Volume management

Volumes are persistent block storage devices that can be created, attached, and detached independently of cloud servers. This page explains how to manage volumes through the Customer Portal.

How to create a volume

1. Log in to the Customer Portal
2. In the left-hand menu, navigate to Cloud Servers → Volumes and select the cloud region
3. Choose a preset volume size or choose the Custom size
4. Select the cloud server to attach the volume to, or choose Do not attach if you want to attach it later
5. Enter the volume name and click Create volume

The volume will be created.

How to mount a volume

1. Before mounting a volume, create a mount point:

sudo mkdir -p /mnt/mount_point_name

2. Before you can use a new volume you need to build a Linux file system on it:

sudo mkfs.ext4 -F /dev/vdb

3. Mount the volume:

sudo mount -o discard,defaults /dev/vdb /mnt/mount_point_name

Keeping mount point through reboots

You need to add a record into the "fstab" config if you want OS to mount a volume automatically after boot:

echo '/dev/vdb /mnt/mount_point_name ext4 defaults,nofail,discard 0 0' | sudo tee -a /etc/fstab

How to attach a volume to a cloud server

Option 1: attach from the volumes page

1. In the left-hand menu, navigate to Cloud Servers → Volumes
2. Select the created volume and click Attach
3. From the dropdown menu, select the cloud server and click Apply

Option 2: attach from the server details page

1. In the left-hand menu, navigate to Cloud Servers → Instances and select the server
2. On the server details page, click Attach volume

The volume will be attached to the cloud server. In the Attached volume row, you will see the path where the volume is mounted on the server.
