When you follow that, the order of restart is not important. Maybe even make them both secondary before the reboot to make sure. Otherwise the one that was stopped first will (if its started first) wait for the other one to check whether everything is up-to-date. The easiest would be to just use drbd for what its made for: keeping the resource available even when one component fails or is in maintainance. So juse reboot the secondary, switch over and reboot the other, now secondary machine. Have fun, Arnold -------------- next part -------------- A non-text attachment was scrubbed...
