Description Tzach Shefi 2018-05-30 14:01:50 UTC 
Description of problem:  Openstack supports enhanced redundancy with dm-multipath on Cinder and Nova. Currently configuring multipath is an error prone manual post deployment config task, which involves installing/starting service(s) plus changing config settings on Cinder/Nova.

Adding Tripleo support for automation of multipath configuration would be beneficial. 

This should probably be an RFE.

Comment 5 Alan Bishop 2019-09-18 03:10:10 UTC 
Please do not change the target release flags. The feature was pushed to osp-17, and will be considered for backports after QE has verified the feature.
Comment 7 Alan Bishop 2020-01-24 14:52:00 UTC 
My initial upstream effort for tripleo to drive the multipath configuration was inadequate. Further work is required, which is why the target has been pushed out to OSP-17. But once the initial work is complete, we will try to backport the solution to earlier releases where feasible.
Comment 8 Gregory Charot 2020-01-24 17:17:03 UTC 
There is a semi manual approach customers can use until it is automated via tripleO

Moving priority and severity back. Please do not set them urgent for situations like this.

I have a status update for today's cinder meeting, but the situation is very complex.
Comment 19 Tzach Shefi 2021-07-05 12:22:19 UTC 
FYI, happened to test this yaml on 16.2 with netapp iSCSI, 
working great for both new deployment as well as updating a pre-existing deployment.
Comment 34 Tzach Shefi 2022-06-30 01:19:43 UTC 
Verified on:
openstack-tripleo-heat-templates-14.3.1-0.20220607161058.ced328c.el9ost.noarch

Successfully managed to deploy a Netapp iSCSI multipathed deployment using multipathd.yaml.
Also tested deployment with a custom multipath.conf file. 

Good to verify.
