Hello Guix!
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 you experience is RAID on brtfs as solid as the one on mdadm?
Thanks!
Gio'.
