In case the lower level device size changed, but some other internal details of the resize did not work out, drbd_determine_dev_size() would try to restore the previous settings, trusting drbd_md_set_sector_offsets() to "do the right thing", but overlooked that this internally may set the meta data base offset based on device size. This could end up with incomplete on-disk meta data layout change, and ultimately lead to data corruption (if the failure was not noticed or ignored by the operator, and other things go wrong as well). Just remember all meta data related offsets/sizes, and on error restore them all.
