Allocating static PV for Primary and Media pods

When you want to use a disk with specific performance parameters, you can statically create the PV and PVC. You must allocate static PV and PVC before deploying the NetBackup server for the first time.

To allocate static PV for Media and Primary pods

Create storage class in cluster.
See How does the Config-Checker utility work.
This newly created storage class name is used while creating PV and PVC's and should be mentioned for Catalog, Log, Data volume in the environment CR mediaServer section at the time of deployment.
For more information on creating the storage class, see Storage class.
For example,
```
kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
  name: gp2-reclaim
provisioner: kubernetes.io/aws-ebs
reclaimPolicy: Retain
allowVolumeExpansion: true
volumeBindingMode: Immediate
parameters:
  fsType: ext4
  type: gp2
```
For more information about the static provisioning for EFS, see Static Provisioning.

Calculate number of disks required.

The following persistent volumes are required by Media pods:

Data and Log volume disk per replica of media server.

Use the following format to form PVC names.

For primary server:

For media server

data-<resourceNamePrefix_of_media>-media-<media server replica number. Count starts from 0>
logs-<resourceNamePrefix_of_media>-media-<media server replica number. Count starts from 0>

Example 1

If user wants to deploy a media server with replica count 3.

Name of the Media PVC assuming resourceNamePrefix_of_media is testmedia.

For this scenario, you must create total 8 disks, 8 PV and 8 PVCs.

6 disks, 6 PV and 6 PVCs for media server.

For data of PrimaryServer:

For logs:

logs-testprimary-primary-0

Following will be the names for media server volumes

For data:

data-testmedia-media-0
data-testmedia-media-1
data-testmedia-media-2

For log:

logs-testmedia-media-0
logs-testmedia-media-1
logs-testmedia-media-2

Example 2

If user wants to deploy a media server with replica count 5

Names of the Media PVC assuming resourceNamePrefix_of_media is testmedia.

For this scenario, you must create 12 disks, 12 PV and 12 PVCs

10 disks, 10 PV and 10 PVCs for media server.

Following will be the names for primary server volumes

For data:

For logs:

Following will be the names for media server volumes

For data:

data-testmedia-media-0
data-testmedia-media-1
data-testmedia-media-2
data-testmedia-media-3
data-testmedia-media-4

For log:

logs-testmedia-media-0
logs-testmedia-media-1
logs-testmedia-media-2
logs-testmedia-media-3
logs-testmedia-media-4

Create the required number of AWS EBS volumes and save the VolumeId of newly created volumes.
For more information on creating EBS volumes, see EBS volumes.
(For Primary Server volumes) Create the required number of EFS. User can use single EFS to mount catalog of primary. For example, VolumeHandle in PersistentVolume spec will be as follows:
<file_system_id>:/catalog

Create PVs for each disks.

To create the PVs, specify the created storage class and VolumeId (ID of the EBS volumes received in step 3). The PV must be created using the claimRef field and provide PVC name for its corresponding namespace.

For example, if you are creating PV for catalog volume, storage required is 128GB and namespace is test. PVC named catalog-testprimary-primary-0 is linked to this PV when PVC is created in the namespace test.

apiVersion: v1
kind: PersistentVolume
metadata:
  name: catalog
spec:
  accessModes:
  - ReadWriteMany
  awsElasticBlockStore:
    fsType: xfs
    volumeID: aws://us-east-2c/vol-xxxxxxxxxxxxxxxxx
  capacity:
    storage: 128Gi
  persistentVolumeReclaimPolicy: Retain
  storageClassName: gp2-retain
  volumeMode: Filesystem
  claimRef:
    apiVersion: v1
    kind: PersistentVolumeClaim
    name: catalog-testprimary-primary-0
    namespace: test

Create PVC with correct PVC name (step 2), storage class and storage.

For example,

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: catalog-testprimary-primary-0
namespace: test
spec:
  storageClassName: gp2-retain
accessModes:
  - ReadWriteMany
resources:
  requests:
  storage: 128Gi

Deploy the Operator.
Use previously created storage class names for the volumes in primary section and mediaServers section in environment CR spec and deploy environment CR.
