Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

DRBD will only allow write access to the Primary node. By default, the
cluster comes up as Secondary/Inconsistent just to be safe. To change
that, use this command:

        # drbdadm -- --do-what-I-say primary r0

That is, of course, a dangerous command and you should only do it if
you're certain that the data on that disk is really what you want. In
your case that's pretty easy.
