Description Zane Bitter 2021-04-20 17:20:39 UTC 
Upstream merged a patch to make recovery from an empty ironic database (e.g. after a reschedule to another node) more robust, https://github.com/metal3-io/baremetal-operator/pull/845, and this is also required by https://github.com/metal3-io/baremetal-operator/pull/849 to keep adoption of ExternallyProvisioned hosts working. Both of these changes were merged downstream in https://github.com/openshift/baremetal-operator/pull/142.

One of the side-effects of making this more robust, is that the baremetal-operator now writes an update to the ironic Node substantially every time that the Host is reconciled. This should only happen when there are actually changes to make, to avoid unnecessary writes. This is fixed upstream in https://github.com/metal3-io/baremetal-operator/pull/852 but does not yet appear downstream.
