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??
