<div style="direction:ltr">Hi Bernd</div>
<div><br>
</div>
<div style="direction:ltr">Thanks - I’ll start looking around at glance and Apache. I’ve told Devstack not to load the sample images and it is now failing further along with a 500 Error so it is certainly something around HTTP.</div>
<div><br>
</div>
<div style="direction:ltr">This is SO annoying because all I am trying to do is to take a working system and clone it into identical hardware. I’m not changing any versions or even any of the layout.</div>
<div><br>
</div>
<div style="direction:ltr">Even if I clone the /opt/stack/Devstack directory, the first thing that stack seems to do is connect out and pull down not the versions of underlying code which worked before but the latest. Even the “upper-requirements” file is
pulled down so I can’t nail that down to what I know works.</div>
<div><br>
</div>
<div style="direction:ltr">I’m going to clean everything out on the new system and just run the most simple Devstack to see if that works.

Apache is the proxy server for Glance in this case. The message says that<br>
Apache doesn't get the expected response from Glance, which could mean that<br>
Glance is not running at all. Check for other errors further up in the log.<br>
<br>
An earlier local.conf not working anymore on a newer DevStack version has<br>
hit me as well at times. You may have to carefully evaluate what you need in<br>
your cloud and throw out everything else. You might also have version<br>
mismatches - remember that enable_plugin has an optional version parameter.<br>

<br>
Following from my earlier email, I’ve traced the problem to a mis-match of<br>
arguments between /opt/stack/nova/nova/db/sqlalchemy/api.py and nova-manage.<br>
<br>
If I change api.py to exclude the retry_on_request from the list of<br>
arguments, nova-manage works.<br>
<br>
This is obviously the wrong thing to do but at least it gets things<br>
underway.<br>
<br>
At least, I get further through the installation.<br>
<br>
I am now seeing another error further down the installation:<br>

Subject: Issue installing OpenStack Pike with Devstack<br>
<br>
Hello<br>
<br>
I’m trying to install a new OpenStack Pike environment using Devstack. The<br>
local.conf is identical to a system built in early October (same base OS –<br>
CentOS7, same interfaces, different IP addresses, but that is all).<br>
<br>
The system in October installed perfectly.<br>
<br>
This system refuses to install falling over at the very first “nova-manage”<br>
<br>

2017-12-06 21:36:38.427 | TypeError: __init__() got an unexpected keyword<br>
argument 'retry_on_request'<br>
<br>
The only difference I can see between the two systems is that the Python<br>
libraries are different versions (oslo.db is 4.25.0 on the old system,<br>
4.31.0 on the new one). <br>
<br>
I have no idea where to start looking.<br>
<br>
Thanks<br>
