Whether or not you "snapshot a copy of the secondary over to the new
node", a safe thing to do is to force-create new meta-data on the new
node, and let DRBD do a full sync.
Then you can still take advantage of a snapshot copy by setting
csums-alg : a full read will be done on both nodes but only the
different blocks will be written to the new node.
