The client should not need to contact the mon for each object access and every client can't have a complete list of millions of objects in the cluster, so it does client-side computations. The mon connection will more or less only require new updates if/when OSDs change weight or goes in/out. This way, clients can run on "autopilot" even if all mons are down, as long as OSD states don't change. -- May the most significant bit of your life be positive. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
