You can use the find command on grub prompt to find the grub/boot loader location.

Please refer following links:

Is the RAID array hardware or software based, as in did you create it from a BIOS utility or did you create it from the Linux installer?

If the latter see:  https://wiki.archlinux.org/index.php/Software_RAID_and_LVM
If the former see: http://askubuntu.com/questions/43036/how-do-i-install-grub-on-a-raid-system-installation

grub in generally locates in the root partition. If you look in /etc/grub.conf you can find out where it is. For example -
title Red Hat Enterprise Linux Server (2.6.32-279.1.1.el6.x86_64)
        root (hd0,0)
        kernel /vmlinuz-2.6.32-279.1.1.el6.x86_64 ro root=/dev/mapper/vg_001-lv_root rd_LVM_LV=vg_001/lv_root rd_LVM_LV=vg_001/lv_swap rd_NO_LUKS rd_NO_MD rd_NO_DM LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYBOARDTYPE=pc KEYTABLE=us crashkernel=auto vga=791 3
        initrd /initramfs-2.6.32-279.1.1.el6.x86_64.img

grub is always on boot partition so check the /boot partition details, if it is LV then you can use #lvdisplay -m
