For your system the commands would be: fusermount -uz /data mount /data The -z forces the unmount, which solved the need to reboot for me. You … Read more
You might try a lazy unmount: umount -l

It is not possible to use the VOLUME instruction to tell docker what to mount. That would seriously break portability. This instruction tells docker that content in those directories does not go in images and can be accessed from other containers using the –volumes-from command line parameter. You have to run the container using -v … Read more

Specifically: This got easier recently since Docker finally merged a patch which will be showing up in docker-1.7 (We have been carrying the patch in docker-1.6 on RHEL, CentOS, and Fedora).
