files stored on PV persistent storage by pod application are not visible on host machine. Configuration shows no errors. Config - single pv, pvc, pod. I am quite new to this environment.

So I have no idea why aaa is not visible on the host machine in google cloud - as I think 'aaa' file should be here.
I think the issue is caused by on what host you examine the directory contents.
