Hi @Byter3 - Unfortunately it is not. The clients, in large part, decide how to sync things. There could also be other factors since upgrading the Server may have also upgraded apps (like groupfolders).
That said, I'm sorry to hear this is happening. |

Hey, |

Because you're talking about a shared folder, a single client could be triggering something that cascades to other clients. I suspect you're also using There haven't been other similar bug reports in the base Server platform though that I'm aware of for the current release. You will probably need to do some legwork to go through the Server logs to try to pinpoint the initial trigger period and what immediately preceded it in your logs. As for the clients, you may want to turn on logging to see what's happening there: https://docs.nextcloud.com/desktop/3.10/troubleshooting.html |
I realized that, I can see hundreds of this message inside the more severely impacted client's dialog box. |

Sounds like possibly nextcloud/desktop#6099 |

#39707 might help? |

Bug description
Nextcloud: 27.1.3 AIO: v7.6.2
Nextcloud delets all the local files from the clients and starts the syncronisation all over. Which is very not funny when you work with terrabytes of data.
The location of the data is a large SMB share mounted in Nextcloud as an external storage and shared to a group. All the users experience he BUG at the same time. Some of the clients deletes everything localy on the clients and some clients just start to sync again every file which is already existing on the client computers. There is no log corresponding to any SMB error. The SMB backend (a seperate NAS device also not showing any errors in it's logs.)
This is an incredibly serious bug.
Steps to reproduce
I guess it's self explenatory in the bug description, but here we go.
Use nextcloud with SMB external storage and wait for the wipe of your client side.
Expected behavior
Not try to resync everything without any trigger. And most importantly not delete any data on the client side, before trying to resync everything unnecessarily.
