Mind sharing how you got to this situation? Did you restart brokers? did the replicas drop off the ISR one by one or all together? Do you have unclear leader election enabled? What are the errors you are seeing in the logs?
Once none of the partitions are available and lacking any additional information, restarting the controller is probably the best choice, followed by a complete restart of everything... but your cluster really shouldn't get there.
