Description Bryan Yount 2015-04-07 05:33:17 UTC 
Description of problem:
The nova installer in RHEL-OSP 6 does not require device-mapper-multipath as a dependency. This led to a delay in my customer's rollout of a new RHEL-OSP 6 environment due to troubleshooting efforts. I am opening this BZ to ensure that the new installer takes into account that an @base install of RHEL 7 does not include dm-multipath and it should install it.

Steps to Reproduce:
1. Install RHEL 7 Base
2. Install RHEL-OSP Nova
3. Connect to fibre storage
4. Try to deploy instances

Actual results:
Customer reports "odd results" when multipath was not installed

Expected results:
Multipath should be pulled in by the Nova installer as it is a required component of OpenStack.

Comment 5 Mike Burns 2015-04-16 15:28:25 UTC 
There are a few different solutions to this:

* Fix the RHEL cloud image to include the package (probably the *right* choice)
* Add an explicit dependency on device-mapper-multipath to one of the storage related components (cinder, glance, swift, nova) (probably the quickest solution)
* Add to a DIB element to include the package in the image
Comment 7 Lon Hohberger 2015-04-16 15:58:02 UTC 
It looks like this needs to be a dependency of openstack-cinder and openstack-nova-compute (both) to fully resolve the issue.
Comment 8 Mike Burns 2015-04-16 15:59:08 UTC 
After reviewing this, we decided:

1.  not a good choice.  The image itself targets guest images which would *not* want dmm
3.  more involved but doable

#2 is the right choice and simplest path forward.  It should be added as a dependency to both openstack-nova-compute and openstack-cinder

I'll move this bug and clone it appropriately now.
