I have two disks - /dev/sda and /dev/sdb in software raid (mdadm).
> efibootmgr: EFI variables are not supported on this system. Do you have efivarfs mounted? openrc and systemd should do this automatically if your kernel has it enabled. # grep /var/sys/firmware/efi/efivars /proc/self/mounts
(In reply to Mike Gilbert from comment #2) > # grep /var/sys/firmware/efi/efivars /proc/self/mounts Sorry that should be: # grep /sys/firmware/efi/efivars /proc/self/mounts
Also, where is your EFI system partition mounted?
Hello Mike, 1) I don't see efivars mounted. 2) Since this was my first efi install, it's not installed the best way. The whole /boot is under raid (/dev/sda1 and /dev/sdb1) as a vfat filesystem. This machine was installed like a year ago, it worked back then, seems like a combination of grub/efibootmgr somewhat got broken because grub does not pull in the "-d" parameter to efibootmgr (--disk). Seems like: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1466150
Can you attach a debug log? You can generate it like this: grub2-install --target=x86_64-efi --debug > grub-install.log 2>&1 I suspect you will need to ask grub upstream for help on this, but I can take a look at the log anyway.
Created attachment 420296 [details] grub.log.xz Output of: grub2-install --target=x86_64-efi --efi-directory=/boot/efi --debug /dev/sda
(In reply to Tomáš Mózes from comment #7) > grub2-install --target=x86_64-efi --efi-directory=/boot/efi --debug /dev/sda Just FYI, the "/dev/sda" on the end of your command line does not mean anything when calling grub2-install --target=x86_64-efi. You can drop that and you will get the same result.
Anyway, yes, it seems like mdraid is confusing grub2-install here. You will need to seek help upstream.
Thanks Mike for the help, will try upstream.
