Configure an additional volume

Preamble

You have probably created a new additional volume, or an additional disk.

This guide will explain how to create an additional disk, and then how to attach it to one of your instances.

Prerequisites

  • An instance
  • An additional volume attached

Disk mount

From an instance on Linux

  • List disks
sudo fdisk -l /dev/vd*

/dev/vda generally corresponds to the disk of your instance, /dev/vdb will thus be the first additional volume. Some operating systems recognize disks using another driver. In this case, they appear as /dev/sd*.

  • Create a partition with parted
sudo parted /dev/vdb
mktable gpt
mkpart primary ext4 512 100%
quit
  • Format the partition
sudo mkfs.ext4 /dev/vdb1
  • Mount the partition
sudo mount /dev/vdb1 /mnt
  • Checking the mount
mount /dev/vdb1

For a persisting disk mount, you will need to change the /etc/fstab file: - Retrieve the block ID - Add your disk in the /etc/fstab file:

From an instance on Windows

  • Access the disk management tool

public-cloud

  • Format the disk

public-cloud

Please note:

If the message “offline” appears (the disk is offline because of policy set by an administrator), you will need to change the disk attributes by right-clicking your disk, and then selecting “Online” and “Initialize” or by using Diskpart:

  • Launch Powershell or the command prompt
  • Checking the strategy followed
  • Change the strategy
  • Applying the strategy on the additional disk
  • Initialize the disk from the disk manager and then format the disk.

Once the disk is formated, you can easily access it from your file explorer.

public-cloud
