# Increase the size of a disk

Increase a disk's size from **Resize Disk** when it fills up. A disk can only get bigger, so the new
size is permanent.

## Before you begin

- Permission to update datasets in the project. A Member gets it through a policy that allows updating datasets.
- A new size above the disk's current size and at most your disk size limit. The limit is
  15,000 GB unless E2E has set a different one for you. To go past the limit, see
  [Request a higher disk size limit](/tir/tir-block-storage/how-to/request-a-higher-disk-size-limit/).

## Resize the disk

1. In **Block Storage (Disk Dataset)**, select the disk's row, then open the **Resize Disk** tab.
2. Set the new size in GB. Each extra GB has a price per month. For rates, see [E2E's pricing page](https://www.e2enetworks.com/pricing). **Reset** puts the size back to
   the current one.
3. Select **Update**.

## Check the new size

The new size can take a few minutes to show. To check it, open **Overview** and read **Disk Size**.

After you resize, the bill follows the new size.
A disk can only get bigger, so an oversized disk keeps its cost until you delete it. To pay
for less, create a smaller disk, copy the data across, and
[delete the old one](/tir/tir-block-storage/how-to/delete-a-disk/). The bill follows the disk's
size, whatever files it holds.

If the instance still shows the old size or a resize is refused, see
[Troubleshooting TIR Block Storage](/tir/tir-block-storage/troubleshooting/tir-block-storage/).
