How do I change system resources for a server in Oderland Cloud?

Increasing the allocated system resources for a server in Oderland Cloud can affect the cost of the server. On this page you can see the cost of different flavors and disk options.

One of the advantages of Oderland Cloud is that you can easily change which system resources a server has access to. You control this with the so-called flavor the server is set up with and you can change the flavor whenever you want. Sometimes it is even possible to upgrade a server with more memory or more CPU without rebooting.

Change the number of CPU cores and/or amount of RAM

Keep in mind that you may need to restart your server if you change the flavor. Therefore, make sure not to have any unsaved files open on the server.

If your server is set up with hot-plug support, you can upgrade the number of cores and/or available RAM without rebooting, but if your operating system is not configured correctly, you may experience a kernel panic or similar event that forces a reboot.

Sometimes you need more CPU power or more memory on your server and you change these resources as follows:

1. Begin by logging on to the Oderland Cloud control panel.
2. When you’ve logged in, go to Compute (the cube-like icon) -> Virtual machines in the menu to the left.
   
3. If your server is not set up with hot-plug support, you now need to shut down the server before you can change the flavor. Even with hot-plug support, you need to shut down the server if you want to reduce system resources. Do this by first clicking on the row for the server and then on the Shut down button.
   
4. Now scroll down the list below the Shut down button until you see the Flavor row. Click on the pencil icon on that row to access the list where you can select the flavor.
   
5. Select new flavor for your server from the list based on what configuration of CPU cores and RAM you want. Then click the Done button.
   
6. After adjusting the server’s settings (this can take a few minutes, but is usually faster than that), start the server again by clicking the Run button.
   

The server is now starting up with the new system resources.

Increasing the size of a disk

It is only possible to increase the size of a disk, it cannot be decreased! If you are planning a temporary increase in disk space, you can add a new disk instead, which is easy to remove in the end.

Always make sure you have a fresh backup of the contents of your disk before you start expanding your disk space!

Sometimes you need more storage space on an existing disk on a server. To expand a disk in the Oderland Cloud, do the following:

1. Begin by logging on to the Oderland Cloud control panel.
2. When you’ve logged in, go to Compute (the cube-like icon) -> Virtual machines in the menu to the left.
   
3. Click on the row for the server to which the disk you want to extend is attached, scroll down in the right part of the window and click on the disk in the list of attached disks, under Volumes.
   
4. You will now see the properties of the disk. Scroll down until you see Size and click on the pencil to bring up the edit option.
   
5. Enter the new desired size of the disk (which must be larger than it was before, you cannot shrink a disk). Then click the tick mark to save the change.
   
6. The change is now saved. You may need to restart your server for the change to take effect.
