Hello everyone,
My goal is to build a HA DRBD and MYSQL on two nodes(active/passive). I
followed the " cluster from scratch" article to build this environment.
If I do standby failover host, it works fine but when I pull the
heartbeat cable from the active node, the resources do not fail over to
the secondary. Please advise. Thank you very much. Joe
