The initial sync is a full image sync, the rest
is based on the object
sets created. There are several options to control the mirroring, for
example:
rbd_journal_max_concurrent_object_sets
rbd_mirror_concurrent_image_syncs
rbd_mirror_leader_max_missed_heartbeats
and many more. I'm not sure I fully understand what you're asking,
maybe you could rephrase your question?

Hi Eugen,
Thanks for the reply. If rbd-mirror constantly synchronize changes,
what frequency to replay once? I don't find any options I can config.
