Hi John,
I still think this part in the crushmap is wrong.
step take default
step choose firstn 0 type rack
step chooseleaf firstn 0 type host
step emit
I first take from the defaut -> that's okay,
Now I take two from the rack -> that's still ok
But now, I will take 2 host in each rack, -> that would be 4 locations,
but I have a replication level of 2.
Or don't I understand the placement right?
