I researched a lot of sites and make a few mistakes but the great thing about the Pi is that you can just reload the OS and start over. I believe I got most of the process from this YouTube video https://youtu.be/0U7NATfeTxg and there’s links to the commands and content from that page. I needed to research mounting the Drobo Share separately as most of these examples explain how to mount an external drive, not a NAS share. You’ll also want to search for LetsEncrypt and CertBot if you’re planning on using SSL (I highly recommend it). You can get a free SSL certificate from Lets Encrypt and then CertBot will auto-renew it for you so that your free cert stays valid.
As for mounting the share, here’s the entry I made to the fstab file for my system:
//192.168.xx.xx/nextcloud /mnt/nextcloud cifs credentials=/home/pi/.NCCREDS,file_mode=0770,dir_mode=0770,uid=33,gid=33
I had been trying to install NextCloud (which is why my mountpoints say “nextcloud”), but you can name it whatever you want. You’ll need to update the IP address to whatever address your Pi is configured as. Hopefully this will help.
