connected to the container I can see that all config files are attached to /config.
I added root ALL=(target_user) NOPASSWD: /bin/mkdir to the sudoer, and tried sudo -u abc -c mkdir fromcont and I could see the folder created on the server side.

Expected Behavior

the container should pick the config files and work just like the last state were it was left

Steps To Reproduce

1. upload the conf folder to NFS_server://container_volumes/nc/conf
2. upload the data folder to NFS_server://container_volumes/nc/data
3. chown both folders to 997
4. create two volume for each folder
5. create the container and attach the volumes

Environment

- OS: ubuntu 22
- How docker service was installed: following the official document

CPU architecture

x86-64
