RetryFilter: What to do with a failed host?
If I understand RetryFilter correctly, a host that once failed will be filtered out forever. Is that correct? If so, how can I convince the filter that the host is available again?
By the way, on my Juno installation on Centos 7 I find the following in the nova-scheduler.log:
Host [u'compute1', u'compute1'] fails. Previously tried hosts: [[u'compute1', u'compute1']] host_passes /usr/lib/python2.7/site-packages/nova/scheduler/filters/retry_filter.py:42
It's a bit unclear to me what that means. First it says that compute1 fails, then it says that it passes. Which of the two?
