Hi Mike Perez,

Is it possible to add one item to get feedback about which messenger type is used in deployed cluster? TCP-Posix or DPDK or RDMA?

Subject: Re: Need feedback for Ceph User Survey 2019

Here's another draft with the current feedback. Sage, do you have thoughts on keeping any of the data protection questions per Lar's suggestions?

I did another pass and I think we can simplify.  I suggest we give up on
the detailed per-cluster stats from a manual survey and instead rely on
telemetry (and/or telemetry backport to mimic/luminous if we *really* want
that data), and then consolidate this into a handful of easy questions in
the general survey.

On the general part,

- telemetry 'why' question: make it a "check all that apply" + comment

...the add:

- How many clusters do you operate?  [fill in number]
- Which Ceph releases do you run?  Check all that apply
   (list nautilus -> argonaut)
- Total aggregate cluster capacity in TB [fill in number]
- Largest cluster capacity in TB [fill in number]

and then copy most of the other cluster answers back over to the main
one, converting anything that is a selection to a 'check all that a
pply'.  e.g.,

- Which Ceph packages  (copy/move from cluster survey, but check all that
apply)
- What operating system(s) are you using on cluster nodes?  (copy/move,
but check all that apply)

A few things could be dropped to simplify:

- how many hosts, osds, osds per node, osd backends, redundancy
- number of hours (unless we can simplify this?)
- data protection scheme
- size/min_size
- which osd layout features
- what type of NICs
- RGW: 'do you use snapshots?' subquestion (not a thing)

Change:
- What process architectures
  - add Power
- Typical number of fs clients (per cluster)                     
- number of files ... (for largest cluster, if multiple clusters)
- MDS cache size ... (for largest cluster, if multiple clusters)
- number of active MDS for largest cluster [just type in value, not a
multiple choice]

A few of these still fall into the category of things we should capture
with telemetry.. I'm not quite sure where to draw the line, but generally
think we should lean toward simplicity.  Like, all of those Change items
:)

Lars, WDYT?
