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

There is no drbd daemon. DRBD is an in kernel stacking device driver,
configured through userland tools.
The second configuration attempt was successfull,
the disk was not claimed at that point anymore,
so whatever was accessing sdb1 had a short life.

Likely something triggered through udev (or other) had sdb1 open at that time.
It impossible to determine what had it open at that time, after the fact.
