I’m reposting this here from the iOS app thread, since there was no answer and the problem occurs with the Windows desktop client as well.
I’m administering a self-hosted ownCloud instance (server details below) with about 10 users.
All of these users operate on a shared folder, owned by one of them.
They notified several times the following unwanted behavior:
- sometimes, after one of them has renamed or deleted a sub-folder inside the shared one, this folder reappears either duplicated with the original name or as a new upload (if previously deleted).
The activity log shows the duplicated / re-uploaded folder as created by another user via either the desktop Windows client or the iOS app.
I’ve checked on the server’s filesystem and the folder is indeed physically present on disk (so it shouldn’t just be a database-related bug).
This seems to happen when the client or the app are synced, although it appears to be somewhat random.
- Rename or delete a folder within a shared superior folder
- Another user syncs the iOS app or the desktop client (not clear if related to virtual files in this case).
When renaming or deleting a folder, the clients should see that it has been changed / removed when syncing.
When the other user syncs, the folder is recreated / re-uploaded with the original name.
Apache 2.4.41 on Ubuntu 20.04
MariaDB 15.1 dist 10.3.31 (this happened with MySQL 8.0 as well)
Storage backend (external storage):
2.9.0 (build 5150)
Windows 10 Pro 21H1
Nothing relevant seems to be found in the server logs.
The client log isn’t available.
