Didn't try it yet, but before everything have been worked with the same
schema, also extending. So, why not this time?

LVM is seeing the metadata on the md device and the "real" nbd device. 

Check that your /etc/lvm/lvm.conf file has the following entry in the

  md_component_detection = 1

If that still doesn't work then you can either disable the nb* devices using
a filter or (which I prefer) only enable /dev/md* devices using the filter.
