HDD Volumes

Extra block storage for your VM, on our Ceph HDD pool in Lisbon. Made for large data that does not need SSD speed: backups, archives, media, logs, datasets.

At a glance

  • Size: from 100 GB, any size in GB above that
  • Price: €0.56/month for the first 100 GB, then €0.0056 per GB above that
  • Billing: hourly, from your prepaid wallet
  • Location: Portugal (Lisbon) only. A volume can be attached only to a VM in Portugal.

How volumes work

  • Order a volume in the client panel, as an option. Attach, detach and delete it there too.
  • A volume belongs to your account, not to a VM. It keeps existing when you delete or rebuild the VM it was attached to.
  • Attach a volume to one of your VMs and it appears there as a new disk.
  • One VM at a time. To move a volume to another VM, detach it first, then attach it to the other VM.
  • Detach it at any time. The data stays on the volume.
  • Billing runs while the volume exists, attached or not. Delete the volume to stop billing.

Not included in VM backups

Volumes are excluded from your VM's automatic backups, because a volume can be many terabytes. If the data matters, back it up yourself, for example to S3 storage with Restic.

Deleting is irreversible

Deleting a volume destroys its data permanently. We cannot restore it.

First use

A new volume is empty and has no filesystem. Format it once after the first attach.

Linux

lsblk                          # the new disk is usually /dev/sdb
mkfs.ext4 /dev/sdb             # only the first time - this erases the volume
mkdir -p /mnt/data
mount /dev/sdb /mnt/data

To mount it at every boot, add it to /etc/fstab by UUID (see blkid /dev/sdb), with the nofail option so the VM still boots if the volume is detached.

Windows

Open Disk Management, initialize the new disk, then create and format a volume on it.

  • Local disk extension is the fastest. Use it for the operating system, databases and applications. See Large storage/disks.
  • HDD volume is for large data that must look like a normal disk to the VM.
  • S3 is for backups and files your applications read over HTTP. See S3 Overview & Pricing.
