that's an impressive cross-posting list. Somehow, I'm less than
impressed, though.

Have you created test scenarios in which an unconnected peer is stressed
to the same extent where you usually see crashes?

If not, I call "not DRBD related" on this one. It doesn't seem to make
any sense.

Other than that, you really want to pass up on those backport packages
and create your own, with a DRBD version that's not over a year old.

Another note: The fact that you can rebuild an array using a given disk
is no guarantee that said disk is not broken.
