Re: [rdo-list] [TripleO] Newton large baremetal deployment issues



Hi,

Unfortunately I am under some pressure to get my stack into production, so now have OSP9 running. I have little opportunity for more testing of Newton.
If I get a window I will send you the info

Regards

Charles

Hi Charles,

So I have finally tried OSP9 and here are the results -

3 Controllers 40 compute - 1 hours 20 mins to deploy.

This is much more the sort of deployment time I was expecting :)

I then tried TripleO Newton Stable again with  3 Controllers 40 Compute -

4 hours and counting.....

The two deployment scripts (for OSP9 and TripleO Newton) were pretty much
identical (allowing for any changes between releases)

During the OSP9 deployment I could use nova list to list the nodes. The
Undercloud API access was in general very responsive.

During the TripleO Newton deployment 'nova list' hangs -
ERROR (ClientException): The server has either erred or is incapable of
performing the requested operation. (HTTP 500)
Undercloud API access was very sluggish.
I noticed Keystone was stuck at 140% for most of the deployment (albeit
multi threaded) which is not the case for OSP9.

I know it is hard to compare two releases, but the difference is enormous.
I will stick with OSP9 for now as this for me works properly out of the box
for  large deployments.
May I ask what version of python-oslo-messaging you have on Newton?

The reason I ask, is that Eck fixed a pretty serious epoll() issue which
caused deploys to fail with newton on weaker hardware (which would work
in mitaka). The change I mention is this one:
https://review.openstack.org/#/c/394963/

It would be great to confirm or not if the python-oslo-messaging package
you are using has this change included.

Thanks,
Michele
