On a server I'm trying to install Debian Bookworm with software RAID1 with three disks. I'm following this guide. Three disks have been configured to use RAID and I've setup the RAID1 device as in the screenshot and a Volume Group. Then I added three partitions, one ext4, one for EFI (that's the ESP partition) and a swap partition.
This all goes great until the installer wants to install Grub and there is a fatal error.
I've also tried without the LVM but that didn't work either.
What am I doing wrong?
