Ceph - 'ceph osd reweight-by-utilization' was used and now cluster is showing PG's stuck unclean with degraded objects

Solution Verified - Updated -


  • 'ceph osd reweight-by-utilization' was used in an attempt to help re-balance data on over-utilized OSD's throughout the cluster. After the data was re-balanced and the cluster settled down, Placement Groups can be seen stuck unclean and remapped with objects in a degraded state.
