raghavendrat 46a16f1d61 3PAR: Add Peer Persistence support Background: Given 3PAR backend configured with replication setup, currently only Active/Passive replication is supported by 3PAR in OpenStack. When failover happens, nova does not support volume force-detach (from dead primary backend) / re-attach to secondary backend. Storage engineer's manual intervention is required. Proposed Solution: Given a system with Peer Persistence configured and replicated volume is created. When this volume is attached to an instance, vlun would be created automatically in secondary backend, in addition to primary backend. So that when a failover happens, it is seamless. This solution would apply under following conditions: 1] multipath is enabled 2] replication mode is set as "sync" 3] quorum witness is configured Closes bug: #1839140 Change-Id: I2d0342adace69314bd159d3d6415a87ff29db562		2019-09-12 02:26:30 -07:00

Cinder Development Docs

Files under this directory tree are used for generating the documentation for the Cinder source code.

Tools

Sphinx: The Python Sphinx package is used to generate the documentation output. Information on Sphinx, including formatting information for RST source files, can be found in the Sphinx online documentation.
Graphviz: Some of the diagrams are generated using the dot language from Graphviz. See the Graphviz documentation for Graphviz and dot language usage information.

Doc builds are performed using tox with the docs target:
