F0825 18:19:25.901880       1 deployer.go:64] couldn't assign source annotation to deployment default/docker-registry-2: replicationControllers "docker-registry-2" cannot be updated: the object has been modified; please apply your changes to the latest version and try again

reproducer.sh

oadm registry --dry-run \
--config=/etc/openshift/master/admin.kubeconfig \
--credentials=/etc/openshift/master/openshift-registry.kubeconfig
# wait until it comes up
oc scale rc/docker-registry-1 --replicas=0
# wait
oc volume dc/docker-registry --add --overwrite -t persistentVolumeClaim \
  --claim-name=registry-claim --name=registry-storage
# watch the world burn

This is the pod log for the deployer for rc 2 after I do:

oc volume dc/docker-registry --add --overwrite -t persistentVolumeClaim \
  --claim-name=registry-claim --name=registry-storage
