Remapped PGs is exactly what to expect after removing (or adding) a
device class. Did you revert the change entirely? It sounds like you
maybe forgot to add the original device class back to the OSD where
you changed it? Maybe share 'ceph osd tree'? Do you have recovery IO
(ceph -s)? Does the number of misplaced objects change?

113 active+clean+remapped
9 active+clean+scrubbing+deep+repair
1 active+clean+scrubbing+deep
I have 113 active+clean+remapped pg's that just stay like that. If I
try to out the this osd to stop it, the clsuter also never settles.
So then if I try to stop it in the GUI is tells me 73 pg's are still
on the OSD...
Can I force those pg's away from the osd?

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?
