You technically can but the btrfs implementation is problematic. It has gotten better but it isn’t remotely production ready.
It does support raid1, raid10 and raid1c2/3. The reason I like btrfs is that it is baked into the Linux kernel so I can manage it with the file system utilities. It also runs well on cheap mismatched hardware it I don’t need to spend a fortune on storage.
Doubt
If anything btrfs is a decent replacement for ZFS
Those two aren’t in the same league.
It depends on what you are doing
Database performance on btrfs is miserable compared to zfs, whereas bcachefs was doing much better.
I say was because… see the other comment in the thread. :/
On raid 5/6 ?
