Dear bug triager. This bug was created since a commit was marked with DOCIMPACT.

    Set LVM driver default overprovisioning ratio to 1.0

    This introduces a config option, 'lvm_max_over_subscription_ratio',
    which allows overriding the global max_over_subscription_ratio.

    This is needed because the way we handle configuration with
    multi-backend does not allow setting a value which will be applied
    to each LVM backend without manually setting it in each backend,
    and it would be better to default to a safe overprovisioning
    ratio for the LVM driver. It is often used in smaller deployments
    and POCs which may not have all of the capacity monitoring
    infrastructure used with other drivers, so overprovisioning should
    be an opt-in capability rather than opt-out.

    Partial-Bug: #1472803
    DocImpact: new config option lvm_max_over_subscription_ratio

    [config-ref] Update the cinder tables

    Several patches have landed in cinder and an update is required.

    Note: the cinder.overrides is a temporary workaround for oslo.messaging.
    See https://review.openstack.org/#/c/263818/. This file can be removed
    once a new oslo.messaging release has landed.
