tech question (btrfs) 

i'm reading about btrfs and still struggling to see any reason why i wouldn't just use ext4. there's gotta be a reason, right? i'm just not seeing any, especially if you just want a no-nonsense fs that you don't plan on interacting with all that much. snapshots and subvolumes and all that stuff just looks like a hassle rn

tech question (btrfs) 

@trwnh snapshots and subvolumes are the primary reasons to use btrfs. The other is that it is a CoW filesystem, which is superior to journaling.

tech question (btrfs) 

@matt yeah and i'd really like to understand what those are, why i'd use them, how i'd use them, etc

tech question (btrfs) 

@matt see this is a much better start to my research than the other 20 tabs i have open rn, this is good

@trwnh I use BTRFS for my NAS RAID10 array for the bitrot protection. As long as you avoid RAID5/6 you should be fine.

Though if I were to rebuild the array today I would do it with ZFS

tech question (btrfs) 

@matt i'm pretty wary of zfs's inflexibility with regard to exact disk sizing, so i'd personally not use it unless it was for a fixed deployment. buying drives in batches is just not affordable for me, and it's probably a bit bad for reliability too bc it could lead to multiple failures within a short timeframe. being able to add different-sized drives at any time is pretty important to me

tech question (btrfs) 

@trwnh True, btrfs is definitely flexible in that regard.
