</I>&gt;<i> you want LVM to control.  It lets you create multiple &quot;virtual&quot;
</I>&gt;<i> partitions each of which includes one or more physical partitions.  In
</I>&gt;<i> the minimal case, you can partition exactly as you would without LVM,
</I>&gt;<i> but make each of the Mageia partitions an LV formatted as ext4 (or
</I>&gt;<i> whatever) rather than a physical ext4.
</I>&gt;<i> 
</I>&gt;<i> The difference is that later on if you need to expand one of these 1-1
</I>&gt;<i> LVM partitions, all you do is create another physical partition
</I>&gt;<i> *somewhere* - either on that physical disk or another you add - and tell
</I>&gt;<i> LVM to make that new physical partition part of the LV you want to
</I>&gt;<i> expand.  The original physical partition on which you based the LVM
</I>&gt;<i> stays exactly where it is without change, and the Logical Volume just
</I>&gt;<i> magically increases in size by the size of the new physical partition
</I>&gt;<i> you added.
</I>&gt;<i> 
</I>&gt;<i> Using LVM for some or all of Mageia has no effect on your ability to use
</I>&gt;<i> standard partitioning for other partitions on these disks.

don't forget that a filesystem on top of this, still has to be resized as 
well...
