"No space left on device" error during Docker install, despite free space on disks (screenshots & diagnostics attached)

Featured Replies

Hi everyone,

I'm running the latest version of Unraid and I'm having trouble installing Docker containers. I get the following error when trying to install:

write /var/lib/docker/tmp/GetImageBlob3255216196: no space left on device

I've checked the disk space and I see that Docker has 7GB allocated, and there's about 3TB of free space on the disks themselves. I don't understand why Docker can't use the available space.

I've attached a screenshot of the error message and a diagnostics zip file. Any help would be greatly appreciated!

Thanks in advance for any tips!

Your Docker image file is the standard 20GB but you're trying to install a humongous container. Change it to 50-60GB.

How can I change this?

Settings->Docker, disable, apply, change size in the field that appears, enable again
