Relocating /data to USB/SSD and/or boot from USB

Help and Support Help

Hi…

I am quite new to Volumio but just in the phase of setting up a system for me based on Raspberry PI3 and IQAudio DigiAMP+.

Volumio is already working so far. The Pi boots of a 4GB microSD card. As far as I have learned Volumio is storing playlists and all its data in /data.
I also have a 500GB ssd attached via USB. The SSD should contain all music and to avoid aging of the SD card I would like to move as much of the system as possible from the systems sd card to the SSD. At least /data.

Any suggestions on this?
Can I just mount a partition on the SSD to /data? Or is it more recommended to symlink /data to a folder on the SSD?
Will online update still work after this procedure?
How can I move more of the system to the SSD?
As far as I have read Volumio is yet not supporting usb_boot_mode from rpi3. Is this still true?

I don’t want to end up running into a dead end road with the overlay filesystem Volumio is using.

Have others changed their system already in a similar way?

Thanks for your help,

Roland

Volumio uses squashfs and is designed to minimize the number of writes to the sd card. What you are trying to achieve has already been done for you :wink:

Currently native install does not allow to do that; a pending PR might enable it sometime.
In the meantime you may consider a (non-officially supported) option using berryboot bootloader: its gives such flexibility (but has some limitations).
Feel free to consult the relevant guide: you may ask questions to that thread.
