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

your changed some metadata config detail. So DRBD hat to detach your
backing device, do the change, then re-attach the backing device. It can
usually do this seemlessly.

The problem is due to the activity log, see

In a nutshell, DRBD is nervous about loosing the freshest of writes to
the primary during a crash, and assumes the peer has more reliable data.
Again: Assuming this while being SyncSource is rather stupid, and I hope
DRBD doesn't do it anymore.

Seeing as you're stuck with the version at hand, you will probably need
to look out for this. I'd be curious as to whether this will go kaboom
with more recent versions as well.
