Using local Blockstorage on netcup Linux Server

Introduction

In this tutorial we will show you how to integrate and use additional hard disks under Linux on a netcup server.

Requirements

The tutorial is aimed at users who already have access to their server via SSH. Please make sure that your user has the required authorizations.

You can execute the following command at the beginning of each SSH session: bash sudo -i

Step 1 - Overview of available hard disks

To get an overview of all recognized hard disks, use the command:

fdisk -l

In our example, we have two hard disks: /dev/sda (the system hard disk) and /dev/vda (an additional 50 GiB hard disk).

Step 2 - Create a partition

Use cfdisk to create a partition on the additional disk:

cfdisk /dev/vdb1

Select "dos" in the selection menu for an MBR partition table. Then create a 50 GiB partition as the primary partition.

Step 3 - Format partition

Exit cfdisk and check that the partition has been created:

fdisk -l

Format the partition (in our example as ext4):

mkfs.ext4 /dev/vdb1

Step 4 - Mount the partition

Create a folder for the hard disk (in our example "lbstorage"):

mkdir /lbstorage

Mount the partition in the folder:

mount /dev/vdb1 /lbstorage

Step 5 - Automatic mounting after reboot

Find the UUID of the partition:

blkid /dev/vdb1

Open the /etc/fstab file and add the UUID:

nano /etc/fstab

Add the line at the end of the file (replace the UUID with the correct one):

UUID=your_uuid_here /lbstorage ext4 defaults 0 0

Save the file.

Conclusion

The additional disk is now ready for use and will automatically be mounted after a reboot.
