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.
