qBittorrent: "Errored: Invalid Argument" When Saving to Mounted unraid drive

[Zudnic]

I have an Ubuntu VM running on Unraid v6.9.1, version 22.04.3 LTS.

 

For a long time I have saved torrents via qBittorrent to a mounted disk. Within Ubuntu, on boot, I'd use this command:

 

sudo mount -t 9p -o trans=virtio ubuntudata /mnt/ubuntudata

 

This works fine in the Ubuntu UI - I can see it in the file browser and interact with it normally. ubuntudata is a share on my unraid server.

 

However, lately, qBittorrent does not play nice when saving to this drive. It will start the download, then after about 60-90 seconds, it will pop up that it had a file I/O error and the torrent will show status : "Errored: Invalid argument"

 

This is the same folder I have been using for a long time so I am confident that the problem is not permissions.

 

Thanks in advance for any help.
