Just a quick note ..
You are correct, it shouldn't be required (v8.9.10) and I was surprised
> with that too.
In the DRBD documentation, it is stated that ...
"When multiple DRBD resources share a single replication/synchronization
network, synchronization with a fixed rate may not be an optimal approach.
So, in DRBD 8.4.0 the variable-rate synchronization was enabled by default."
"In a few, very restricted situations, it might make sense to just use
some fixed synchronization rate. In this case, first of all you need to
turn the dynamic sync rate controller off, by using c-plan-ahead 0;."
..by observing your configuration, it looks like you added that option
since the first time, hence no surprises here, you explicitly decided to
disable variable sync rate ... :)
