Dear DRBD-Users!

Is it possible to run Linstor with DRBD Mode B?

Linstore states it will accept "ONLY MODE C"

We have used mode B for ages without any problems. Mode C doubles the
DRBD latency because of the second disk access.

[In our case the network TTL can be neglected since we are using an
Infiniband Network with TTLs wide below the rotational latency of our
spinning disks.]
