Block Storage

Last updated 2 April 2026

Overview

Block storage volumes are additional disks you can attach to your servers. They provide persistent storage that survives server reboots and can be moved between servers.

Creating a Volume

  1. Go to Volumes in the sidebar
  2. Click Create Volume
  3. Enter a name and select the size (in GB)
  4. Choose the datacenter location
  5. Select a server to attach it to (optional)
  6. Click Create

Attaching and Detaching

  • Volumes can be attached to one server at a time
  • To move a volume, detach it from the current server, then attach it to another
  • Detaching a volume does not delete the data

Using a Volume on Your Server

After attaching, the volume appears as a block device (e.g. /dev/sdb). You need to:

  1. Format the volume (first time only): mkfs.ext4 /dev/sdb
  2. Create a mount point: mkdir /mnt/data
  3. Mount the volume: mount /dev/sdb /mnt/data
  4. Add to /etc/fstab for automatic mounting on reboot

Pricing

Block storage is billed monthly based on the volume size. Volumes are charged whether or not they are attached to a server.
