The ceph command does not complain right now. But I just noticed during the installation that there was an error installing some python packages: > > TEST FAILED: > /home/ssd/src/vanilla-ceph/ceph-install/lib/python2.7/site-packages/ > does NOT support .pth files > error: bad install directory or PYTHONPATH > > You are attempting to install a package to a directory that is not on > PYTHONPATH and which Python does not read ".pth" files from.
