What Should I Do When a Large Number of Binlog Files Cause Storage Space Insufficiency During an RDS MySQL Instance Migration?

During an RDS for MySQL DB instance migration, a large number of binlog files are generated in a short period of time, causing insufficient data disk space (disk usage: 91%) and affecting services.

Solution

  1. Clear expired data in a timely manner.
  2. As your service data grows, the original storage space may be insufficient. If this happens, scale up storage space for your DB instance.

    For operation details, see Scaling up Storage Space.

  3. Cloud Eye monitors database metrics, such as the CPU usage, memory usage, storage space usage, and database connections, and allows you to set alarm policies to identify risks in advance.

    For operation details, see Configuring Displayed Metrics.
