***************************************************************
 DRBD's startup script waits for the peer node(s) to appear.
 - If this node was already a degraded cluster before the
   reboot, the timeout is 0 seconds. [degr-wfc-timeout]
 - If the peer was available before the reboot, the timeout
   is 0 seconds. [wfc-timeout]
   (These values are for resource 'iscsi1'; 0 sec -> wait forever)
 To abort waiting enter 'yes' [  66]:
