Scaling Up Storage Space¶
Scenarios¶
The storage space may be insufficient as your service volumes grow. If the kernel detects that the disk usage exceeds 85%, the DB instance is set to read-only and no data can be written to the DB instance. This section describes how to scale up the storage space of a DB instance.
Precautions¶
Within the maximum allowed range, disk usage cannot exceed 85% of the total storage space after disk expansion.
If any node becomes faulty, contact the O&M engineers for troubleshooting.
The storage space must be a multiple of the number of shards multiplied by 40 GB.
A shard disk has a maximum capacity of 16TB, and 16TB capacity is added each time a shard is added.
Procedure¶
Log in to the management console.
Click
in the upper left corner and select a region and a project.Click Service List. Under Database, click GaussDB.
In the navigation pane on the left, choose GaussDB(openGauss) > Instance Management.
On the Instance Management page, locate the target DB instance and click More > Scale Storage Space in the Operation column.
Alternatively, click the target DB instance to go to the Basic Information page. In the Storage/Backup Space area, click Scale.
On the displayed page, specify the new storage space and click Next.
Confirm specifications.
If you need to modify your settings, click Previous.
View the scale-up result.
During the scale-up, the status of the DB instance on the Instance Management page will be Scaling up. Click the DB instance and view the utilization on the displayed Basic Information page to verify that the scale-up is successful. This process may take 3 to 5 minutes.
