openshift-target-os-image-issue

### One of the MCP degraded, machine-config-daemon show error log : expected target osImageURL
### Pause of the update procedure (in console), then on the degraded node:

# ssh core@degraded-node
# sudo -i
# rpm-ostree rollback 
# systemctl reboot

### After the node is up again, force the node to re-pull the image and extract the osImage :

# /run/bin/machine-config-daemon pivot "quay.io/openshift-release..."

### where "quay.io/openshift-release..." was the same as on the other non-degraded node.
### After the command has been completed run, check the status of the current image
### Current one has "*" at the beginning of the first line, for example:

# ssh core@degraded-node sudo rpm-ostree status
State: idle
