@VD15 I considered touching btrfs after a reinstall for my fileserver with 3 disks in soft-raid 5. Turns out btrfs has an issue with parity, so it was back to zfs.
I was tired/drunk AF when I planned and did the reinstall from Deb10 to Arch. Turns out I could just `zpool import -f data` the already existing zpools. Saves me days and days of restores from remote backups.
