Install public samba share but size is only 5GB

Hi,
Before Umbrel I had setup an Ubuntu server for various applications until I game across Umbrel. Fantastic how it is setup! You click on an app, and it will be installed and works!
But I have q question: I want one folder on my Umbrel server (1.3) for music.
I have a Sonos system i want to connect to and I want use Navidrome to play the same music in my iPad/iPhone. I got a public share working after a lot of trying (not a Linux/Debian expert :sweat_smile: pensioner) and is working with the wonderful Sonos app(s2). The problem is that I have a public share that only can contain 5Gb! The other music is uploaded via filebrowser and works fine but Navidrome has no option to connect to Sonos speakers. I don’t want to use airplay. Can somebody put in the right direction and help me?

Server: Intel Nuc 500Gb, 16Gb memory, Intel(R) Core β„’ i3-7100U CPU @ 2.40GHz.
Short version: one (share) folder for Samba and Navidrome.
My apologies if this is in the wrong format but first time a create a request and my English.

Thanks, in advanced.
Hans

Thuis problem is solved I use the standaard downloads folder add music folder and made a samba share.
