I'm setting up a pair of frontend nodes with a drbd device. The drbd
will have LVM on top and the LVs will be shared out to other systems
(backends) via iSCSI. I'm very new to drbd, although I did play with
it some years ago. In order to make a node the primary, it seems I
need heartbeat (or something else) to manage it? Presumably I can
also add the lvm commands somehwere.

The drbd website recommends pacemaker, which says it is built on
corosync or heartbeat. My question is - this seems like quite a bit
of work for just making sure one node is the primary, is there no
simple approach?

I should add, the applications on the frontends have failover via
round-robin DNS, so no action needed there.
