Responding to your doubt, / is a LVM logical volume on an MD device. But as in this case the boot process was interrupted in the instance where GRUB was in control and not the kernel (because of the "grub rescue" prompt), I thought the problem could come maybe from the side of GRUB. Thanks for your interest. Kind regards, Daniel
