Hi Howard
Thanks for your answer.
With disable-verbs, the error message disappears.
Now Vasp is working, it seems the problem was vasp process on the second
node used default LD_LIBRARY_PATH and not the one used for mpirun.

Hi Boyrie,
The warning message is coming from the older ibverbs component of the Open MPI
4.0/4.1 releases.
You can make this message using several ways. One at configure time is to add
--disable-verbs
to the configure options.
At runtime you can set
export OMPI_MCA_btl=^openib
