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!
For a software RAID like this, you don’t want a hardware RAID controller, per se – you just want a bunch of ports. After my recent controller failure, I decided to try one of these. It’s slick as hell, sitting close to the motherboard, and seems rock solid so far. We’ll see!
