Re: Read from Replica Osds?

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.
