I'm afraid the error message you're getting is from libibverbs; it's trying to
load a plugin named libsmartio-rdmav17.so. That's not part of Open MPI, sorry.
That likely means that some dependency of libsmartio-rdmav17.so wasn't found,
and the run-time loading of the plugin failed (vs. not being able to find the
libsmartio-rdmav17.so file).
You might want to track down where you got the libsmartio-rdmav17.so file from.
