Replaced all mdadm RAID1 drives with new, larger drives. Now can not boot from the RAID1

I have simply replaced all of my mdadm array hard drives with some larger drives. I then went to reboot the system and upon booting it comes up with a grub error. I'm not sure what is needed to be done to the mdadm drives to get them to boot properly? I followed all instructions and partitions are all the same, data is all the same, but it still will not boot up properly.

I've attempted to grub2-install, boot into old RAID drives, etc. Nothing has worked. Any ideas?!

Solution 1:

Resolved by changing UUIDs in /etc/fstab for the new drive. Then ran dracut to make sure everything was proper.
