That job is failing at a decent rate, tracking with bug:<br>

It lines up with the novaclient 2.33 release on 10/27, I'm checking<br>
out what the change was that caused the regression.<br>
<br>
This is a heads up that rechecks on this failure probably won't help.<br>
<br>
So far I haven't seen any related patches up to fix it although<br>
there were already 2 bugs reported when I got in this morning.<br>

Heh, well that's 3 bugs then, I didn't see that one. jgriffith and I<br>
were talking in IRC about just handling both exceptions in cinder to fix<br>
this but we also agreed that this is a backward incompatible change on<br>
the novaclient side, which was also discussed in the original novaclient<br>
wishlist bug that prompted the breaking change.<br>
<br>
Given the backward compat issues, we might not just be breaking cinder<br>
here, so I've proposed a revert of the novaclient change with<br>
justification in the commit message:<br>
<br>
<a href="https://review.openstack.org/#/c/239941/" rel="noreferrer" target="_blank">https://review.openstack.org/#/c/239941/</a><br>
<br>
At least with the cinder change above we're OK for mitaka, and logstash<br>
isn't yet showing failures for cinder in stable/liberty, but given the<br>
requirements there it will be a failure in cinder python34 tests in<br>
stalbe/liberty also - so we can backport the cinder fix or block the<br>
2.33 novaclient version on stable/liberty global-requirements depending<br>
on what we do with the proposed novaclient revert.<br>
<br>

I have an alternative to the revert here:<br>
<br>
<a href="https://review.openstack.org/#/c/239963/" rel="noreferrer" target="_blank">https://review.openstack.org/#/c/239963/</a><br>
<br>
That makes novaclient.exceptions.RequestTimeout extend requests.Timeout so that older cinder continues to work.<br>
<br>
I also have changes to block novaclient 2.33.0 in g-r on master and stable/liberty:<br>
<br>
<a href="https://review.openstack.org/#/q/I6e7657b60308b30eed89b269810c1f37cce43063,n,z" rel="noreferrer" target="_blank">https://review.openstack.org/#/q/I6e7657b60308b30eed89b269810c1f37cce43063,n,z</a><br>
<br>
I personally think we need to block 2.33.0 since it breaks cinder, then release a new version of novaclient with either the revert or the alternative change to extend requests.Timeout.<br>
<br>
If we block novaclient 2.33.0 then we can also revert the workaround in cinder (which would start breaking if we reverted the new exception type out of novaclient w/o blacklisting 2.33 first).<div class="HOEnZb"><div class="h5"><br>
