If that is indeed the case I'm afraid I see where Graham is coming from. You could likely make it work by ensuring md was offline on one of the nodes and online on the other anytime you did any maintenance to the md setup. I assume you don't have any way concocted to use a hotspare, but you definitely could not do that sort of thing with this setup. Given that you're talking raid0 from a md perspective, I don't see a lot maintenance anyway so that may be a very livable situation. As to: "You can stack DRBD on top of md, md on top of DRBD is nonsense, however". I still don't know why that is true in a active-passive setup. It seems totally logical to me to stack md raid0 above drbd raid1 in a active-passive setup, but that may be different thread. Greg -- Greg Freemyer The Norcross Group Forensics for the 21st Century
