NetBackup™ Deployment Guide for Kubernetes Clusters

To reduce the log size of the PV

1. Stop the primary pods:

   • Untar the .tar for the kubernetes package, and within the untar folder, navigate to scripts/.

   • Navigate to the scripts folder inside the build folder (For example: VRTSk8s-netbackup-<version>/scripts).

   • Run the script cloudscale_restart.sh, with stop (as the input for action) and the netbackup namespace (for namespace parameter).

     For example: ./cloudscale_restart.sh stop <namespace> This script will pause the primary server CR and stop all the decoupled services.

2. Manually delete the statefulsets:

   • After all the pods are scaled down, get the required list of statefulsets using the command:

     kubectl get sts -n <netbackup_namespace> | grep -e "nbatd" -e "nbmqbroker" -e "nbwsapp" -e "policyjob" -e "policyjobmgr" -e "primary"

   • Delete the statefulsets using the command:

     kubectl delete statefulset <statefulset_names_obtained_above> -n <netbackup_namespace>

3. List the log PVCs for primary pods:

   • Execute the command:

     kubectl get pvc -n <netbackup_namespace> | grep log | grep -ve "catalog" -ve "uss" -ve "media"

     For example: kubectl get pvc -n netbackup | grep log | grep -ve "catalog" -ve "uss" -ve "media"

4. Expand the log PVCs

   • Expand the capacities of the above obtained log PVCs using the command:

     kubectl patch pvc <pvc_names_obtained_above> -n <netbackup_namespace> -p '{"spec":{"resources":{"requests":{"storage":"<Expanded_capacity>Gi"}}}}'

     For example: kubectl patch pvc logs-nbu-primary-0 -n netbackup -p '{"spec":{"resources":{"requests":{"storage":"35Gi"}}}}'

5. Expand log volume size in primary server CR

   • Execute the command: kubectl patch environment <environment_name> -n <netbackup_namespace> --type=json --patch '[{"op": "replace", "path": "/spec/primary/storage/log/capacity", "value": "<Expanded_capacity>Gi"}]'

     For example: kubectl patch environment nbu -n netbackup --type=json --patch '[{"op": "replace", "path": "/spec/primary/storage/log/capacity", "value": "35Gi"}]'

6. Start decoupled services using the cloudscale_restart.sh script:

   • Navigate to the scripts folder inside the build folder (For example: VRTSk8s-netbackup-10.5-0053/scripts).

   • Run the script cloudscale_restart.sh with start (as the input for action) and the netbackup namespace (for namespace parameter).

     For example: ./cloudscale_restart.sh start <namespace>
