Deduplication is awesome, it's really unfortunate how dangerous it is with things available on Linux. I've had ZFS corrupt itself twice and not after disabling it, on the same hardware. And btrfs died on me once - I'm not 100% sure it's exactly due to that, but there's a limit how much I'm willing to spend time copying terabytes.

Was the btrfs failure with RAID? Compared to LVM/dmraid with other filesystems on top... BTRFS is remarkably easy to fault.

I can reliably break BTRFS RAID using the reset switch on my system. Others behave fine via journaling and whatever, same devices/kernels/RAID level
