Hi Chris,
I get it now. Thanks. I see it's not that straightforward at this point :(
I guess I'll continue to use ext4 but now I'll consider it over mdadm
(RAID 1) for my next setup as suggested. I'll miss the self-healing
properties of a BTRFS RAID-1 setup but don't want the hassle at this
point when ext4 has served me well.
You don't have those issues with Btrfs on mdadm raid1. You'll still
get metadata self-healing from DUP metadata profile, and you'll get
error detection for data. That's not something mdadm does on its own.
