Comment 5 for bug 2024253

I deployed charmed Openstack exactly as described in this manual: https://docs.openstack.org/project-deploy-guide/charm-deployment-guide/zed/install-openstack.html
Just step by step.
My ceph-mon.yaml and ceph-osd.yaml was:
maasadm@maascont:~/openstack$ cat ceph-mon.yaml
ceph-mon:
  expected-osd-count: 4
  monitor-count: 3
maasadm@maascont:~/openstack$ cat ceph-osd.yaml
ceph-osd:
  osd-devices: /dev/sdb /dev/sdc /dev/sdd

And after successful deployment one month ago I tried to upgrade charm simply command 'juju upgrade-charm ceph-mon'
