Well, while booting, you do not yet know which node has the good data. So using DRBD below a file system you need to boot the box ("/boot", "/", ...) is not posible without further tweaks, and not really useful anyways. There are different tools for different tasks. How often do you expect the content of /boot to change? See? And why would you want to mirror its "frequent changes" over to the other box in real time then? > Is there a way around this? Have the modules you need to boot the box in the initrd. Lars Ellenberg
