 ===== Mountpoints =====
-By default openSuSE will set some conservative mountoptions, that are save, but not best choice for homeoffice use and maybe could also improve company servers. Here are some proposals to think about chenging mount Options.

 ==== 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.
+=== Useful Commands ===
+The KDE- Partitionmanager is still not perfect. LVM is mor powerful in these things:
+== Moving logical Volumes to physical Devices ==
+Usually Partitions or Devices are only assigned to Volume-Groups (VG) and Logical Volumes (LV) are using them dynamically as needed. This makes it sometimes hard to understand, where the Data really is located right now. Especially when you are having different physical Devices, you may want one LV to use one Device.
+For an overview how the Data is split, you can use:
+<code>
+# lvs -o+devices
+LV     VG     Attr       LSize   Pool Origin Data%  Meta%  Move Log Cpy%Sync Convert Devices
+  home   system -wi-ao----  78.63g                                                     /dev/sdb2(8013)
+  root   system -wi-ao----  97.89g                                                     /dev/sda4(0)
+  shared system -wi-ao---- 786.64g                                                     /dev/sdb2(130893)
+</code>
+You can also move them to single Devices if needed. Here i wanted my home to also be on the faster Device sda. As sda4 had enough free space, i could do:
+<code>
+# pvmove -n system/home /dev/sdb2 /dev/sda4
+</code>
