After messing up the SD card installation trying to resize the partition I got inspired by someone on this forum setting up a new partition for their library rather than increasing the size of the existing one, but didn’t give instructions I could find …
So I have success following the “Adding a partition” instructions below…
“Don’t forget to also edit this in the main configuration, otherwise it is lost when rebooting the Pi (at least in my case).
Same trick, but then in the file: /var/www/_OS_SETTINGS/etc/samba/smb.conf”
For the Samba config AND the fstab_raspberry file (in _OS_SETTINGS) or your changes will get over written on reboot and you will believe you have gone mad!!
