I seriously think that there should be more documentation provided like this with the latest ongoing versions in Docker
https://jpetazzo.github.io/2014/01/29/docker-device-mapper-resize/
I find myself in a similar spot like this guy
but it seems like there is limited help and documentation available on this for beginners w.r.t Linux Filesystem.
Folks are not even viewing in stack overflow if they see anything related to Docker devicemapper storage issue.
Would make life easier if there is someone out who could help and also kindly improve the documentation on this subject.
Thanks,
