shall we add some
to drbd_config.h ?
anyways, think of a 3.8 TB device.
if you want to *esure* that they are binary identical,
for a new setup, it is *much* faster to do a
dd if=/dev/zero of=/dev/lower_level_device bs=1M
on both nodes, then setup drbd, make one node
primary, and create a file system on top of it,
than to have all those 3.8 TB go over the network,
even though the don't contain any information.
so I don't think to enforce an initial sync is that brilliant...
