Subject: [Drbd-dev] The drbd resync process

Consider node A crashed as primary and rejoining the cluster,B as the
surviving node.
What's the resync process ?
I can't find how the drbd_start_resync () function call the
w_make_resync_request() to send RSDataRequest message to the SyncSource
When the peer node recovers or the connection is re-established, DRBD
combines the bitmap information from both nodes to determine the total
data set that it must re-synchronize.
Why DRBD needs to combines the bitmap information from both nodes since
one is Primary,the other is Secondary?
Thanks ,I'm just a learner.
