# Increase the size of an SFS

Increase an SFS's size from **Manage Shared File-System** whenever you need more room, up to your
account's size limit. An SFS can only get bigger, so the new size is permanent.

## Before you begin

- The **Dataset** permission in your project policy. SFS shares this permission with Object Storage, Block Storage, and
  Parallel File System.
- Enough project credit for the larger size. The resize checks your credit before it applies the
  change.

## Choose the new size

1. In **Manage Shared File-System**, open the SFS's **Actions** menu and select **Increase SFS
   Size**.
2. In the drawer that opens, set the new size with the slider or the number field. It runs from the
   SFS's current size up to your account's size limit, in steps of 50 GB, and shows the per-GB
   monthly price for your account's currency. For the full price list, see
   [E2E's pricing page](https://www.e2enetworks.com/pricing).
3. Tick "I understand that increasing the SFS size is irreversible and cannot be decreased later."
   **Resize** becomes available once you tick it.
4. Select **Resize**.

You can resize an SFS while it is mounted. The size changes in place, and an instance using the
SFS sees the new size while it keeps running. The files already on the SFS stay where they are.

Billing switches to the new size from the moment you resize, so the time before the resize is billed
at the old size.

Your SFS now holds more storage, at the new monthly price. To see how much of it you are using, open
[Monitor an SFS](/tir/tir-sfs/how-to/monitor-an-sfs/).

## Ask for a higher limit

Your account's size limit is 64,000 GB (64 TB) unless E2E has set a different limit for you. Once
the SFS is at your limit, **Increase SFS Size** lets you ask for more: enter the total limit you
need, in GB, above your current limit, and select **Request**.

The request goes to E2E as a support ticket with your account, project, region, and the size you
asked for. Once E2E raises your limit, come back
and increase the size as in [Choose the new size](#choose-the-new-size).

If a resize fails for another reason, see
[Troubleshooting TIR Shared File System](/tir/tir-sfs/troubleshooting/tir-sfs/).

To remove an SFS you are finished with, see [Delete an SFS](/tir/tir-sfs/how-to/delete-an-sfs/).
