Description of problem: Ceph manager can't load any modules due to a change in cython 0.29. Version-Release number of selected component (if applicable): ceph-mgr-14.2.0-1.fc30 Steps to Reproduce: 1. ceph mgr module enable prometheus Actual results: Error ENOENT: module 'prometheus' reports that it cannot run on the active manager daemon: Interpreter change detected - this module can only be loaded into one interpreter per process. (pass --force to force enablement) Expected results: Enabled module Additional info: This is apparenly a change in cython 0.29 that prevents loading the same module into multiple subinterpreters. I have linked a merged pull request with a workaround in github.
OK, so the Cython in Fedora has been updated, we will need to use the upstream workaround to get this working again, this should be fixed when we rebase to 14.2.1.
