I suggest that you modify drbdadm so that one can specify multiple on sections in a resource section. As the driver and drbdsetup are two nodes only, one will then have to select a peer node when calling drbdadm connect. So the command line syntax of drbdadm will have to change as well. Maybe drbdadm --to foo-node connect r0 Phil -- : Dipl-Ing Philipp Reisner Tel +43-1-8178292-50 : : LINBIT Information Technologies GmbH Fax +43-1-8178292-82 : : Vivenotgasse 48, 1120 Vienna, Austria http://www.linbit.com :
