> Project: Kafka
> Issue Type: Bug

> I am using Kafka {*}3.9.0{*}. When starting a {*}KRaft controller{*}, it
> shows {*}metadata version 3.0-IV1{*}, but when formatting storage, it shows
> {*}version 3.9-IV0{*}. When I try to confirm the version using:
> {{sh kafka-features.sh --bootstrap-controller localhost:9091 describe}}
> it shows {*}finalized KRaft version 0{*}.
> Can anyone help me resolve this issue?
