Yes, in glusterd there is no concept of clusterid. It is an id that heketi
creates to refer to a particular cluster.

Nodeid: glusterd generates a node id for all peers in the cluster but the
nodeid in heketi topology info is "local" only to heketi as it has to
create the nodeid before the peer probe command.
