librbd can optionally read from replicas for snapshots and parent images (i.e. known read-only data). This is controlled via the following configuration options:
rbd_balance_snap_reads rbd_localize_snap_reads rbd_balance_parent_reads rbd_localize_parent_reads Direct users of the librados API can also utilize the LIBRADOS_OPERATION_BALANCE_READS and LIBRADOS_OPERATION_LOCALIZE_READS flags to control this behavior.
