google for drbd ko-count ...
I assume your Secondaries IO-subsystem got stuck.
you should configure ko-count = 6 or so.
it would have started to count ".... ko = 6",
and at "ko = 0" it would have gone StandAlone,
recovering from this situation.
you should also upgrade to a 2.6 kernel,
where this won't lock up the box but only the drbd partition.
2.4 has only _one_ runqueue for _all_ disks, if it gets stuck
on one disk, all io is stuck.
