# Create and apply an Auto Extend policy to a filesystem

This section describes how to create and immediately apply an Auto Extend policy to a filesystem.

#### Prerequisites

- Login access to the Zesty platform For more information, contact [Customer Support](https://zesty.co/contact-us/?support).
- Agent is installed on relevant instances
- Permission to add tags to volumes

#### To create and apply an Auto Extend policy:

1. From the Zesty platform, select **Zesty Disk**. In the Managed filesystems tab, filesystems that can be managed show the **Select solution** option.

2. By the filesystem that you want to extend, click **Select solution**, then in the Auto Extend Policy section, click **Create new policy**. The Create policy dialog is displayed.
3. Enter a name for the new policy.
4. Configure the policy:
  1. To configure a maximum disk size, beyond which Zesty will not extend, select **Set maximum size** and enter a maximum size (in GB).
  2. Select a preferred policy type, **Simple** or **Advanced**.
    1. For a **Simple** policy, define the **Threshold** and **Configuration**.
    2. For an **Advanced** policy define the **Comfort zone, Risk zone, Start, and End**. The value of **End** should be **Infinity** only for the last tier. To create initial tiers, click + and enter a numeric size in **End**.
  3. Review the policy simulation.
5. Click **Create policy**.
6. Approve applying the new policy to the volume.

The new policy is created and the policy’s tag is added to the volume.
