Tweaking docker devicemapper storage in Red-Hat based distributions

If you are using docker on Red-Hat based distributions, then devicemapper is your default filesystem for backing docker.

In case you want to change some of its default settings (i.e. if pool size of 100Gb is not enough), have a look at the “real docs” for RH7 or at this page for other distributions.

If you want to dig deeper, in this other page you will find a pretty detailed comparison of the different filesystems options available for RH.
