Hi,
I ran into this problem with 4.1.0-7. The ofi BTL was disabled, but not
the ofi MTL. In some cases, both need to be disabled.
You need something like:
mtl = ^ofi
in addition to:
btl = ^ofi
(I ran into this with https://github.com/LLNL/mpiGraph
red, and you may need to re-add them.
Bug reopened
No longer marked as fixed in versions openmpi/4.1.0-7.

What are the contents of /etc/openmpi/openmpi-mca-params.conf on the

We need to reopen this bug unfortunately. The libfabric
(RDMAV_FORK_SAFE) issue is still live in python MPI applications.
You can see it in pytest-mpi tests as reported previously,
or in a rebuild of mpi4py,

There's evidence this libfabric bug is not fully fixed.
pytest-mpi (0.4-3) is failing tests:
