When you get error like below.


DR sync failed.
Detailed Error: Data sync of the below K8S volumes failed:
transact-prod/prod-tafjud-pvc: 
rsync: write failed on "/OHB_Storage_Pool/mnt/swift-images/stage1/JobId-3142-swift-image-prod-tafjud-pvc/como/batch-6f8955996f-q2ngp/tSA_70011_20250717_07-21-42": No space left on device (28)
rsync error: error in file IO (code 11) at receiver.c(399) [receiver=3.1.2]


Then we have to follow below steps to narrow it down.


To increase the source volume, we can proceed with the following steps as a workaround.


- Delete the PVC  at target

- Grab the source errored PVC  YAML.

- Recreate the PVC with following YAML at DR site.


eg.


apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: <pvc-name>
  namespace: <dr-namespace>
spec:
  accessModes:
  - ReadWriteMany
  resources:
    requests:
      storage: 200Gi
  storageClassName: oci-fss
  volumeMode: Filesystem



- Start the stage1 sync with following details.

Cluster name: <dr-cluster-name>
namespace: <dr-namespace>
imagegroup name: <provide-ig-name>
 
then go to 'Advanced option' tab > 'Volume sync config'  > select volume from dropdown  , click on +
start the sync by clicking on 'Add' 


-Then IG will be created and we can do forward sync from source to target with stage1+2.
