You should mount the share somewhere in /home/user/MyDocs/some-folder.

Warning: when canola scans the database, which it will do whenever you power the device on or off or insert a memory card so something of that sort, it will take about 30 min. i have my 770 mount an external usb drive, it takes forever to scan it (if anyone knows a way to make it faster plz let me know.)

If you want more info look here:

And you will also go into the web interface for configuring canola and tell it to look in /home/user/MyDocs/some-folder.
