Description David Peacock 2016-01-28 18:10:28 UTC 
Description of problem:

In certain circumstances, it's possible to find an introspected node doesn't has differing resources than there are matching flavors.

This leads to a fairly unhelpful error stating hosts aren't available upon deployment time.

This RFE came about after speaking with Ryan Brown; we realized it could be trapped cleanly with a clear error message helping the operator realize exactly why the host wasn't considered appropriate.

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


How reproducible:

Always

Steps to Reproduce:
1. Create a flavor with a resource such as RAM that's higher than is available on the physical node in question.
2. After introspecting the overcloud nodes, run the overcloud deploy and find a 500 error.

Actual results:

500 error

Expected results:

A clear message that the node found doesn't sufficient resources to match the flavor in question.

This bug did not make the OSP 8.0 release.  It is being deferred to OSP 10.
Comment 5 Jaromir Coufal 2016-09-30 08:12:35 UTC 
Ironic node tagging is used instead of nova flavors now.
