Files missing after a few hours

,

Hi all,

My files are missing in the Web UI. The files appear again after running repair, but disappear after some time. These files are located in an encrypted partition (I.e. I moved them out of the owncloud folder).

I’m after some guidance on debugging this. I’ve checked the oc_accounts table and everything was ok there. I’ve also read some similar questions but can’t quite work out what is wrong.

Steps to reproduce

  1. Leave owncloud for a day or so
  2. Navigate to /owncloud/index.php/settings/personal
  3. Files are missing

This can be fixed by running

sudo -u www-data php occ maintenance:singleuser --on
sudo -u www-data php occ files:scan --all --repair
sudo -u www-data php occ maintenance:singleuser --off

However, after some time the files are missing again. I’m going to pop that into a corn job but it doesn’t seem ideal?

Expected behaviour

Files should be listed

Actual behaviour

Files are missing

Are you using external storage, if yes which one: No

Are you using encryption: no

Are you using an external user-backend, if yes which one: No

Client configuration

Browser: Firefox

Operating system: Windows

After further debugging, it seems the “hard refresh” in the browser is the key to getting the files to appear, rather than the rescan.

I suspect two interlinked issues here:

  1. A client-side bug in Firefox where files do not appear without a hard refresh (perhaps some weird caching error?).
  2. A server-side issue where for some reason the file list goes out of date?

I’ve disabled the cron job and I update this post with some answers as and when I find them.

After further debugging.

  1. The client-side bug only exists in firefox but not in chrome.
  2. The file list only needs to be refreshed after a reboot.

I suspect issue 2 occurs when owncloud tries to access the file system before I decrypt the partition, so this is a non-issue and that part is closed, IMHO.

Issue 1 looks like a firefox bug. Possibly related to the following
a) My Files Not Showing In Firefox Browser

I have opened https://github.com/owncloud/core/issues/38451 to track this issue and for completeness.
