title: How to switch to a different storage driver on an existing docker installation in Redhat Linux 7*
body: <p>I have under /etc/sysconfig/docker , the following configuration :-</p>
  
  <p>other_args="--insecure-registry ******* -g /apps/var/lib"</p>
  
  <p>Now I am using docker version 17.03.1-ce on Red Hat Enterprise Linux Server release 7.4 and default storage driver as overlay that is causing lot of build issues due to :-</p>
  
  <p>checksum_type: too many links</p>
  
  <p>After doing a bit of research on the internet figured out to get rid of this the best solution would be to use overlay2 driver.</p>
  
  <p>How do i edit the /etc/sysconfig/docker to include storage driver as overlay2. I tried lot of ways but none worked. I don't want to reinstall so looking for the easiest approach here that can allow me switch to overlay2 storage driver. I am sure docker tool is robust enough to allow such modifications on an existing installation.</p>
  
  <p>Any help here would be greatly appreciated as always.</p>
