Hello, I have seen some installations with following setup: GPT sda1 sdb1 bios_grub md1 0.9 sda2 sdb2 efi md2 0.9 sda3 sdb3 /boot md3 0.9 sda4 sdb4 / md? 1.1
on such installations it's important, that grub installation is made with "grub-install --removable" I mean it was some grub bugs about update grub on such installations, but if you don't blindly update the machine and reboot it shouldn't be the problem. Best Regards, Juri Grabowski
