Thanks for the info. However I have one more Q:

So my /etc/fstab file has now instead of LABELS devices suck ad 
/dev/md0, /dev/md1 etc...

I've changed the actual devices with LABEL=/, LABEL=/boot, but after a 
reboot I get an error "unable to resolve LABEL=/"

What am I missing here?

Thank you.
