I have Volumio installed on a RPI4 using the AudioPhonics streamer. Everything works great, except the USB drive is throwing me for a loop.
I have an external RAID1 USB drive plugged into the PI, I can see it when I ssh in. I formatted it as EXT4 and it shows up as /dev/sda1.
I then connected to the pi from a Mac from Finder using Connect to remote server… smb://192.168.x.x./usb. I copied some files over to it successfully from Finder. The files show up on Volumio under Music Library → USB. I can see the files I copied and play them on Volumio. Great success!
My concern is when I unplug the USB drive, the files still show up in Volumio and I can still play them. I unplugged the USB drive, rebooted everything and the files are still there and playable.
Hence, I assume the files are not actually going on to the USB drive, but the microSD card. How can I correct this?
