[ceph-users] The effect of changing an osd's class

I created a new osd class and changed the class of an osd to the new one without taking the osd out and stopping it first.  The new class also has a crush rule and a pool created for it. When I realised my mistake, I reverted to what I had before. However, I suspect that I now have a mess on that osd. What happened when I did this?
