Tell me why I shouldn't use btrfs (lemmy.zip)

About a year ago I switched to ZFS for Proxmox so that I wouldn't be running technology preview.

Btrfs gave me no issues for years and I even replaced a dying disk with no issues. I use raid 1 for my Proxmox machines. Anyway I moved to ZFS and it has been a less that ideal experience. The separate kernel modules mean that I can't downgrade the kernel plus the performance on my hardware is abysmal. I get only like 50-100mb/s vs the several hundred I would get with btrfs.

Any reason I shouldn't go back to btrfs? There seems to be a community fear of btrfs eating data or having unexplainable errors. That is sad to hear as btrfs has had lots of time to mature in the last 8 years. I would never have considered it 5-6 years ago but now it seems like a solid choice.

Anyone else pondering or using btrfs? It seems like a solid choice.

Btrfs Raid 5 and raid 6 are unstable and dangerous

Bcachefs is cool but it is way to new and isn't even part of the kernel as of yet.

https://en.wikipedia.org/wiki/Bcachefs it was added as of Linux 6.7

Edit: and I've said raid 5/6 as what troubles btrfs have so you proved my point while trying to explain to me that I'm not right

I though was then removed later as there was a disagreement between Linus and the bcachefs dev

Yeah, i remember something like that, i don't remember exactly which kernel version it was when they removed it

[–] [email protected] 2 points 13 hours ago (1 children)

Pretty sure it's not removed, they just aren't accepting any changes from the developer for the 6.13 cycle
