I also have this problem having just installed perfsonar 3.3.1.

Was there a solution?


It looks like the problem is that the mesh config

        sudo -u perfsonar /opt/perfsonar_ps/mesh_config
        /bin/generate_configuration

generates
        /opt/perfsonar_ps/perfsonarbuoy_ma/etc/owmesh.conf and this
doesn't contain a variable BWDataDir

The host was completely reinstalled from scratch using the 3.3.1 netinst
iso
