"Status: No such Device" for all new downloads in "latest" tag, rolling back versions solves it

[snowwolf3388]

Hello,

I was running lscr.io/linuxserver/deluge:latest and every single torrent that I added would fail to start with an error. The best "log" I could find on the issue was just in the torrent status which said Status: No such device.

A little googling didn't bring up much except this post (https://askubuntu.com/questions/1395966/no-such-device-when-trying-to-download-any-torrent-on-deluge-inside-docker-con) which suggested rolling back to a previous version of the container. I did, to the one they suggested: 2.0.5-0202202181752ubuntu20.04.1-ls140, and restarted all the torrents and they all are working flawlessly.

Sorry, I'm not much more technical in my understanding than this, but there is something clearly going on. If I go back to latest, they break again, it is repeatable.

It may help to know that I'm using MergerFS for my Linux file store mount, which some other articles have hinted at a potential issue. However, I assume many are using this arrangement, so I'm surprised others aren't having the same issue.

Let me know if there is any other information I can provide for diagnostics.

Hi there,

I found this issue and it describes exactly the behavior I'm currently seeing.
Rolling back to said version solved it for me too, but I'd love to see a better fix for this.

How can I help?

Shall I open a new issue using the template?

Best

Let me summarize what I'm currently experiencing:

Current Behavior

Using image lscr.io/linuxserver/deluge:latest

To reproduce the error: move a downloaded file - using deluges "Move Download Folder" functionality - to a MergerFS folder and perform a "Force Recheck". The status of the file switches to error: No such device. The error also shows up in the logs (below).

I can move the file back to a non-MergerFS folder (just a folder on a mounted HDD) and do a force recheck again. The error message disappears and the file can be seeded again (see logs).

As the OP suggested, I tried the same using the image

lscr.io/linuxserver/deluge:2.0.5-0202202181752ubuntu20.04.1-ls140

and indeed, moving and rechecking the files from and to MergerFS folders works without any problems.

System

• OS: Ubuntu 20.04.5 LTS x86_64
• How docker service was installed: apt

Logs

Perform "Force Recheck" on the relocated file, which is now in a MergerFS folder:

Turns out this problem can be solved by changing the way how the MergerFS mounts are set up.

See this issue on the matter: trapexit/mergerfs#463

With this fix it the problem described above is resolved, I'm able to move and force recheck files using the lscr.io/linuxserver/deluge:latest image.

[snowwolf3388]

Awesome. Thank you. It took some reading and I wasn't 100%, but I tested this and it works now. For anyone else with the same issue, the problem is that in the MergerFS options, you must not have cache.files=off, which is the same as have direct_io=true (this option is depreciated, though). I changed mine to cache.files=partial and switched back to the 'latest' tag and everything is working great!
