btrfs replace “ERROR: target device smaller than source device”
Why am I seeing:
btrfs replace "ERROR: target device smaller than source device"
when I have already shrunk the source device filesystem to be smaller than the target via:
btrfs filesystem resize <devid>:<small-size> /mountpoint
linux btrfs

The error message is referring to the Linux block device sizes, not the filesystem size, so the partition containing the source filesystem will need to be shrunk to be smaller than (or the same size as) the target.
Assuming the target device is 200G, resize the source device to 199G:
btrfs filesystem resize <devid>:199g /mountpoint
Then resize the partition to also be 199GiB. I used gdisk to remove the existing source partition, then created a new one with the same start sector but entered the end sector size as +199G.
After a partprobe /dev/hdd-device to reload the new partition, the replace worked fine.
