SubPath is Used (Not Empty)It looks like it will overwrite the old stuff, which I don't think is perfect

the same SubPath is used more than once, it will be overwritten.
causing confusion in the collection results

    the same SubPath is used more than once, it will be overwritten.

    1.Create a MG CR with PVC

    2.Get the log in pvc and create a new file in it

4, re-create a MG CR with same subpath to check the log in pvc

get the log ，The system reused an existing path, which also included my own file keenon.log, and uploaded it to SFTP, causing log confusion.
