Hi,  thanks for your reply.  Now, I have another question. Given all the writes are replicated in order, why is flush event replicated? As far as I know, what a flush does is just making previous writes committed and doesn't do any modification to the data, which makes it seem to me that replicating it or not doesn't make any difference.

Yes -- until it reaches a flush event and is stalled on the


uncommitted IO from the down OSD (or until it reaches the hard-stop of


100 in-flight, uncommitted IOs).
