Default installation fails

[Stuart Bishop]

Trying to build a simple Swift installation to run some tests against:

juju deploy swift-storage
juju deploy swift-proxy
juju add-relation swift-storage swift-proxy

The swift-storage service gets setup, but the swift-proxy swift-storage-relation-changed hooks fails with an exception:

Traceback (most recent call last):
  File "/var/lib/juju/agents/unit-swift-proxy-0/charm/hooks/swift-storage-relation-changed", line 255, in <module>
    utils.do_hooks(hooks)
  File "/var/lib/juju/agents/unit-swift-proxy-0/charm/hooks/lib/utils.py", line 28, in do_hooks
    hook_func()
  File "/var/lib/juju/agents/unit-swift-proxy-0/charm/hooks/swift-storage-relation-changed", line 153, in storage_changed
    devs = utils.relation_get('device').split(':')
AttributeError: 'NoneType' object has no attribute 'split'

Hi Stuart. The error message could be better, but I'm pretty sure this is because you haven't defined a device (I hit the same error recently).

That is, if you do:

{{{
cat >swift.cfg <<END
swift-proxy:
    zone-assignment: auto
    replicas: 3
swift-storage:
    zone: 1
    block-device: /etc/swift/storagedev1.img|2G
END
juju deploy --config=swift.cfg swift-proxy
juju deploy --config=swift.cfg swift-storage
juju add-relation swift-proxy swift-storage
juju add-unit --num-units 2 switf-storage
}}}

things should work.
