@ulfi Oh, since I already asked something: In case of RAID1 on two disks, can both have the same UUID so in case of catastrophic failure the device still boots despite one of them (which could've been the "root") being dead?

That would be really neat.

lsblk works fine on all my installations.

According the UUID shouldn't be two with the same one. But if you install on one btrfs, you can later add the second as RAID1. How the second will be used in case the main was defect depends on your boot (EFI/MBR and grub) setup

@Natanox I don't try that, but it is supposed but you boot the raid, no the device. @ulfi

With mdadmin yes, but with btrfs I was not sure. Not checked my setup till now.
