So, I recently moved my root folders to another sever and just like some other users I seem to be having an issue getting my network mounted storage to be writable by sonarr.
Radarr was giving me the same issue but after amending the user and group permissions to dietpi:dietpi this made it start working.
I thought, great, Sonarr should work now. But alas this was not the case and i’m getting the annoying “Folder is not writable by user Sonarr” error message when trying to update the root folder in the series editor for all existing series.
Just to reiterate, network mounted storage is writable by radarr but not sonarr.
