 One possible answer:
 
 	Taken from http://wiki.linux-ha.org/DRBD/HowTo
 
 "[...]
 Note that even though you can do so, it is a bad idea to have 
 the SyncTarget be Primary, it will panic on a network 
 failure, because it then has no more access to good data ...
 [...]"
 
 cs:SyncTarget st:Primary/Secondary              <- 
 
 The syncronisation process didn't finish before your shutdown 
 or had a failure.
