Challenge

A Veeam Kasten for Kubernetes DR Restore fails with the following error:

Internal error occurred: {"message":"Could not retrieve artifacts for prefix search","function":"kasten.io/k10/kio/rest/clients.FetchArtifactsForSearchPrefix","linenumber":52,"fields":[{"name":"key","value":"api-meta-label_restoreactions.actions.kio.kasten.io_k10.kasten.io/policyName"},

Cause

The issue occurs after a Disaster Recovery (DR) Restore is initiated but fails due to some complication. During the DR restore process the catalog service is scaled down, so when the DR Restore is re-initiated, it searches for the catalog which is not available at that time because it has been scaled down. 

Solution

The following steps would help resolve this particular issue:

  1. Check the status of the restore pod in the kasten-io namespace. If DR restore fails, the pod status will be shown as 'failed'.
kubectl get po -n kasten-io
  1. Check the catalog pod status. Make sure the catalog pod is running. If it is not running, scale the catalog deployment using the following command:
kubectl scale deploy/catalog-svc --replicas=1 -n kasten-io
During the DR restore, catalog-svc deployment will be scaled down to recover the catalog. If the DR restore fails for some reason, when re-initiating the restore, you must scale up the catalog to 1.
  1. Uninstall k10-Restore helm chart (previously failed)
helm uninstall k10-restore -n kasten-io

  1. Re-initiate the Veeam Kasten for Kubernetes DR restore process.

  2. Check for the status of the DR Restore Chart, Restore Pod, and Catalog Pod.

helm list -n kasten-io
kubectl get po -n kasten-io
#If its successful - catalog pod should show up as running and restore pod will be terminated upon DR Completion
