2019-02-28T14:20:46.627 ERROR:tasks.deepsea.orch:orchestration ceph.stage.3 failed. Here comes journalctl!

The last item in the zypper log is the output from the '/usr/bin/zypper' '--non-interactive' '--no-refresh' 'install' '--auto-agree-with-licenses' '--name' 'ceph' command which is run by ceph.packages. The last thing this command does is run the %posttrans script for lvm2, which runs dracut to generate a new initrd. Not sure if this is relevant.

Full logs available at http://10.86.0.53:8081/ubuntu-2019-02-28_14:06:27-suse-ses6---basic-openstack/9963/

Examination of the journalctl output just shows that the zypper install ceph seems to complete but nothing else happens because Stage 3 aborts at that point.

So far I have not seen this failure mode in a non-CLI test.
