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

drbdadm is more simple than drbdstatus.
But, when the old_primary comes back is status is WFConnection 
Secondary/Unknown
and the actual primary becomes StandAlone Primary/Unknown.
On the actual primary: TWICE drbdadm connect XXX ===> the two nodes are 
synchronized.
Whith my configuration I do not need drbdadm connect XXX on the old_primary.

Do you think StandAlone Primary/Unknown is a normal situation ?
What do you think about all error messages I found ?

 Best regards
