# How do I unblock my MongoDB database?

If a MongoDB cluster’s storage disk ever becomes completely full, it may suffer severe issues. For example, the cluster may become stuck in a crash-loop, where it indefinitely crashes, restarts, and crashes again during its reboot, until we manually troubleshoot it.

To prevent this, when a cluster’s disk reaches 97% capacity, we automatically block further writes to it. If your cluster is blocked, you receive an email notification.

To remove this block, you can use one of the following methods:

- You can [upgrade your cluster’s maximum disk space](https://docs.digitalocean.com/products/databases/mongodb/how-to/resize/index.html.md).
- You can [open a support ticket](https://cloudsupport.digitalocean.com) and request that we manually override the block.
