Block Storage: How to Create, Attach, and Resize a Volume
Create a persistent block storage volume, attach it to an instance, and scale capacity without redeploying.
9 min read · Updated 2026-04-01
Prerequisites
- • Instance in ACTIVE state within the target project
- • Available block storage quota
- • Permissions to manage volumes and attachments
Implementation workflow
This runbook focuses on a reliable sequence for provisioning and validating the service through the cloud console.
- Open Storage > Volumes and create a new SSD volume with the required size class.
- Attach the volume to the target VM and confirm attachment status.
- Log in to the VM, partition and format the device, then mount it persistently.
- When needed, extend the volume capacity from the console.
- Grow the filesystem inside the guest operating system to use new space.
Validation and operator checks
After deployment, verify connectivity, security boundaries, and backup posture before promoting workloads to production.
Operator tips
- • Use dedicated data volumes instead of storing state only on boot disks.
- • Document mount points and labels for repeatable automation.
- • Coordinate filesystem growth steps to prevent application interruption.
