Install Base

- Install Raid1 with MD package activated and assign mount points
Check wether all volumes get mounted during system boot
to check wether root and swap are mounted, enter:
mount free -m -t
to check mismatching uuid's, enter:
ls -la /dev/disk/by-uuid cat /etc/fstab
to fix, do:
vim /etc/fstab
replace the uuid's found in fstab with the ones found in /dev/disk. Make sure you copy the correct uuid (md0, md1) to the respective entry in fstab.
