Block Storage

Last updated 30 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.
