Description David Vallee Delisle 2020-03-13 15:28:40 UTC

Description of problem:
When HW clock is out of sync, chrony can take a while to sync up (I've seen something like 7 minutes before it was in-sync).

Version-Release number of selected component (if applicable):
openstack-tripleo-heat-templates-11.3.2-0.20200211065544.d3d6dc3.el8ost.noarch

How reproducible:
All the time

Steps to Reproduce:
1. set hw clock on an overcloud node to be like 1h late
2. deploy

Actual results:
"chronyc waitsync 20" fails


Expected results:
Should complete

Comment 1 David Vallee Delisle 2020-03-13 15:29:27 UTC

I'll be backporting the patch downstream.

Comment 2 Alex Schultz 2020-03-13 18:44:45 UTC

Lowering the severity as this seems to be an environmental thing due to ntp servers being used. We always recommend using multiple sources as it'll prevent this from occurring.
