title: Loop over ansible_devices and select any physical disk that is not sda for inclusion into volume group
body: <p>I have a requirement to build two logical volumes.  sda1 will always form /root and be partitioned up for logs and such, but /application may include anywhere from one to four additional disks.  I know they will always begin with sdb and continue on to sde or sdf.  I can think of a couple of different quick and dirty solutions like just running a bash command that builds a list to be registered as a variable, but what I would like to do instead is pull down from the ansible_devices part of Ansible setup facts and match a regex of sd[b-z].  I know it's unlikely I will ever have an sdz, but I want to keep this as flexible as possible.  Does anyone have a good technique for this? Is a jinja2 filter the wrong approach?</p>
