Wol, I'm trying to understand what you and others are suggesting is causing this grub warning. according to the raid.wiki you referenced the last line of grub.cnf should look like this to support booting from RAID: initrd /boot/initramfs-genkernel-x86_64-4.4.6-gentoo In addition, the wiki says " you will need to configure your distro to use an initramfs. here are the last few lines of my grub.cnf: echo 'Loading Linux 4.4.0-36-generic ...' linux /vmlinuz-4.4.0-36-generic root=UUID=cddffa50-9713-4205-aab6-86745735958b ro recovery nomodeset echo 'Loading initial ramdisk ...' initrd /initrd.img-4.4.0-36-generic should I be concerned my grub.cnf uses initrd.img and not initramfs? My grub.cnf was last modified 11/2016 and I've rebooted successfully into a RAID1 since. Finally, on Friday 3/3 I swapped one of the disks (sdc) in this RAID1 with a brand new identical disk. After creating the partitions and syncing I issued install-grub /dev/sdc and there were no warnings. If my grub was broken why would there be no warning but a week ago doing the exact disk swap/same sequence of commands I got a warning. Nothing on the system was changed during that time.
