How do you recover from an error like this?
2014/12/26 19:51:34 Error pulling image (oracle-java7) from dockerfile/java, Error mounting ‘/dev/mapper/docker-252:1-6602807-eba5184199800fb03fa4ab8a4e2f1ce3e0ed265891165a258b9eb77425f228ce’ on ‘/var/lib/docker/devicemapper/mnt/eba5184199800fb03fa4ab8a4e2f1ce3e0ed265891165a258b9eb77425f228ce’: device or resource busy
Running CentOS 6.6 with all updates.
The only way to recover from this error is to reboot. I was unable to shutdown docked nor did the output of
lsof or fuser help.
The error occurs when you press ctrl-c during a docker build. This happened already multiple times.
Why is it so hard to make Docker stable against such trivial issues?
