Dear List,since my update yesterday from 14.2.18 to 14.2.20 i got an unhealthy cluster. As I remember right, it appeared after rebooting the second server. They are 7 missing objects from pgs of a cache pool (pool 3). This pool is now changed writeback to proxy and i'm not able to flush all objects.
