grub error: disk lvid not found

Hello everyone

I'm getting this error at boot:

grub error: disk 'lvid/caoMWu-o417-GMgh-6vFj-1qrw-iJMi-ypwm0f/Z2eotR-N0HN-nrol-3hUd-odMB-GzHy-4PrsnL' not found. Entering rescue mode..

I can't even get the GRUB menu, the error message show immediately up.

Now here's the situation: I had to replace my motherboard because it was broken, and just after the change (I've replaced with an identical one) I'm not able to boot anymore.
Of course before that the system was running fine from at least a year.

This is my setup: Archlinux distro, two hdd, with a RAID1 and LVM builded on top of it. Running on a HP Microserver G8

Below is the LVM setup:

I've already tried to rebuild mkinitcpio and grub-mkconfig but without success. I've also tried to erase MBR and reinstall grub on both sda and sdb

What can I do/check to restore the system ? Any suggestion ?
