Comment 5 for bug 1968621

I'm also seeing this, and together another issue that may be related:

cinder-volume/4 blocked executing 10 10.1.12.62 Services not running that should be: cinder-volume
  cinder-three-par/2 waiting idle 10.1.12.62 Charm configuration in progress

At the same time that cinder-volume complains about not running, the cinder 3par charm does not configure itself. After cinder-volumes are started by hand and I remove/re-add the relation between the 3par driver and cinder-volume, it then happily finishes configuring very quickly.

Unfortunately I can't test if 3par drivers would configure ok on the first try if cinder-volumes were not stopped.
