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.

For my jbod array, I use ext4 on gpt partitions. Fast efficient mature.

For anything else I use ext4 on lvm thinpools.

That doesn't do error detection and correction nor does it have proper snapshots.

There is error detection, crc checks and lvm does snapshots and offline deduplication

However I run sha256 checks offline and PAR files for forward error correction
