Can't delete invalid Federated Share

[michel-thomas]

Hello,
I have a Federated Share that I cannot access anymore, but it is still present in folder view and I cannot delete it (=unregister from it), neither unshare it (this FedShare has been re-shared to other user of my platform).
Many thanks for your analysis.

Steps to reproduce

1. Someone share a folder via Federated Share
2. Share it with other user of the instance
3. Later, this person remove this sharing (don't know how: delete the folder? unshare?)
4. Folder still appears and cannot be removed or unshare

Expected behaviour

Ability to unshare and remove invalid Federated Share folders.

Actual behaviour

Unsharing produce Error deleting file "DOSSIER PARTAGE CPE".
No deleting possibilities.

Hello,
do you need more info to progress on analysis? any idea on how to correct it? and when?
BR,

[icewind1991]

@Esprit-Libre anything in the server log when you try to delete it?

Later, this person remove this sharing (don't know how: delete the folder? unshare?)

Is "this person" here the original owner of the folder?

[michel-thomas]

Yes it wasn't clear, sorry. I rewrite my description:

1. User A from remote ownCloud instance share a folder via Federated Share to a User B of local instance
2. User B share the folder to a user group of the local instance. User C is member of the group
3. Later, User A (the owner) remove the sharing (don't know how: delete the folder? unshare?)
4. Folder still appears and cannot be removed or unshare neither on User B nor C.

When I try to access to this folder with User C, I get these logs:

[RLProteus]

Any update on this? I have a similar issue with a Federated share that I can not remove. The other server has been decommissioned and the server removed from my trusted servers list, but the folder still remains.

It also causes extreme slowness on this account unless I disable the federation and file sharing apps.

[vojeroen]

I have the same issue with a decommissioned federated share that I cannot remove from my nextcloud server.

[steelsnake]

The big issue is that this causes extreme slowdown, the easy-ish fix is to remove the entry from the share_external table.

[vojeroen]

This seems to have fixed it for me. However it would still be useful if users could do this themselves through the web interface. I prefer to not give the other users on our system this kind of access to the database.

[michel-thomas]

@vojeroen How did you fix it? SQL request to update database? Please share your workaround waiting a permanent solution. BR.

@icewind1991 Is there anything I can do to help resolving this issue? Thx.

[vojeroen]

I executed a delete statement on the table oc_share_external to remove the line that linked to the decommissioned server. This effectively removed the shared directory and its contents from my nextcloud system.

[michel-thomas]

@icewind1991 Users can't way anymore, so I delete from oc_share and oc_share_external the invalid link. I can't reproduce the problem for now. Even if I can't help more, any plan for fixing it? I already have the problem before, so I guess it will happen again.
