[ceph-users] Natutilus - not unmapping

Nautilus cluster is not unmapping ceph 14.2.16 ceph report |grep "osdmap_.*_committed" report 1175349142 "osdmap_first_committed": 285562, "osdmap_last_committed": 304247, we've set osd_map_cache_size = 20000 but its is slowly growing to that difference as well OSD map first committed is not changing for some strange reason Cluster has been around and upgraded since either firefly or jewel I have seen a few other with this problem to no solution to it Any suggestions ? Thanks Joe
