hi steve, I saw your configuration, and through calculation, I feel it cannot handle 40 billion files. rgw_max_objs_per_shard * rgw_max_dynamic_shards = 6552100000 6552100000/10000/10000 = 6.5521 billion _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
