# Issues with Disk Quota Exceeded
Problem: When a client has reached or exceeded their disk space quota, they might encounter issues when attempting to perform file operations such as creating staging instances, uploading files through the control panel, or any other file-related operations. These operations may fail silently or with error messages containing Disk quota exceeded
.
Solution: If you notice error messages like Disk quota exceeded
in your logs when users try to perform file operations, follow these steps:
- Check if the subscription has a disk space limit configured
- Verify if there is also a disk quota in place
- Ensure both limits are aligned appropriately
- Consider increasing the disk quota if it's more restrictive than intended
