No access to files and internal server errors after moving data directory to external harddrive

Nextcloud version (eg, 18.0.2): 20.0.4

Apache or nginx version (eg, Apache 2.4.25): Not sure?
PHP version (eg, 7.1): 7.4.13

The issue you are facing:

No access to files (Error loading img files, Internal Server Error for other files), after moving data directory from local internal storage to local external storage device.

In the mobile android app, the app says that the server is in “maintenance mode” but I can access and view things via the online GUI.

I had some issues with “.ocdata” missing and permissions/ownership, so I think it may be related to that but I can not figure out where to start.

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. Access nextcloud via online GUI or via mobile app

Thanks for your help!

I am on the Nextcloud Snap, and found that mounting the external drive to /media/my/data/ ended up working, after enabling the removable-media plug
