It looks like we're trying to deactivate the volumes when starting the
pool, which is what happens when we can't refresh the pool succesfully.

Deactivation fails, since some of the volumes are still open, and this
overwrites the previous error message.

Try looking in libvirtd.log if there is another error message before
this one.
