My preferred storage setup until now was using RAID-1 software RAID built with mdadm; for a new machine I'm considering setting up a RAID-1 btrfs volume as root, but I have much less experience with btrfs Assuming I'm going to format the root filesystem as: mkfs.btrfs -m raid1 -d raid1 /dev/sda3 /dev/sdb3 how should I configure (file-system...)? this way: (file-system (mount-point "/") (type "btrfs") (device (uuid "4dab5feb-d176-45de-b287-9b0a6e4c01cb"))) with UUID taken from "lsblk -f"? From=20you experience is RAID on brtfs as solid as the one on mdadm? Thanks!
