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
$ sudo blkid
/dev/vda1: UUID="51ba13e7-398b-45f3-b5f3-fdfbe556f62c" TYPE="ext4" PARTUUID="000132ff-01"
/dev/vdb1: UUID="2e4a9012-bf0e-41ef-bf9a-fbf350803ac5" TYPE="ext4" PARTUUID="95c4adcc-01"
- Add your disk in the
/etc/fstabfile:
$ sudo vim /etc/fstab
/etc/fstab: static file system information.
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
UUID=51ba13e7-398b-45f3-b5f3-fdfbe556f62c / ext4 defaults 0 0
UUID=2e4a9012-bf0e-41ef-bf9a-fbf350803ac5 /mnt ext4 nofail 0 0
From an instance on Windows
- Access the disk management tool
- Format the disk
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.
