Well Gents,
Its been a rough ride, and a rough couple of days. But the "btrfs check --repair" did the trick, the disk mounted, i rebooted just to make sure everything reloaded ok, and all my data is back, my docker containers are working fine, and all is good with the world.
Thanks heaps for your help, and answering my stupid questions, hopefully your answers can help someone else in a similar boat to me down the line.
I think has reminded me how past due I am for an offsite backup of these config and other important files. Time to investigate a backblaze type of solution.
Thanks again everyone who commented, much appreciated and much Love 💗
