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?

I use Lemmy.world, but my homepage (subscribed - hot) is the same as 2 days ago. Also I see a Selfhosted community with about 7K users there, I've tried to search it here (selecting all, not local), I see the [email protected] but it shows only 300 users and the posts there are from a week ago. Is there any problem or am I doing something wrong? Thanks!
