I'm seeing a strange problem with trying to use a Cinder volume for the
elasticsearch PVC when installing logging with Origin 3.7. If I use NFS
or GlusterFS volumes it all works fine. If I try a Cinder volume elastic
search fails to start because of permissions problems:

Refer to the log for complete error details.
The directory ownerships do look very strange. Using Gluster (where it
works) you see this (/elasticsearch/persistent is where the volume is
mounted):
sh-4.2$ cd /elasticsearch/persistent
sh-4.2$ ls -al
