Mudassir Latif 5191751760 Allow replicated volumes to be recoverable
Currently, once they are in ‘error’ or ‘failed-over’ states you can’t
do anything with them. We need to allow enable_replication after the
admin has resolved any issues that may have prevented the operation.

Same thing for after a fail-over, you cannot enable replication on it.

This change allows for more states to be recoverable via enable
replication. It also more uniformly sets the state to ‘error’ when
something bad happens.

'enabled' --> replication is on.
'disabled' --> replication is off by design.
'failed-over' --> we have just failed over. Replication is off.
'error' --> an error occurred during the last operation.

allowed flow is:
'enabled' --> 'failed-over'/'disabled'/'error'
'error' --> 'enabled'/'error'
'disabled' --> 'enabled'/'error'
'failed-over' --> 'enabled'/'error'

Building the docs

Dependencies

Sphinx

You'll need sphinx (the python one) and if you are using the virtualenv you'll need to install it in the virtualenv specifically so that it can load the cinder modules.

pip install Sphinx
Graphviz

Some of the diagrams are generated using the dot language from Graphviz.

sudo apt-get install graphviz

Use make

Just type make:

% make

Look in the Makefile for more targets.

Manually

  1. Generate the code.rst file so that Sphinx will pull in our docstrings:

    % ./generate_autodoc_index.sh > source/code.rst
  2. Run `sphinx_build`:

    % sphinx-build -b html source build/html

Use tox

The easiest way to build the docs and avoid dealing with all dependencies is to let tox prepare a virtualenv and run the build_sphinx target inside the virtualenv:

% cd ..
% tox -e docs

The docs have been built

Check out the build directory to find them. Yay!
