File Storage Scaling (Expansion and Reduction)

In Compute Cloud or containerized application environments, file storage scaling refers to dynamically adjusting the capacity of shared file storage according to business needs. Scaling up lets you quickly add storage space as data grows, avoiding business interruptions caused by insufficient capacity; scaling down lets you release excess storage resources after data cleanup or a decline in business scale, reducing costs.

File storage scaling supports online adjustment without service interruption. During the adjustment, all container instances that mount this storage can still read and write data normally. This capability suits scenarios with large data fluctuations or a need for long-term, stable access to shared files, such as log archiving, model training datasets, and media file processing.

The following demonstrates how to scale file storage in d.run.

Prerequisites

  • The selected region must have file storage initialized.
  • Your account balance must exceed the required cost for expansion.

Steps

  1. Log in to d.run, and go to Compute Cloud -> File Storage.

  2. On the File Storage page, click Scale in the upper right corner.

  3. In the pop-up Scale window, enter the desired storage quota, and click OK.

Billing Rules

  1. Billing rule: Storage exceeding the free 20 GB is billed daily. If usage is less than one day, charges are based on actual usage time, accurate to the second.
  2. Billing period: Billing starts from the moment of expansion and continues until the next expansion or reduction. If storage is reduced to 20 GB, billing stops. If scaled to any other size, a new billing cycle begins.
  3. Overdue payments: If your account balance falls below 0 and you have previously expanded storage beyond the free 20 GB, the system will retain your data for 15 days and continue billing during this period. You may manually reduce the storage during this time. If reduced to 20 GB, billing stops. If your balance remains negative for over 15 days, the system will automatically reduce storage to 20 GB. Any data lost due to automatic reduction cannot be recovered—please top up your account in time.
  4. Prolonged inactivity: If there is no spending activity on the platform for 30 consecutive days (including but not limited to services like Compute Cloud or Large Model Services), the platform will automatically delete the file storage. You will need to reinitialize it upon the next use.
