This is a introduced in CoreOS 561 when the default file system was changed from btrfs to the overlayfs. I found a to basically format the filesystem using btrfs when a host is first started, and that seems to be working for now. Amd radeon 6470m download.

Docker Run No Output

This is a similar issue to ' but I'm not sure if it's the same root cause. I'm trying to setup a simple cron docker container, and have been testing a bunch of examples that I can find, including this '. FROM ubuntu:latest # Setup cron and scripts.

# Create the log file to be able to run tail RUN touch /var/log/cron.log # Run the command on container startup CMD cron && tail -f /var/log/cron.log The problem is that this works and the cron jobs run, but nothing appears in the docker logs or output when running docker run. And yes, I have verified that the log file is being written to by running a docker exec command on the container. I then tested changing from ubuntu:latest to ubuntu:trusty, thinking that it might have something to do with Ubuntu 16. This resulted in the following error when starting the container: tail: unrecognized file system type 0x794c7630 for '/var/log/cron.log'. Please report this to bug-coreutils@gnu.org. Reverting to polling After googling that error I found some suggestions.

Docker Log Output

So I tried tweaking my docker file like this: # RUN touch /var/log/cron.log.
