Performing Manual Split-Brain Recovery
When automatic split-brain recovery is disabled, and split-brain has been detected, the HA status icon on the Overview screen indicates an error on both the active and standby nodes, and a Recover button appears.
Because the data between the two devices are no longer synced after split-brain occurs, you may want to save and compare the data between the two devices, before deciding which device to configure as the active node.
