** Description changed: - If Ubuntu is really committed to ceph as I think I've been reading: - Notice the ceph dashboard went entirely broken in a major regression of - the disco upgrade. It won't load at all in 13.2.4+dfsg1-0ubuntu2. + [Impact] + The ceph-mgr daemon is unable to load additional module due to a new check in cython >= 0.29. This limits the function of the manager. + + + [Test Case] + Deploy ceph + Check /var/log/ceph/ceph-mgr.`hostname`.log + Errors about loading rados module in subprocesses will be seen. + + [Regression Potential] + The fix from upstream actually just works around this issue by overriding the check that cython does; the code works in a subprocess when loaded multiple times. Regression potential low; cython may produce a longer term fix which means we can drop this patch. + + [Original Bug Report] + If Ubuntu is really committed to ceph as I think I've been reading: Notice the ceph dashboard went entirely broken in a major regression of the disco upgrade. It won't load at all in 13.2.4+dfsg1-0ubuntu2. The detail is ceph-mgr (and lots of ceph) relied on a non-feature in cython that went away in cython v29, to do with sub-interpreters. The ceph folks responded with a hack/workaround to avoid the bug being noticed, and a requirement of the package for an earlier version of cython. This was done some weeks and months ago. Actually fixing the problem is a major project the ceph maintainers are struggling to engage, perhaps waiting for later versions of cython to provide a different way forward. However, as of today, on disco ths error message remains: Module 'dashboard' has failed dependency: Interpreter change detected - this module can only be loaded into one interpreter per process. The ceph primary development platform is Debian, on which the workaround has been available for some time. However in our ubuntu case, a major feature of a core packge (web health/monitoring/config interface of a distributed file system), was allowed to both ship broken and remain so for a long time, even through today. I urge quick attention to the necessary backports. https://github.com/ceph/ceph/pull/25585 http://tracker.ceph.com/issues/38788 http://tracker.ceph.com/issues/37472 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1832105 Title: ceph-mgr dashboard incompatible with cython >= 0.29 (disco) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ceph/+bug/1832105/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
