How to Reset a cPanel Account's Disk Quota in WHM

How to Reset a cPanel Account's Disk Quota in WHM?

Sometimes a cPanel account may show incorrect disk usage — either showing full when it is not, or showing 0 when files clearly exist. This is a quota sync issue that can be fixed by resetting the disk quota in WHM.

Signs of a Disk Quota Issue

• Client reports disk full error but File Manager shows plenty of free space.
• WHM List Accounts shows 0 MB used even though the client has a live website.
• New files cannot be created or emails fail with "disk quota exceeded" despite available space.
• cPanel disk usage bar shows full but actual files don't add up to the limit.

Fix Disk Quota via WHM – Quota Resync

1. Login to WHM.
2. Use the search bar and type Quota.
3. Click Manage Quota or Force Quota Recalculation.
4. Select the affected account username.
5. Click Recalculate or Fix Quota.
6. Wait for the process to complete — it may take a few minutes.
7. Go back to List Accounts and verify the disk usage now shows correctly.

Temporarily Increase Quota as a Fix

If the quota resync does not work immediately, you can temporarily give the client more space:

1. Go to WHM → Account Functions → Modify an Account.
2. Find the account and click Modify.
3. Increase the Disk Space Quota (MB) by 500–1000 MB temporarily.
4. Click Save.
5. This usually resolves the immediate issue while the quota recalculation runs in the background.

Note: Quota sync issues often occur after large file operations like restoring a backup or running Softaculous imports. Running a quota recalculation after such operations is good practice.
