Bug description

When mounting an external storage to a user's root (/), several quota features stop working properly:

  • Setting a quota effectively sets it in the database, but the API returns another user's quota (found in the browser's console via /ocs/v2.php/cloud/users/details?offset=0&limit=25&search=)
  • Setting a quota sometimes doesn't show it in the user's files app (I've come to the conclusion that if the quota shows as unlimited in the admin panel, it won't show on the user side. But, if a quota is shown on the admin panel, even if it's the wrong one, it'll show the correct one on the user side.) Uploading a file sometimes refreshes and shows the limit again.
  • Quota doesn't always update, even with quota_include_external_storage set to true and filesystem_check_changes set to 1.
  • You can upload files past your quota, even when the frontend clearly states External storage "" is full, files cannot be updated or synced anymore!. You can still update existing files and upload new files.

Steps to reproduce

  1. (Create multiple users? My test install has 3 users, 1 of them is the built-in admin.)
  2. Add a quota limit to a user
  3. Install the External Storage app, then map a Local storage from / to /mnt/ext/$user (this also works with a normal, global mapping)
  4. Open the Users view, you'll notice that the quota has indeed vanished, but is still present in the database (and maybe in the user's Files app)
  5. Set a different quota to another user
  6. Reload the page, you'll notice that either a) the quota has vanished for both users or b) one of the two users will have a different quota than what is set in the DB.

Expected behavior

  • Setting a quota in the Users view should persist and return correct values
  • Said quota limit should show in the user's Files app and report correctly to the API
  • Quota should update reliably when uploading a file
  • Users shouldn't be allowed to get past their quota limit
