Re: leader none, with only one replicat end no ISR

Hi Adrien,

What happens when you try running the preferred replica leader election
script? Does this restore leadership for those partitions you listed?

Re: leader none, with only one replicat end no ISR

Hello Adrien

Could you give more details about your topic configurations (how many
partitions, what is the replication factor ?)

Usually, partition operations are performed by a broker that has been
assigned as the "controller". You should be able to check the controller
broker id with this command
> echo "get /controller" | ./zookeeper-shell.sh ctl1.edeal.online:2181

Make sure the controller is alive and properly connected to the rest of the
cluster, and maybe take a look in the controller log. Also as suggested by
Harper, give a try to reassign the partitions

Best
