No, you have a wrong understanding of how DRBD works. It does not store a log of all changes and then runs out of space. It stores a bitmap in memory (and important information on disk in *preallocated* meta data). All in all tiny bits of information are saved *which parts* of the disk changed, but not *what the content was*. You can run a disconnected Primary for ever. So you have a series of "oh part X changed, let me set the corresponding bits for it, oh part X changed again, let me set the same corresponding bits again,..." > I'm not sure and can't find any information related to it.
