excuse me when I wonder, based on personal prejudice,
why would someone use Gentoo (effectively a very moving target) for a
High Available Deployment (where you want to be as stable as possible).

in drbd 0.7, there are still some "WE ARE LOST ... panic()".
in drbd 8, we try to do best effort, but if there is no more good data,
we just return io errors to the upper layers.

nonetheless, this is broken hardware.  so, I suggest you look out for
hardware io errors on your disks.
there is not much drbd can do about them.

so you try to setup an "HA-Cluster"
with an unstable OS
and broken hardware.
not a particular good idea :)

at least use some sort of RAID,
md raid1, hw raid...
and monitor your disks (smart, ...).
