## How to increase server disk size on AWS

Below is an example of AWS EKS.

#### **1. Update Storage Class**

In the K8s cluster, check the storage class: in AWS, it should be gp2.

Then update StorageClass to ensure:

```
allowVolumeExpansion: true
```

Once StorageClass is updated, it should be like:

#### **2. Update PVC**

Once the storage class is updated, then we can update PVC for the server disk size.

Now we want to double the disk size for pinot-server-3.

Below is an example of current disks:

Below is the output of **data-pinot-server-3**

![PVC data-pinot-server-3](https://lh4.googleusercontent.com/yyIaKpAK5xOjbnw3zWKMhi5ybamZxppPKdzwVCsowZuKEPqE8sT5MpssVpZzAdxTNw-2D5u08bsLUIYgdmkwJRzOxzex96lkNq9e_0tTyNcFzP3Z5zs0arQW0IfZtXnScL2_yqhf)

Now, let's change the PVC size to 2T by editing the server PVC.

```
kubectl edit pvc data-pinot-server-3 -n pinot
```

Once updated, the spec's PVC size is updated to 2T, but the status's PVC size is still 1T.

#### **3. Restart pod to let it reflect**

Restart pinot-server-3 pod:

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.pinot.apache.org/release-0.10.0/basics/getting-started/frequent-questions/pinot-on-kubernetes-faq.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
