Hello
There is a two-node active/standby shared-nothing DRBD-based pacemaker cluster. The cluster is configured with qdevice on additional host and two-level STONITH/fencing - fence_ipmilan and diskless sbd (hpwdt, /dev/watchdog). All cluster resources are configured to always run together on the same node.
As additional block-level protection, I would like to add a diskless DRBD quorum on the qdevice host.
How to configure diskless DRBD quorum, if DRBD replication links are directly connected without switch ?
