Update pre-install hooks to fail on error 
The pre-install operations may fail, yet that failure is not
elevated to the user. This masks the failure and makes early
package install issues difficult to troubleshoot.

If the basic pre-install script fails, the charm should not
proceed to later hooks as the requirements may not be met.

Hashbangs for bash should specify -e (errexit) on all of the
pre-install bash scripts.

Ceph Storage Backend for Cinder

Overview

This charm provides a Ceph storage backend for use with the Cinder charm; this allows multiple Ceph storage clusters to be associated with a single Cinder deployment, potentially alongside other storage backends from other vendors.

To use:

juju deploy cinder
juju deploy -n 3 ceph
juju deploy cinder-ceph
juju add-relation cinder-ceph cinder
juju add-relation cinder-ceph ceph

Configuration

The cinder-ceph charm allows the replica count for the Ceph storage pool to be configured. This must be done in advance of relating to the ceph charm:

juju set cinder-ceph ceph-osd-replication-count=3
juju add-relation cinder-ceph ceph

By default, the replica count is set to 2 replicas. Increasing this value increases data resilience at the cost of consuming most real storage in the Ceph cluster.
