I tend to try not to.
If you had mentioned a random package X instead of systemd, my comment would 
have mentioned random package X.

I don't use systemd, but as it's pushed by Redhat and redhat, by default, uses 
LVM, I would expect that part to work correctly together.

lvm-utils?

Ok, to get this straight.
You have x amount of disks
those are in 2 raid-arrays
on top of that, you have LVM...

Can you check that LVM is WAITING for the MDADM arrays to be build?

This sounds like an issue I was having a while ago. I had to add an extra 
dependency to the start-up scripts at the time.

Or enable interactive boot where you can press "I" to have every service ask 
if it needs to be started. Then skip LVM.
Do you have parallel-boot enabled with OpenRC?
If yes, disable that just to make sure that isn't causing the issue with 
OpenRC.
With systemd, I would recommend checking the dependencies between mdadm and 
lvm.
