You just said server-1 was Primary?

Anyways, if DRBD is told to become Primary by someone (like the init
script), but cannot become Primary for some reason, it says so in the
kernel logs.  Find the kernel logs from the time frame where you think
DRBD is misbehaving, and see if it complains about anything.

Or maybe the init script did not even get that far as to try and promote
whatever is configured?
