I don't see a 'btrfs filesystem resize' command in your sequence. Did
you actually resize the file system before you resized the underlying
(virtual) block device?



>>> btrfs fi show
>>> Label: none uuid: x
>>>            Total devices 1 FS bytes used 473.68GiB
>>>             devid 1 size 492.00 GiB used 492.00GiB path /dev/sda1

Is this before or after the resize?
