Expected behaviour
Csync issue and duplicate folders

Actual behaviour
A few days ago we started to get CSync issues, like CSync failed to access a certain folder or folders and it looks like it is related a to a specific folder or maybe even several folders. At least that is where the issue starts. In this case a “reports” folder.
Sync failed to access: “https://xxx.xxx.xxx.xxx/owncloud/remote.php/webdav/Programs/_current/FL/Guld Breeze/reports”

In addition to this we have duplicate folders in the Gulf Breeze folder as well. When I access the owncloud web GUI I can see the “reports” folder and it allows me to delete it, but the folder comes back. If I try to rename the folder it says it does not exist anymore. So it looks like some parts of the database is corrupt?

We did the following troubleshooting so far:

  • We run repair on the mysql database, yet this did not resolve it and no errors found.
  • We run “sudo -u www-data php occ files:scan --all” yet this did not resolve the issue either
  • We run “sudo -u www-data php occ maintenance:repair” yet this did not resolve the issue either

Any thoughts on this? On how to resolve this issue.

We encountered this bug as well. It would be nice if someone could provide a temporary fix until it gets fixed in the new version. Please help.

Hi,

if you think this is a bug then please report it (obviously :slight_smile:) to the bugtracker. There won’t be any temporary fix in here as bugs won’t be noticed and fixed based on reports here at the forums.

hey @markus007 @slide cross-posting my answer from GitHub · Where software is built

It was opened some days ago in Creation of subfolders using desktop client after a move across shares can lead to duplicated folders. · Issue #28018 · owncloud/core · GitHub and a fix is already in the making (Fix cross-storage move info when moving between two received shares by PVince81 · Pull Request #28022 · owncloud/core · GitHub), keep an eye in the core issue for updates.

Thanks for reporting! :wink:

The fix is done: Fix cross-storage move info when moving between two received shares by PVince81 · Pull Request #28022 · owncloud/core · GitHub

However this is only to prevent the breakage to happen in the first place.

Requires a repairs step to fix the broken filecache entries: Add repair step to repair mismatch filecache paths by PVince81 · Pull Request #28253 · owncloud/core · GitHub
