So I copied the entire FS back to the SSD using rsync instead of btrfs send/receive and as far as I can tell all the data got over fine. Is there anything you'd like from the subvolumes on the source that btrfs cannot process and that I'm going to delete so that I can start syncing back from the SSD to the HDD?
