Ian Wienand 2d4295d3ab Replace openstack.org git:// URLs with https://
This is a mechanically generated change to replace openstack.org
git:// URLs with https:// equivalents.

This is in aid of a planned future move of the git hosting
infrastructure to a self-hosted instance of gitea (https://gitea.io),
which does not support the git wire protocol at this stage.

This update should result in no functional change.

drbd-devstack

DRBD installation helper for DevStack.

  • Free software: Apache license

This plugin helps to install the DRBD backend for Cinder (and, later on, Nova) in a devstack install.

Usage

Put some lines similar to these in your `local.conf`:

enable_plugin drbd-devstack https://git.openstack.org/openstack/drbd-devstack CINDER_ENABLED_BACKENDS=drbd:drbdmanage

A few environment variables can be set to modify the behaviour:

  • CINDER_DRBD_NO_STORAGE means --no-storage
  • CINDER_DRBD_NO_CV gets translated to --no-control-volume. This is allowed only for additional nodes, and not the initial drbdmanage node that has to create a control volume.
  • CINDER_DRBD_USE_DRBD_PROTOCOL makes the driver use the DRBD protocol to provide storage to the Nova nodes.

Secondary nodes are detected by having $SERVICE_HOST unequal to $HOST_IP, and therefore register themselves as additional nodes in drbdmanage.
