# Why is my cluster rebalancing/resizing?

Clusters are typically in an **active** state, meaning they are operating normally. However, a cluster may instead be in a **rebalancing** or **resizing** state:

- If a cluster is **rebalancing**, we are recycling it for maintenance, troubleshooting, or another internal operation.
- If a cluster is **resizing**, we are in the process of adjusting its storage, as per customer request.

In either case, you can expect no downtime and do not need to take action. If the cluster’s state does not return to **active** for an extended period of time, please [contact our support team](https://cloudsupport.digitalocean.com).
