Not Linux, but the ever confounding OSX (mac mini) with library on a Drobo 5N, connected via ethernet.
I’m one of the people who has from the beginning (well, coming up on end of my 12th month), and continuing through build 200, had disappearing libraries. I had hoped this was fixed for me in 1.3, but it is not. Fortunately, the new backup approach has meant that the four or five times I have seen my tracks dwindle rapidly, I could restore from a backup…still, is this a good thing?
(There is much to like about 1.3…many of my wishlist items are there and work beautifully. But the dwindling library, combined with this ever-scanning, ever-spinning thing, is a killer.)
Library is about 281,000 tracks.
