how was your disks partitions? and how was the lvm setup?
was /boot made of a mdadm raid1 array?

there is a dracut issue on raid1 array (fixed by now, if you updated
to the latest dracut release and rebuild your initramfs):

Btw the anaconda installer does install grub on the MBR of both raid1 members.
No idea if it does so for lvm over raid10 array.
