I would be interested in finding a way to reliably identify reflink /

Hello,
I am on Debian Jessie with a kernel from backports:
4.6.0-0.bpo.1-amd64
I am also using btrfs-tools 4.4.1-1.1~bpo8+1
When trying to replace a RAID1 drive (with btrfs replace start
-f /dev/sda1 /dev/sdd1), the operation is cancelled after completing
only 5%.
I got this error in the /var/l

I have installed Debian with the following partition on the fi
