These tools have dedicated jobs, there is no "same thing", if "the
thing" is something a bit more fine grained than "drbd". drbdsetup is
the most low level tool that does all the magic, an admin usually should
not use it directly ("drbdsetup status" is an exceptioin). drbdadm is a
highlevel tool that an admin uses for 99% to do her/his daily tasks.
Previously, that was enough. 2 nodes, you copy the *.res files and
everything is fine. With drbd9 you have a multi-node cluster, which
requires an additional abstraction layer for distributing the cluster
configuration (drbdmanage does a lot more than that).
drbdmanage uses drbdadm which uses drbdsetup, which is fine.
