On a system where: 1) Each disks comprising the array is fully LUKS encrypted 2) Each mapped disk is made part of a Btrfs RAID1 array
When attempting to boot the system after pulling out (in BIOS or using the cable) the drive to simulate a complete disk failure, GRUB hangs, prompting for the LUKS password of the disappeared drive and (unsurprisingly) failing to open it. This prevents booting in a degraded LUKS encrypted, Btrfs RAID1 on Guix System. Maxim
