Re: [Linux-HA] Resource location on failover

Here is the scenario. 01) There are two nodes in the Active-Passive cluster--Nomen and Rubric. 02) Nomen had a hardware and software failure. 03) Rubric took over the resources as expected. 04) Due to the failures, Nomen's operating system needed to be rebuilt. 05) DRBD was reinstalled
