BlockingIOError: [Errno 11] Resource temporarily unavailable

[jcviquez]

I'm having a really similar problem. Reinstalled after recreating my docker VM and only arch-delugevpn is having problems after the migration.
Data folder mapped to smb mount on my VM with fstab. I tested the permissions several times both on the VM and from the container console and I can create, delete and move files normally. I did noticed that when I check with ls -l on the console I get a similar error about Resource temporarily unavailable and then the folders and files get listed normally.

Every time I bring the container online, it starts re-checking multiple torrents marked with errors and I can download and move downloads for a while, but after a few mins I no longer can download or move things.

I use Deluge as Thin Client and noticed I cannot see the remaining free space on the status bar next to the HDD icon as usual, which I guess relates to the error on the log about get_free_space

Yeah we have the exact same problem then, i also have the error where it used to give me my remaining space on the webui. I also changed the PID, and GID to the root user to make absolute sure im not having perm issues.

I can create, move and delete files as both my ubuntu user and the root user. Its just the docker container thats having issues for some reason.

Perhaps a update between September 2023 and now broke stuff?

If the torrent is small, it will download with no issues and sonarr/radarr will move it to the correct folder with no issues. The problem is when the files are bigger it will error out so much that it just downloads a corrupt mess which is unusable if you manually resume it everytime it errors.

I also tried using a previous version of arch-delugevpn using the tag [2.1.1-4-05] pushed 5 months ago instead of latest, but I had the same problem. Unfortunatelly I'm not sure what version of the image I was using before.

Hi @RobCod, I was looking for similar problems recently reported with other software and found someone using Immich with a similar setup (TrueNAS, Ubuntu VM, Docker, SMB Mount) with resource temporarily available errors and the problem seems to be related to the current linux kernel (Linux 5.15.0-102-generic) on the host VM Ubuntu machine.

As a temporary workaround the suggestion for Ubuntu 22.04.4 LTS is to either downgrade to Linux 5.15.0-101-generic which I did try and indeed solve my problems with arch-delugevpn or upgrade to 6.5.

Not sure why only this container showed problems, or if the others had some that went unnoticeable for my use cases.

Exactly the issue, danke
