We recently lost power in our lab and had a hard shutdown on our identity manager cluster. When powering up, both ID manager servers get stuck during POST at rabbitmq starting. Any ideas how to fix this?
If all cluster nodes stop in a simultaneous and uncontrolled manner (for example with a power cut) you can be left with a situation in which all nodes think that some other node stopped after them. In this case you can use the force_boot command on one node to make it bootable again - consult the rabbitmqctlmanpage for more information.
