Description Alexander Chuzhoy 2018-10-16 22:54:32 UTC

Document the need to wait 30 seconds after setting or updating the physical network attribute of a baremetal port to ensure neutron's node-to-segment mappings has been updated


Basically after using 'openstack baremetal port set --physical-network...' we need to wait 30 sec before running operations on nodes.
Otherwise users may hit https://bugzilla.redhat.com/show_bug.cgi?id=1633287

Comment 1 Harald Jensås 2018-10-16 23:00:40 UTC

The reason we need to wait 30 seconds is that the ironic-neutron-agent report state to neutron in intervals. The neutron configuration control's the interval via the [AGENT]/report_interval configuration setting. The report_interval is 30 seconds by default.

So to ensure neutrons host-to-segments mappings have been updated after changeing the physical_network attribute of a baremetal port. The user should wait 'report_inteval'-seconds before trying to deploy, clean, rescue etc. operations on a baremetal node.
