Groupfolders are shown empty after upgrading to 18.1.5 / 19.1.4

[oleua]

Hi!

I've updated the app from 18.1.4 to 18.1.5 and now all my groupfolders are shown empty, though the files are present in the directories.

In logs I see constantly:

NC 30.0.14

UPDATE: reverted back to the previous version, and it works (needed to update the configvalue in the nc database manually).

UPDATE2: as a result all desktop clients erased groupfolder data from local PCs and need restart and resync.

Same here with v19.1.4. Some users will have to download 100+ GB over a slow line again...

[JanBoehme]

We had the same issue, with v19.1.4 on NC 31.0.8. Couldn't find anything relatable in the server log though.

Hi, we are looking into this!

[come-nc]

The trace of the error does not match the code in release 18.1.5:

      {
        "file": "/www/html/nextcloud/apps/groupfolders/lib/AppInfo/Application.php",
        "line": 124,
        "function": "__construct",
        "class": "OCA\\GroupFolders\\Trash\\TrashBackend",
        "type": "->"
      },

The call is on line 126, and it does contain the expected 11 parameters. So I’m suspecting an upgrade issue, with the old code still being in memory while calling the new class, or something like that?

[come-nc]

@JanBoehme @nerdlich @ostasevych Can you tell us if the issue persists after server restart (to clear caches) or if the groupfolders stay empty even then?

Can you also look in you log file if you have the same error as the original poster or if you have other errors?

I have the same issue since updating to 19.1.4.
Nextcloud is 31.0.8

Group folder is shown as empty. The files are still at the disk.
Server completly rebooted, nothing in the logs.

[nursoda]

Same here, but only for ONE of the team folders!

I have the same issue since updating to 19.1.4. Nextcloud is 31.0.8

Group folder is shown as empty. The files are still at the disk. Server completly rebooted, nothing in the logs.

Update:
I've checked another hosted nc instance. It has the same versions as the self hosted instance. There is no problem. I don't have information about the hosted instance. But at the self hosted instance the data directory is a samba mount. Maybe it is a hint.

[nursoda]

Not in my case. Here, it's a local folder (ext4).

[artonge]

@nursoda is the working groupfolder different from the other? Maybe a fully numeric name, or no ACLs, or anything else?

All:

1. Are you able to create new files inside the empty groupfolders?
2. Are you able to create a new groupfolder and create files in it?

Same here with Nextcloud 31.0.8 updating to 19.1.4. To downgrade to 19.3.1 I have deactivated groupfolders app then used following commands in apps folder:

rm -r groupfolders
wget https://github.com/nextcloud-releases/groupfolders/releases/download/v19.1.3/groupfolders-v19.1.3.tar.gz
tar -xvzf groupfolders-v19.1.3.tar.gz
rm groupfolders-v19.1.3.tar.gz

Then I have reactivated the groupfolders app.

I hope it is a safe way to downgrade.
