Rsync pod is now using default values when limitrange values are nil.
Created a limitrange resource with nil memory values.
$ oc get pods rsync-jrkrd -o yaml
resources:
limits:
cpu: 500m
memory: 1Gi
requests:
cpu: 100m
memory: 1Gi
Created a limitrange resource with nil cpu values
$ oc get pods -o yaml rsync-kcvn6
limits:
cpu: "1"
memory: 1Gi
requests:
cpu: 100m
memory: 1Gi

Description of problem: I created a limitrange resource on source project with cpu values only. I was expecting rsync to use the default memory values instead of 0. Version-Release number of selected component (if applicable): Source Cluster : 4.6 GCP Target Cluster : 4.9 GCP MTC 1.7.0 OADP 0.5.5 How reproducible: Always Steps to Reproduce: 1. Create a new project in the source cluster. $ oc new-project test-dvm-limitrange 2. Create a limitrage object apiVersion: v1 kind: LimitRange metadata: name: cpu-min-max-lr Namespace: test-dvm-limitrange spec: limits: - max: cpu: 500m min: cpu: 100m type: Container 3. Deploy an application with pvc in source cluster $ oc new-app django-psql-persistent 4. Create a migplan from ui 4. Execute cutover 5. Check rsync pods resource limits Actual results: Rsync pod is using memory requests and limits as 0 Expected results: Rsync pod should use default values when the limitrange values are nil. Additional info: Added a rsync pod yaml below. $ oc get pods rsync-h7qmv -o yaml image: registry.redhat.io/rhmtc/openshift-migration-rsync-transfer-rhel8@sha256:de52c65c9022c3e310c88f3bb34f306427b5eb2fcde7c0f5b7be2abf6692d57e imagePullPolicy: IfNotPresent name: rsync resources: limits: cpu: 500m memory: "0" requests: cpu: 100m memory: "0"
