Noah,

When running run-standalone.sh the test-ceph-helpers.sh and
ceph_objectstore_tool.py file because health won't go clean.  I am
getting "message": "Module 'crash' has failed: Unknown error."

Is there something wrong with my build tree?  Or am I missing an
external python module?
There's no error when running a normal vstart cluster, and when I try
that test runner I can see its mgr_module_path is pointing at
/usr/local, so I'd guess that's the cause.

Does that test runner have special requirements around how daemons are
run, or could we converge it on using vstart.sh?

John

The run-standalone.sh is a relatively new thing we added to remove some
slower tests from "make check".  You could run this in your own build
tree like this.


cd build

../qa/run-standalone.sh

You can also run a single test:

../qa/run-standalone.sh test-ceph-helpers.sh

Or even a subtest

../qa/run-standalone.sh "test-ceph-helpers.sh test_wait_for_health_ok"


I see you added this code:

      mgr: create always_on class of modules

      support an 'always on' class of ceph-mgr modules. the purpose of an
      always-on module is to behave as built-in / non-optional functionality.
      this is accomplished by treating always-on modules as enabled
      irregardless of the enabled set produced by the manager monitor.
      always-on modules that fail to load are reported as health errors.

      always-on modules are intended to satisfy important dependencies in a
      cluster. as such, the set of always-on modules is specified statically,
      as opposed to a property on the Python class, to enable robust error
      reporting of always on modules that fail to load.

Thanks
