Hi, I've tested this PR[1] on pulpito but it seems to fail everytime[2]. I suspect that LD_LIBRARY_PATH and PYTHONPATH are not updated in the test environment to required values before the test begins to run. Usually, while testing locally I run the following commands beforehand - export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/user1/repos/ceph/build/lib/ export PYTHONPATH=$PYTHONPATH:/home/user1/repos/ceph/build/lib/cython_modules/lib.2/:/home/user1/repos/ceph/src/pybind/ The reason why I suspect this is that the error in the teuthology log[3] is very familiar, I've seen it when I used to forget running above commands. Also, the following line in the log must mean that the PYTHONPATH doesn't hold the path to ceph_volume_client.py - ModuleNotFoundError: No module named 'ceph_volume_client' Is there a way to check, and update if required, these variables in environment before the test runs?
