The path does not exist or lacks permission.
All TiKV nodes must have the corresponding directory and ensure the permissions are correct, with write permission.

Does the TiKV node need to have a shared directory? I placed the shared directory on the PD server. So, it’s reporting that it can’t find the file and path, right?

All TiKV nodes need to be able to access this directory.
