i understand that the server should be in an idle state for scrubs and smart tests. what qualifies as idle? i'm running plex and logitech media servers but they probably won't be doing anything when the scrubs and tests are run. i'm also running transmission to seed torrents, so any transmission activity will be mostly disk reads. will that be a problem for the scrubs and smart tests? do i need to disable any of these before running the scrubs and smart tests?
