should use occ files:scan --all instead

and as well the others if needed

  files:scan                  
  files:scan-app-data         
  groupfolders:scan

Thank you for your reply. I will try again today and i will revert with updates.

FSNaval · September 4, 2023, 7:44pm

I carried your advise but still no improvement.

chrissi55 · September 4, 2023, 9:11pm

errors during files scan?
Output?

What do you get by command

grep datadirectory /var/www/nextcloud/config/config.php

→ is the data directiory fully in hand of www user e.g. www-data?

sudo -u www-data ls -l /YOUR-DATA-DIRECTORY

?

FSNaval · September 6, 2023, 4:52pm

What do you get by command :: grep datadirectory /var/www/nextcloud/config/config.php → ‘datadirectory’ => ‘/var/www/html/data’,

FSNaval · September 6, 2023, 4:54pm

→ is the data directiory fully in hand of www user e.g. www-data? sudo -u www-data ls -l /YOUR-DATA-DIRECTORY

Maybe I should nuke the docker container and rebuild from scratch?

I think you have scanned your nextcloud server root directory instead of YOUR-DATADIRECTORY because this is
/var/www/html/data’

so all in /var/www/html/data’ should be owned by www-data:www.data as well

can you give an example of files you see in terminal in your datadir but not in nextcloud?

and then the folder / file status

ls -la …/folder …/file

FSNaval · September 11, 2023, 5:51pm

sorry for my later reply.

I decided to nuke my next cloud instance and start from scratch. Luckily, docker makes it so easy.

SO, I removed everything and reinstalled next cloud. Set up again and everything works as expected now. It took me less than an hour to do so.

Thank you for your time.

I’m facing this same issue. In my case the fiiles vanished from the web interface after upgrading from NC25 to NC26. Then I upgraded all the way to NC28, but I did not get my files back. The files are in the data directory though, so there was no real data loss, but the web interface does not show them.

I tried all the suggestions here above to no avail, except starting from scratch, because in my case I’m not using docker. In another thread someone suggested occ maintenance:repair, which I did, but even that did not help.

However I’ve now reverted the data directory ownership back to my custom nextcloud user, because my Apache is only proxying requests to PHP-FPM, so in my case there’s no point in making the files readable by www-data.

Here is the output of my ./occ files:scan --all

Starting scan for user 1 out of 5 (admin)
Starting scan for user 2 out of 5 (lucio)
Starting scan for user 3 out of 5 (mamma)
Starting scan for user 4 out of 5 (matteo)
Starting scan for user 5 out of 5 (sara)

What could I try next?

Hi, I have the same problem with a fresh Nextcloud Hub 7 (28.0.3) on Ubuntu 22.04.4 LTS. My app syncs the files and apparently everithing is ok with that, and also the files are actually on /mnt/ncdata/… . But in browser, lots of folders says “No files in here”. I appreciate any help with this. On my android phone it works very well, so the problem is “only” with browsers.
