How do I see the resync speed?
You don't.
You can try to "derive" it from what is shown in
drbdsetup status --verbose --statistics
Or mount debugfs, and find some information there.
No, that is not supposed to exist,
and may change at any time, and will not be documented,
so don't rely on anything you may find there.
