Enlarge hard disk

For our managed servers, we provide a simple and flexible option for enlarging the associated hard disks. All server hard disks can be enlarged online and without downtime.


Requirements

  • For a storage upgrade, a full backup must exist for less than 3 hours
  • Storage upgrades can be carried out up to a maximum of 5 TiB via our customer center
  • Your user account must have the authorization to enlarge a hard disk


Attention: Please note that hard disks with an MBR partition table may be a maximum of 2 TiB in size. If you want to increase the size above this limit, make sure that the hard disk has been formatted with a GPT partition table.



Perform storage upgrade

First log in to our customer center at account.creoline.com and select the server for which you want to perform the storage upgrade.


Storage Ansicht - Server


Then navigate to the Storage tab and select the "Expand" button next to the desired hard disk.



You can use the slider to determine the new capacity of the hard disk. Please note that it is not possible to reduce the size of the hard disk at a later date for technical reasons. Then check the contract adjustment preview to determine the new monthly price for your server. You can then carry out the chargeable order using the Increase hard disk button. The storage upgrade will then be carried out immediately and billed from the next contract period. You will receive a separate e-mail with the order confirmation.


The storage upgrade can be carried out in real time and without downtime.



Activate automatic magnification

In addition to manual enlargement of the hard disk, you can also activate automatic enlargement of the hard disk for Linux-based servers based on a defined condition.



Navigate via the sidebar to Server → Your server → Hard disks and select the Auto-enlarge button for the desired hard disk.



Select the desired file system which is to be automatically enlarged in the future. By specifying the condition, you can define from when the automatic hard disk enlargement should be carried out. You can choose between 80%, 85%, 90% and 95%.


By specifying the Capacity, you can set the steps in which the hard disk should be enlarged. You can specify between 10 GiB and 200 GiB here.


You can use the optional Limit capacity to define the maximum limit up to which the hard disk can be automatically enlarged.



The automatic enlargement of the hard disk is then displayed under the current file systems.



Enlarge file system

Once the hard disk has been successfully enlarged, the underlying file system must also be enlarged in the next step if the associated server does not support automatic file system enlargement.


Debian / Ubuntu

To do this, log in to the server via SSH as the root user and enlarge the partition. Replace the device name /dev/sda and the index of the partition with the name from the storage overview. Here: sda and 1.


apt update && apt install -y cloud-guest-utils

growpart /dev/sda 1

resize2fs /dev/sda1


Device Name - Storage View - Server


After adjusting the partition and the file system, you can use the df -h command to check whether the enlargement of the file system has been successfully completed.



Windows Server 2019 / Windows Server 2022

Log in to your Windows Server via web console or remote desktop protocol and open Disk Management.


Disk Management - Windows Server


Right-click on the existing partition of the disk you want to extend and select the menu item "Extend volume...".



The Extend Volume Wizard will guide you through the process of extending the partition. In the second step, you can select the size to be extended. By default, the maximum possible size is already preselected here, so you can confirm this step with the Next button.



After completing the wizard, the enlarged partition is automatically displayed in the corresponding data carrier.



You can exit disk management last and use the new storage space immediately.
