Painful Weekly Docker Service Failed to Start

Featured Replies

Would be greatful if someone could please take a look at my logs. Thought this was an issue to do with running out of space but has since happened with lots of free space. Hoping someone more knowledgeable can help me out here. Basically every week this seems to happen and I need to delete the docker Img and re-download all dockers. It's getting pretty old now. Thanks!

Were you filling up docker.img? 90G should be 3x larger than needed for most.

An application writing to a path that isn't mapped is the usual cause for filling.

I don't think it was filling beyond about 30g. I did increase it to 90 at one point just because I noticed it close or to try solve this issue I'm having. Will have to monitor.

Any idea why your syslog is being spammed with ntpd entries?

Docker image is running out of space and going read-only

Reboot, do the usual recreate docker.img and reinstall Previous Apps.

Then post new diagnostics and the results from CONTAINER SIZE on the DOCKER page.

OK. I didn't reboot, but rebuilt my dockers 2 days ago. Attached logs. Sorry been super busy. Container size only 2.82GB

I had a custom ntp server. From memory had issues with time. Without I see a 4min difference vs local time. Odd. Have removed for now.

Do you mean the total?

Filesystem                   Size  Used Avail Use% Mounted on
/dev/loop5                    90G   27G   64G  30% /var/lib/docker

What do you get from this command line now that it has been running for a while?

df -h /dev/loop5

I'm back. I ended up disabling the VM backup plugin. I think it was causing the cache drive to become full and everything to grind to a halt.

Filesystem Size Used Avail Use% Mounted on

/dev/loop5 90G 26G 65G 29% /var/lib/docker

docker.img usage not growing. Looks like you would have plenty to spare if you decreased it from 90G to 40G
