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

A DRBD device in secondary mode will not be accessible in anyway.   IIRC,
the /dev/drbdX device won't even exist at this point.  If you're using
protocol C and have the DRBD resource on top of LV, you can still snapshot
it and the snapshot should be consistent for a point-in-time.
