webdav reports wrong disk capacity and usage

[twatzl]

So I have nc set up on my server, there is about 700GB remaining disk space of a total of 5TB, however when mounting the cloud using webdav under Windows it reports a total capacity of 149GB and usage of 147GB. Both values are complete rubbish.

How did I mount it?
Windows Explorer -> Map Network Drive:
Drive Letter: X:
Folder: The webdav url of nextcloud
And connect using different credentials enabled.

When mounting the share under Linux with
$ sudo mount -t davfs https://cloud.myserver.org/remote.php/webdav/ ./cloud -o rw,uid=1000,gid=1000

then df -h reports a disk space of 4.1TB and a disk usage of 4.1TB.

However uploading using the web interface works just fine.

UPDATE: While writing this issue I updated NC from version 15 to version 16 (to make sure the version was not the problem) set a quota and removed the quota again from my user.

Now at least Linux shows a maximum usable disk space of 16E, which is still completely wrong, but at least it is no longer reported as full. I started the file transfer and I will see if it actually works.

Windows still reports the 149GB capacity.

Hello! I can confirm this issue. Got the same problem with NC16 (but I never tried it on NC15)

Can also confirm this issue. Reports as 191GB in windows with only 44,9 GB Free. Quota set to 500GB.

Actual Disk size 500GB. Actual Disk usage 29GB.

NextCloud 17

Same problem with NC18. Reports in Windows 65GB free of 199GB. The storage real size is 1,5TB.

webdav does not provide a way for the client to get the free space from the server, it seems that windows will instead show the used/available space from a local disk instead.

I'm assuming that the linux mounting has a similar fallback.

Either way there isn't anything Nextcloud can do to change this client behaviour

then why not use API based mount like airlivedrive or use winfsp on windows to mount drive for better compatibility?
