Native disk scanning is now both reduced and async/parallel, which makes it comparable in performance (and often faster) when compared to lvm using lvmetad. Autoactivation now uses local temp files to record online PVs, and no longer requires lvmetad. There should be no apparent command-level change in behavior.
