# Create a new Zesty Disk filesystem on Linux

This topic describes how to create a new Zesty Disk filesystem on a clean volume attached to a Linux instance.

After the completion of this operation, you have a new Zesty Disk mount point that will expand and shrink automatically.

### Prerequisites

- User access to the Zesty platform
- Root user access to the instance with the created, empty volume
- The Zesty Disk Agent is running on the instance
- (Recommended) Before creating the first filesystem, verify AWS permissions, as described in [zestyctl verification command - Verify Linux instance permissions](/v1/docs/zestyctl-verification-command-verify-linux-instance-permissions).

#### To create a new Zesty Disk filesystem:

1. From the Zesty platform main menu, select **Zesty Disk**.
2. From the Managed Filesystems tab, click **Install agent**.
3. In the Install agent dialog, expand the **Linux** dropdown.
4. SSH or Putty into the prepared instance as a root user.
5. Copy the second command and run it on the instance: `zestyctl disk mount <device> <path>` For example, to create the` /mnt/data` mount point on the `/dev/xvdb` filesystem, run: `zestyctl disk mount /dev/xvdb /mnt/data`

When the process is complete, a confirmation message is displayed: `Zesty Device mount completed`

After the Agent reports back, you can see the new Zesty disk mount point in the Managed filesystems tab. You may have to click **Reload**: ![](https://cdn.document360.io/0eb80240-664b-49f5-9181-5713ddf9f725/Images/Documentation/zesty_disk_create_a_new_filesystem(1).png) The new Zesty disk (A) has a capacity of 45 GB (B). Zesty took a 20 GB mount point and added an additional 25 GB mount point to enable expansion for user writes.

You can see the Zesty Disk earlier on the instance by running` zestyctl disk list`. Output similar to the following is shown:![](https://cdn.document360.io/0eb80240-664b-49f5-9181-5713ddf9f725/Images/Documentation/create-a-new-zesty-disk-filesystem-image-4yskip90.png) ![](https://cdn.document360.io/0eb80240-664b-49f5-9181-5713ddf9f725/Images/Documentation/create-a-new-zesty-disk-filesystem-image-1l0lypab.png) **xvdb** is a Zesty Disk. (**xvda1** is not a Zesty Disk. You can use Zesty EZswitch to migrate data to it and turn it into a Zesty Disk. For more information, see [Migrate Existing Data to Zesty Disk](https://docs.google.com/document/d/1VrZ4LKTKHhVnj2BqN0uKvrtKY9kawsxeBKpX4bpwPxs/edit#heading=h.5lxen3mfg2qw).)

In the following figure, you can see the two mount points (**xvdb** and **xvdc**) that were created in the instance:
