Ask HN: Do you use btrfs for anything serious?

People using Qubes OS find btrfs fast and reliable: https://forum.qubes-os.org/t/btrfs-and-qubes-os/6967, https://forum.qubes-os.org/t/ext4-vs-btrfs-performance-on-qu...

Synology uses it in production. At least for some features

I use on mine because the volume of write IO is low, it's a spinning disk, and it's mostly just a backup.

And, of course, because it's their default recommendation.

And I think it has been the default on opensuse for at least several years.

Using it in production on hundreds of machines for several years now. Zero issues so far.

i use it personally, but found reiserfs works better for me on spinning disks - both space and speed. ( lots of small files ) - btrfs, even with compression uses more space

for normal workloads, ext4 is fine for me

I thought reiserfs was abandoned.
