Hi Angelo, From my experience, I guess the objects written to degraded pg is immediately degraded. As the total number of objects is increasing, I think the increase of degraded objects is normal. Weiwen Hu

Hey guys,
I'm trying to understand what is happening in my cluster, I see the number of degraded objects increasing, while all OSD's are still up and running.
Can someone explain what's happening? I would expect the number of misplaced objects to increase when ceph's balancing algorithm decides blocks should be on different OSDs, but I would only expect the degraded objects to increase when OSD's die??
