My mistake. btrfs-replace is for replacing a whole disk as part
of a
BTRFS filesystem. In my case I have a vfat EFI partition, an
ext4 /boot
partition, and a BTRFS root+/home partition, so btrfs-replace
isn't
going to do it.
It's not? I had the same thing and
I just did this recently. I used "btrfs replace", which is part
of
btrfs-progs. See "man btrfs-replace" for details.
It initially refused for one of my partitions (forgot the exact
error
message) but it worked after I ran "btrfs balance".
