+The important part is metadata=1.0 - this format has especially designed to fit the needs of raid1 of fat/efi- systems.
 ==== LVM ====
 LVM is a powerful partition-management-layer and should always be used, when there is some none low-end hardware present. If you can use the **KDE Partitioning- Tool** (which means having Plasma=KDE Desktop compatible support), the support is very inuitive and opens a lot of flexibility whne handling partitions, like adding more disk space or moving partitions, but also on console this offers good functionality. OpenSuSE offer to create LVM- Styled system setup in installation optionally (not by default). If you can: use it.
+=== Raided LVM- Volumes ===
+Noadays, raid1 or raid5 for system without LVM is outdated. Those things are integrated in LVM - so use it!
+First, creat a volume group with two same size partitions on two discs, than create a raid1 on it (for example):
+<code>
+vgcreate vgsystem /dev/sdX1 /dev/sdY1
+lvcreate -m1 --type raid1 -l 100%FREE -n lvroot vgsystem
+</code>
+where 100%FREE means 100% of Free Space used…
+To check if raid1 works, use:
+<code>
+lvs -a -o name,copy_percent,devices vg_xxx
+</code>
+If this has not worked, use:
+<code>
+lvconvert --type raid1 -m1 vg_xxx/lvol1
+</code>
+Or - you can do raid5 with:
+<code>
+lvcreate -n lvdata --type raid5 -l 100%FREE -i 2 vgdata
+</code>
+where i equals the number of devices with Data (not including parity- storage)

 BTRFs has a lot of Mountoptions and some here are really odd ones for every linux. I would suggest at least those:
-For **Desktopusage**: compress=zstd:1,noatime,nodiratime,autodefrag
+For **Desktopusage**: compress=zstd:3,noatime,nodiratime,autodefrag
 While autodefrag should not be necessary on ssd- harddiscs.
