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

Finally found the solution (thanks to Urban Larsson from Sweden) :

Simply run drbdmanage update-pool as cronjob frequently to keep a trace of thin
allocation ON EVERY NODE (it only updates the running node's free space).

Not really a greate workaround but it might do the job for now.

This opens another question for thin allocation on SyncTarget(s) but that's
another thread.
