Basically MDS will not let clients in until it was able to connect to at least to one
So if you start your client at a time when MDS just started up and did not connct to an
OST yet, you'll get this error.

Thanks for your quick response !
I created MGS, MDT and two OSTs before I started lustre service on both computer - is it

Yup, that's what you get if you don't have any OSTs.
