Apparently there is a major problem with md-raid/lvm in 
kernels between 4.1-4.5 of which Redhat guys simply say 
something between the lines "keep away from it".
I understand, but will say this: with all the policies and 
politics, if/when providing something one should strive to 
make that thing good, if not the best, in many or all 
respects. And in our situation with regards to kernel this 
is not the case, not because anybody's fault, just because 
the kernel is how it is and these versions are not going to 
get any better nor get fixed, as I understand it.
