[DRBD-user] DRBD9 not building on PVE6.1

[Denis]

Thank you for your reply Gianni and all for reading.

I realized that internet on my nodes was limited only to standard ports 
out, then drbd-dkms failed.
I solved my problem opening all ports out.

Sorry for wasting your time, next time I can read better even if I am 
not a developer ;-)
