Useful for quick binary searches while avoiding the "dput" delay in the PPA. Some problems are only reproducible in the Upstream CI, sadly... Change-Id: I541fedcb7c793fc5b4a1dd28607af7f01fbbfb84
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 git://git.openstack.org/openstack/drbd-devstack enable_service 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.
