I am having some weird problems with my UnRaid server (ver 7.3.2). I get up in the morning and I try to connect to some of my docker containers and they are either down or throw an error message, and when I try and start them backup I get either the following error:

with Gotenberg, Plex-Media-Server, UnraidConfigGuardian

Execution error

Bad parameter

!

Not valid!

or it fails to start. When I check the logs I am seeing: (Joplin-Server)

Container started

[FATAL tini (7)] exec yarn failed: No such file or directory

Container stopped

Or from UptimeKuma

exec /usr/bin/dumb-init: no such file or directory

Container stopped

The only way to get it running again is to remove the docker and image and reinstall from my "Previous apps"

Another weird thing is /var/lib/docker/tmp keeps dissappearing. It is there when I go to bed, but it is gone in the morning, so I can't reinstall containers until I re-create the folder. I am running the CA Auto Update Applications plugin at night. I just disabled the Auto Update and I will see what happens tonight.

Up until about a week ago, my server was running fine.

I get thing running again and then the next morning I have to start all over.

I have attached my Diagnostic file below.

You are using a Docker folder with the native zfs driver, that is a known issue. My recommendation would be to recreate it as a Docker image, since even when not doing that, Docker folders can, in my experience, have strange issues, but if you really want a folder, recreate it using the overlay2 driver.

I forgot to mention that I am seeing 10.83 Load Average and ZFS using most of the CPUs when mover is running.

@JorgeB Switching to use overlay2 driver and reinstalling my containers appears to have solved the problems. I still need to check it tomorrow to make sure.

Thanks you for the quick answer.
