Incomplete mounts table

[rullzer]

@icewind1991 last week you found an issue with the incomplete mount table.

I just upgraded my personal installation to the beta2. And was hit with the same issue (previews breaking, direct links failing). Only on my installation the files_sharing app was still enabled. Disabling and reenabling fixed the issue.

I have been unable to reproduce it since. But this is not good for UX.
Do we need a repair step or something?

That one is still super annoying. Did anyone had any progress here?

Happens on my instance as well, I can access /f/99797 but my wife can not, however she can manually click here way into /apps/files/?dir=/Bilder/Photos/2016/07-30&fileid=99797

But as soon as she refreshes the page there, she is redirected with "file does not exist".

Also on the public link she created you can not use the "download all" button, but you see the file list and everything just fine. I shared the same folder and it works all on my link.
Problem is https://github.com/nextcloud/server/blob/master/apps/files_sharing/lib/Controller/ShareController.php#L564 returns an empty array....

On my instance I couldn't reproduce the issue. All shares continue to work. But as I shared a lot of pictures I noticed this issue:

If the recipient of a folder with images opens the folder he sees the file listing but no previews. What is probably OK because we first need to create them. The user can also download the images. So the share is fine and the user can access the file. If he clicks on the file to view it he gets this message: "Error! Could not generate preview of this file. Please go to the next slide while we remove this image from the slideshow". The folder was shared read-only, maybe this has something to do with the fact that the recipient can't generate the previews for the slideshow?

I can reproduce this behavior. But before I refresh the page I can even download the pictures in the folder. 😕

Yes. That was also broken on c.nc.c by this same bug – see #2297 and #2299

So it looks like the mentioned PR didn't fixed it... Will try now to re-produce this on my dev environment

After ree-enabling sharing everything did as pointed out by @icewind1991 at #2299 (comment) – mind trying that after a DB backup?

But there was no follow-up or whatsoever on "why sharing needed to be reenabled"…

Just for the record, the shares work, only the "download complete folder" button does not.
