Additional disks

Add, attach, and manage extra disks on supported servers.

What is an additional disk?

An additional disk gives the server extra storage without changing the main plan. The option is shown only for servers whose infrastructure supports extra disks.

Limits

  • Up to 4 additional disks per server.
  • Each disk can be 1–500 GB.
  • The name can use lowercase English letters, numbers, and hyphens, up to 20 characters.
  • The disk is attached to the server and is deleted with the server.

Add a disk when creating a server

In the Create Server screen, open the Additional Volumes section:
  1. Click Add Volume.
  2. Enter a Name and Size (GB).
  3. Choose the Mount Mode:
  • Automatic: mounted at /mnt/<disk-name>.
  • Manual: you run the mount commands after attaching.
  1. Review the monthly cost and create the server.

Attach a disk to an existing server

  1. Open the server.
  2. Select the Volumes tab.
  3. Click Attach Disk.
  4. Choose the Name, Size (GB), and Mount Mode.
  5. Review the cost and click Attach.
If the disk does not appear immediately, restart the server once. For Automatic mount, the server must be online.

Manual mount

If you chose Manual, copy the commands from How to mount. Run them as root:
bash
mkfs.ext4 -F /dev/disk/by-id/virtio-<disk-name>
mkdir -p /mnt/<disk-name>
mount -o discard,defaults /dev/disk/by-id/virtio-<disk-name> /mnt/<disk-name>
To keep the mount after a reboot, add the disk line to /etc/fstab.
mkfs erases the data on the disk. Make sure you selected the correct disk before running it.

Cost

The disk cost is based on its size and is billed monthly. The exact amount is shown in Cost Estimate before attaching.
