I have a 16G sd card on rapsberry pi2 with volumio 2 installed. I want to install minimserver which needs java to run.
sudo apt-get install default-jdk
Unfortunately the installation process reports no space available and fails
Using ubuntu to view the microSD partitions show boot, volumio and voumio-data totalling approx 16G so it looks that volumio 2 initialised the microSD to use all the space
Running df on the raspberry pi/volumio 2 does not show the volumio-data partition
The question is, why would you want to mess with the existing Volumio installation? Especially since MimiServer is a music-oriented server as well, which is most likely going to conflict with the sole purpose of Volumio: playing music. Volumio is an OS optimised for this one purpose. If you say you’re a Linux noob, I would keep my hands off it.
If your goal is to maintain your library, you can do that externally too. Volumio shares the connected harddrive within the local network, meaning you can manage your library from a laptop or PC. Lot less hassle.
(same trick if your music is stored on a NAS)
