I just reinstalled osmc on my pi3 because the samba service got broken due to my tinkering with it. However, I notice that there is only one default share now, a folder called “osmc”.
On the previous installation, my two USB disks got shared automatically. I know this because I recently addede another disk, and I did no configuration at all, but it popped up as a windows share still.
So, how can I either make the server share all USB disks automatically, or share them manually once and for all? Do I have to do it manually in the smb.conf file? If so, how come it happened automatically in the previous installation?
Have you rebooted the pi since you installed the smb server? The automounter (which I believe is also responsible for interfacing with the OSMC SMB app only runs once per boot or once each time a drive is attached. It will only pick up drives added before the app was installed after they are either plugged in again or the pi is restarted.
