Just wanted to share some love for this filesystem.
I’ve been running a btrfs raid1 continuously for over ten years, on a motley assortment of near-garbage hard drives of all different shapes and sizes. None of the original drives are still in it, and that server is now on its fourth motherboard. The data has survived it all!
It’s grown to 6 drives now, and most recently survived the runtime failure of a SATA controller card that four of them were attached to. After replacing it, I was stunned to discover that the volume was uncorrupted and didn’t even require repair.
So knock on wood — I’m not trying to tempt fate here. I just want to say thank you to all the devs for their hard work, and add some positive feedback to the heap since btrfs gets way more than it’s fair share of flak, which I personally find to be undeserved. Cheers!
I’ve been using it in Fedora since they switched to it as the default FS. I have not done anything special. I am not trying anything fancy except
compress-force=zstd:1. Seems good to me!Why just :1? The default is :3 and looking at the timings for zstd deflate speed vs compression level (Google for it … ), becomes slow at around 7.
Don’t mean shit to me but suggest you reconsider.
Slow relative to what? Any zstd compression, while really fast, will be slower than native write speeds to my nvme. A tiny bit of ratio gain isn’t worthwhile to me.
