Hi all, I've installed Debian in 2 (mdadm RAID 1 formtted with Btrfs) NVMe drives installed into 2 PCIe adapters. The motherboard doesn't support booting from those drives, so I've installed Debian into a USB stick (and it works) and I wanted to add into grub the RAID NVMe drives.
os-prober doesn't see the other Debian installation.
fdisk -l shows the 2 nvme drives, but it doesn't see md0:

mdadm --detail --scan doesn't output anything. How do I solve this problem?
Cool, I've never hear about it, I'll test it first thing on Monday, thanks!
