    `Bug #1432387 <https://bugs.launchpad.net/cinder/+bug/1432387>`_: Try
    to automatically clean up file locks after a resource (volume, snapshot) is
    deleted. This will alleviate the issue of the locks directory always
    increasing the number of files.
Remove file locks once we delete a resource File locks are never removed from the system, so they keep increasing in the locks directory, which can become problematic. In this patch we start trying to delete these lock files when we delete a volume or a snapshot. This affects the 2 type of file locks we currently have: - Using oslo lockutils synchronized with external=True - Using coordination.synchronized when deployed in Active-Passive and no DLM This will alleviate the ever increasing files in the locks directory. Deployment tools should implement a service that runs when the host is booting and cleans of the locks directory before the OpenStack services are started.
