Additional info:
* What customer solution does the proposed documentation deliver?
Explains a new tool (ceph-volume) that helps provision OSDs using LVM
as the underlying device technology

* What (if any) existing documentation touches on this customer
solution or problem area?
I've opened a PR with the initial documentation for upstream
https://github.com/ceph/ceph/pull/17068 There is nothing that exists
here already since
this is new tooling.

* Who is the target audience? (i.e. system admin? end user? storage
admin? IT admin? developer?, etc.)
I think everyone except end user. From system/storage admin all the
way to developer (I added some developer-targetted documentation in
the PR)

* What is the level of product familiarity for the intended audience?
(i.e. new customer? existing customer? Red Hat partner?, etc.)
existing and new customer

* Is there any existing upstream activity (or documentation) available
for investigation?
The PR, and before ceph-volume went as part of ceph.git it was
published at http://docs.ceph.com/ceph-volume/master/  (a bit stale
now)

* Is there a specific customer support case(s) associated with this
customer solution?
I am not aware of one.

* Is there any Engineering support available to assist CCS with
creating the new documentation?
Alfredo Deza (adeza)

* What is the time frame expected to deliver the proposed documentation?
