Charm stuck in "Charm configuration in progress"

charm
1

Hello charmers!

I’m currently writing a charm for our PowerFlex storage systems, the code looks fine and the application and integration with cinder works as expected.

However, after the application got deployed the status get stuck in waiting with a “Charm configuration in progress” although the configuration is complete.

I’m sharing the link to our charm and would appreciate if someone can help me to understand on how to fix it as it can be confusing for the operator. https://github.com/dell-esg/powerflex-cinder-charm/blob/main/src/charm.py

Without knowing how ops-sunbeam works it’s hard to tell. I’d try to figure out who’s setting that status and based on what parameters.

@jproque15130 Seems like you are hitting [1] Can you check if self._stored.is_started is set to True.

[1] https://opendev.org/openstack/charm-ops-openstack/src/commit/54dbb7f0002aff85dde83775838c537120c9498b/ops_openstack/core.py#L202

re what @hemanth-n is saying, you can verify that in three ways:

  • jhack show-stored mycharm/0
  • jhack eval mycharm/0 self._stored._is_started
  • add a print statement to the charm, repack, redeploy

Hello, let me check and get back to you.

[quote=“ppasotti, post:4, topic:15984”] self._stored._is_started [/quote]Hello, not really sure to understand the output:

But never got the prompt back

The other command fails with a permission denied error:

have you connected the ssh plug? snap connections jhack

8

Yes with no effect.

oh wait, is it a reactive or otherwise non-ops charm? if so your only bet is figuring out how to use juju exec to grab the stored state via, presumably, the state-get hook tool?

10

Hi, it looks like the state is currently empty.

ubuntu@juju:~$ juju exec --unit cinder-dell-powerflex/0 -- state-get  --format yaml
{}
11

there is your answer @hemanth-n

I finally succeed to use jhack show-stored by changing permissions on /var/lib/juju/agents/unit-cinder-dell-powerflex-0/charm/.unit-state.db and here’s what I got:
