Describe the bug

Plex Media Server cannot scan files stored in another SSD which already has been successfully Merged into CasaOS HD. Either do the SSH ls command without the using sudo.

To Reproduce

Steps to reproduce the behavior:

1. original SSD running CasaOS being full
2. insert another SSD via USB, automatically mounted
3. Merge the storages into a combined “CasaOS HD” and it’s working.
4. In File explorer, manually upload a test file as /DATA/Media/Misc/TestVideo.mkv, which is successful.
5. the physical location can also be viewed in /media/devmon/Media3/Media/Misc/TestVideo.mkv
6. try SSH ls the Test.Video.mkv of the devmon directory, access denied
7. try SSH ls the video of the /Data directory, it doesn’t appear.
8. try Scan the /DATA/Media/Misc directory in Plex, the TestVideo doesn’t appear.
9. try SSH sudo ls the video of above 2 directories, it appears.

Expected behavior

It should appear as expected using non-sudo SSH or in Plex.
