We've been running in production with our small-scale setup for (three?) years now. Mostly problem-free. But... We did have one incident recently with an Ubuntu 14.04 system, which had RAID-1 across 3 drives. Lost one physical drive, and thereby lost the entire btrfs filesystem. Running the btrfs fsck wasn't able to fix it. I likely should have run the latest btrfs-tools to try to fix it, instead of letting the default version that came with 14.04 version try. Still, we're not planning on switching anytime soon. Been using btrfs send/receive for snapshot backups, which is awesome.

I was running 14.04 with its "stock" kernel (can't remember what version, but it was old) and had stability problems after losing a RAID1 drive. Upgrading the kernel made a huge difference in stability, and I was able to recover most of the data.

  It was btrfs RAID-1.

    Actually is well know that BTRFS RAID-1 have problems if degrades to a single hard disk. Perhaps it's related to this.
