direct links of old sources may well be a few messages off.

And the following one-liner will give you the maximum device number in
use, handy for automating the addition of new resources:

drbdadm dump | awk
'BEGIN{max=-1}/\/dev\/drbd/{n=substr($2,10,length($2)-10);if (n>max)
max=n;}END{print max}'
