Well... little warning: after upgrade from 10.2.3 to 10.2.4, I have big load
cpu on osd and mds. Something like that:

On IRC, two another persons have the same behavior after the upgrade.
The cluster is HEALTH OK. I don't see O/I on disk. If I restart daemons, all is
ok but after a few minutes the load cpu starts again.
I have currently no idea about the problem.
