I would think that there was some initial data movement and that it all went back when you reverted.  I would not expect a mess.

  data:
    volumes: 1/1 healthy
    pools:   7 pools, 1586 pgs
    objects: 5.79M objects, 12 TiB
    usage:   24 TiB used, 26 TiB / 50 TiB avail
    pgs:     4161/11720662 objects misplaced (0.036%)
             1463 active+clean
             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?
