Official FAQ on using calibre with a NAS:
http://manual.calibre-ebook.com/faq.html#i-am-getting-errors-with-my-calibre-library-on-a-networked-drive-nas

tl;dr -- don't.
calibre has never supported networked libraries, and although some people
have gotten it working, there is no particular reason -- it seems to work
sometimes, and sometimes not. Often people come to the support forums
complaining that what once worked, stopped working "for no reason
whatsoever".

Your situation is not even slightly uncommon. My usual recommendation is,
if it is really important to have a networked copy, use rsync to mirror
your calibre library on your networked filesystem.

That being said, you can always try. :)
One thread that discusses the issue:
http://www.mobileread.com/forums/showthread.php?t=218463
Problems include inconsistent support for file locking and hardlinks (file
operations are atomic).

Perhaps you will hit upon the magic combination.
