Build a RAID6 LVM volume, then test failure and replacement of one (or two) of the drives

While learning about different RAID levels and their configurations, I wanted to mess with the RAID abilities of the Linux Logical Volume Manager (LVM), in my case using the Debian lvm2 package in SparkyLinux on a virtual machine setup using VirtualBox.

Long stories short: How I made a "VR" stereoscopic 3D SBS (side-by-side) movie from pictures and videos taken with a Fuji FinePix REAL 3D W3. The article contains more or less reproducible steps, also as a reminder for myself when I try the same thing next time.

Recently I've started a serious professional training course aiming to become a certified "Java Programmer" at ils, a German classic distance learning institution.

I've stumbled upon a marvellous website recently, which is neatly layouted and also animated. On a closer look; they are using WordPress, apparently along with:
