Description of problem:

Currently OpenShift only monitors disk space for the root partition and the Docker cache.
However for various reasons, separate partitions may be used for /var or /var/lib/origin and/or /var/lib/docker.

So OpenShift should either monitor disk space on all mounted partitions or for the directories that it specifically cares about.

Version-Release number of selected component (if applicable):


How reproducible:
Very

Steps to Reproduce:
1. Move /var/lib/docker to separate partition
2. Disable any cap on docker log file size
3. Run elastic search with a bad NFS share configured as a persistent volume
4. .......

Actual results:


Expected results:

Note that this is really something that needs to be addressed upstream in Kubernetes and/or cadvisor.

This bug has been identified as a dated (created more than 3 months ago) bug. 
This bug has been triaged (has a trello card linked to it), or reviewed by Engineering/PM and has been put into the product backlog, 
however this bug has not been slated for a currently planned release (3.9, 3.10 or 3.11), which cover our releases for the rest of the calendar year. 

As a result of this bugs age, state on the current roadmap and PM Score (being below 70), this bug is being Closed - Differed, 
as it is currently not part of the products immediate priorities.
