Next it is to delete the old BTRFS volume, use fdisk to increase the

Just make sure you have good (tested) backups..
Data subvolumes such as for /home have separate backups but the rootfs
subvolumes do not. If somethings gets screwed up, it is a matter of
reinstalling. Since I run Fedora with anaconda I use kickstart installs
and can easily repeat an install since it included almost everything I
want installed. And then I have a post-install script I run to pickup
additional stuff.
After successfully resizing, I then repeated with a two-device BTRFS
volume. Here the resize needs to be done for each device.
Question: What is did involved two BTRFS volumes on /dev/sdb1 and
/dev/sdb2. I deleted /dev/sdb2 and then expanded/resized /dev/sdb1.
This worked but I assume that doing the opposite would not work. That
is, deleteing the "lower" /dev/sdb1 and then expanding the "upper"
/dev/sdb2 because after rebooting the filesystem would not be at the
beginning of the partition.
