Steps to reproduce:

• set up a quota of 1 MB for a user
• set up a external storage (SMB for example) for all user (or this specific user)
• upload a file of 2 MB to the SMB mount on web UI: ✅ (as expected)
• add a file to the same SMB mount in a desktop client synced folder: ❌ (should work the same way as in the web UI

[rullzer]

The quota is applied to tightly on the storage I think. I'll see if I can dive into it and else drag @icewind1991 in

[rullzer]

Ok so it is actually happening in https://github.com/nextcloud/server/blob/master/apps/dav/lib/Connector/Sabre/QuotaPlugin.php#L108

As the view of the quota plugin in '/user/files' if then '/upload/foo/bar' is appended things do 💥

[bpcurse]

Steps to reproduce:

• set up a quota of 1 MB for user x
• set up a folder with "group folders" app for a user group the specific user x belongs to
• set a sufficient quota for this folder inside group folders app (e.g. 1 GB) and read/write permissions
• as user x upload a file greater than 1 MB to the group folder on web UI: ✅ (as expected)
• add a file greater than 1 MB to the same group folder in a desktop client synced folder: ❌ (should work the same way as in the web UI)

Is this caused by the same circumstances that were discussed above or is this an independent issue?
(nextcloud server 12.0.2, client Linux 2.3.2, built on git-rev 820899)

I found the issue a patch is on the way.
