7  2022-05-07 01:01:39 ERROR juju.worker.meterstatus runner.go:91 error running "meter-status-changed": charm missing from disk

I have searched ‘charm missing from disk’ in google, but no answer was got.

What’s the problem and how to resolve it? Who can help me please?

:nauseated_face:

This error is returned when we detect that there is no charm on disk, for which the presence of the charm’s metadata.yaml is a proxy.

The check is made when running a hook, or executing an action.

This looks like an error in charm logic, which has caused the install hook to fail. The error from the meterstatus worker is a symptom of this failure.

4

so how can I deploy “ceph-dashboard” charm successfully? The latest charm " Openstack Charmers Ceph Dashboard" was published at 2011.11.7, and no any updates from then on :joy:

5

is there anybody can give a help?

@billy-olsen can you or someone on your team provide assistance here?

I tested this today and got it to work (Dashboard access) by using the focal series with the below channel (Charmhub) charms. The channel is given in parentheses:

  • ceph-mon (quincy/stable)
  • ceph-osd (quincy/stable)
  • ceph-dashboard (quincy/stable)
  • openstack-loadbalancer (jammy/stable)
  • hacluster (2.4/stable)
  • postgresql (latest/stable)
  • vault (1.7/stable)

These resources summarise my deployment:
