BTRFS with 8TB SMR drives

Hi guys, just added a new Seagate Archive 8TB drive to my BTRFS volume and I'm getting a tonne of errors when balancing or scrubbing.

A short smartctl test reports fine, running a long one now. Will also run seatools from a bootable DOS USB while at work today.

Running latest firmware on my 9240-8i which explicitly supports this drive.

I'm finding it very hard to tell if SMR drives are OK with BTRFS currently - anyone chime in?

Thanks, Warren
