Nope, not planning to attend that. Didn't even know about it.

I'm not energetic enough to plan this right now but will try and go if
someone does.

I don't know to provide any output as I don't know how to access the

stuff. My data came from gparted that showed /dev/sdb as being almost
empty. Maybe gparted can't scan a mirror.
