Description

While installing lustre-client-tests and lustre-iokit rpms on RHEL 8.0 client, they hit the following dependency issues:

error: Failed dependencies:
	libmpi.so.40()(64bit) is needed by lustre-client-tests-2.12.54-1.el8.x86_64
	python > 2.2 is needed by lustre-iokit-2.12.54-1.el8.x86_64

On RHEL 8.0, openmpi provides "libmpi.so.40()(64bit)(openmpi-x86_64)", not "libmpi.so.40()(64bit)". There are python2 and python3 on RHEL 8.0, no python.

Yes we should still have the lustre-client-tests rpm which has the common binary and scripts,

and 2 additional lustre-client-tests-openmpi and lustre-client-tests-mpich for the mpt tests only, like the example listed in the fedora wiki:

https://fedoraproject.org/wiki/Packaging:MPI

Still we need to make sure changing the specs won't break the build for old distros like CentOS7

[Andreas Dilger]

Does it make sense to split out the MPI tests into a separate RPM, namely lustre-client-tests-openmpi and lustre-client-tests-mpich, but keep the rest of the test binaries/scripts in lustre-client-tests? That avoids increasing the size of the build products. Alternately, we just build one or the other MPI RPMs, but name them appropriately and add the appropriate Requires: line so that it will refuse to install with the wrong packages.

Since very few users beyond autotest will ever install lustre-client-tests-*mpi I don't think we need to spend too much time making this work everywhere.
