I can't answer your question because I use Ubuntu and updating the OS is fairly simple. But I did want offer some advice. I also started out having my DRBD nodes mounting their storage over iSCSI. It worked fine but I got significant performance improvements by using local storage instead. In my situation I was able to pull the hard drives out of the NAS and put them directly in the server.
