Kafka Broker down - no space left on device

Hello kafka users,

How to recover a kafka broker from disk full ?

I updated the log retention period to 1 hour from 7 days.. but this would
take effect only when broker is started.

Any ways other than increasing the disk space?

Thanks,
Vignesh

It depends.

You can clean up data folder before starting the broker as long as you have data replicated in other healthy brokers. When you start the broker with clean data folder, it will start catching up with replica leaders and eventually join in-sync replicas.  The catchup traffic impact the overall cluster perf based on the retention time. Since you already reduced retention to 1hour you should be good.
