Scaling Up Storage Space

Scenarios

This section describes how to scale up the storage space of a DB instance to suit your service requirements.

During the scale-up process, the DB instance will not restart, and your services will not be interrupted.

Setting the Disk as Read-only When the Disk Space Is Full

To ensure that the GeminiDB Mongo instance can still be used if the storage space is about to be used up, the database is set as read-only, and data cannot be modified. If this happens, you can add more storage to restore the database to read/write status.

Precautions

• Storage space can only be scaled up.
• To view storage details on the Instances page, contact customer service.
