Attaching Vultr Block Storage to a Cloud Compute instance allows the instance to discover the new storage device. You can then mount the block storage to the file system to expand storage. Ensure the Vultr Block Storage and Cloud Compute instances are in the same region before attaching the storage. You can also remove the attachment if you no longer wish to associate the storage with the Cloud Compute instance.
Follow this guide to manage attachments for Vultr Block Storage using the Vultr Customer Portal, Vultr API, and Vultr CLI.

Click Block Storage. Then, select the target block storage instance.
Navigate to Attach to: and select the Cloud Compute instance.
