The filesystem we are restoring into needs to be empty and never mounted. Here we check the all of the quorum blocks timestamps to see whether the device we are restoring into has been mounted before. Adds a test in the test script that attempts to restore a previously mounted device. Signed-off-by: Hunter Shaffer <hunter.shaffer@versity.com> Signed-off-by: Auke Kok <auke.kok@versity.com>
