Taruisi, Thanks for that.
I can't believe it was something as simple as that. It's a laptop, so normally I suspend, But yeah, I've tried rebooting since (actually before your message - but thanks anyway), and it's all good now. Seriously gave me a bit of a shock there. Yes, I know, btrfs isn't stable, but I nearly thought it all went like that, poof *touch wood* =). I guess I wasn't used to it not re-mounting after that after an unplug event. Do you know if there's a timeline for device file renaming? I suppose it's not that big a deal now that I'm aware it's not supported. Thanks again for your advice.
