At synyx we constantly try to improve the quality of the work of the Operations team. We found we were missing certain security requirements. Although we were already using ssh-key-authentication for all our linux-servers, we still had some devices and assets lying around, that were (only) accessible with the vendor-assigned default credentials.

During installation of Proxmox VE 3.3 (available here), you are only given the choice of what disk you want to use for the installation process, but not what disk layout you want to use. Now, there are several ways of installing Proxmox on a software RAID. One of them is to run through the standard installation process and add a software RAID afterwards, using mdadm. This blog post is just to show how setting up a software RAID on a fresh Proxmox installation worked for me!
