What is Block Storage?
Block storage volumes are persistent, high-performance SSD-backed disks that you can attach to any instance in the same region. Unlike instance root disks, volumes persist independently. See Billing for pricing.
Creating a Volume
Navigate to Storage → Volumes and click Create Volume. Choose the region, set the size (10 GB to 10 TB), and assign to a Project.
Attaching to an Instance
From the volume detail page, click Attach and select your target instance. Format and mount on first use:
Resizing
Volumes can be resized upward without downtime. Extend the filesystem using resize2fs or xfs_growfs. See resize2fs docs.
Snapshots
Take point-in-time snapshots for backup or migration. Snapshot pricing is in Billing.
