What you need is a colocation constraint combined with an an order constraint, not a place constraint. And the way to do this is documented in the Linux-HA wiki (http://wiki.linux-ha.org/DRBD/HowTov2, see the section "Referencing the master or slave resource in constraints"). Be advised that the wiki page does also talk about a place constraint (in the section "Specifying the nodes where drbd can be run"), but that one is not necessary in 2-node clusters. YMMV. Still, as Lars pointed out, you DON'T use the drbddisk resource agent as a Master/Slave resource, only the drbd OCF RA. Cheers, Florian -- : Florian G.
