This is strange, which version of drbd are you using? Is the device
mounted on the primary when you do this? What does /proc/drbd say? Are
the devices really connected?
I think we'll need some more information about your setup and about
what exactly you do when it hangs.

Are there any kernel messages? Any kernel panic?

Well, I've never run drbd on a Mosix kernel, but it would be nice to
hear your experiences.
I'm waiting for more information.
