If you want to move the load off of that osd, you can use the primary
affinity knob:
ceph osd primary-affinity osd.<id> 0
It shifts "primaryness" away from overloaded osds and as such may
affect all pgs for which osd<id> is primary. Trying to change the
primary of a single pg is probably not a good idea. What is your use
case?
Thanks,
Ilya
