Hello, First of all: I am new to this Jira and apologize if anything is set or specified incorrectly. Feel free to advise me. We currently have an error in our test system, which unfortunately I can't solve, because I couldn't find anything related to it. No solution could be found via the mailing list either. The error occurs when we want to start up a node. The node runs using Kraft and is both a controller and a broker. The following error message appears at startup: {code:java} kafka | [2024-04-16 06:18:13,707] ERROR Encountered fatal fault: Unhandled error initializing new publishers (org.apache.kafka.server.fault.ProcessTerminatingFaultHandler) kafka | org.apache.kafka.image.writer.UnwritableMetadataException: Metadata has been lost because the following could not be represented in metadata version 3.5-IV2: the directory assignment state of one or more replicas kafka | at org.apache.kafka.image.writer.ImageWriterOptions.handleLoss(ImageWriterOptions.java:94) kafka | at org.apache.kafka.metadata.PartitionRegistration.toRecord(PartitionRegistration.java:391) kafka | at org.apache.kafka.image.TopicImage.write(TopicImage.java:71) kafka | at org.apache.kafka.image.TopicsImage.write(TopicsImage.java:84) kafka | at org.apache.kafka.image.MetadataImage.write(MetadataImage.java:155) kafka | at org.apache.kafka.image.loader.MetadataLoader.initializeNewPublishers(MetadataLoader.java:295) kafka | at org.apache.kafka.image.loader.MetadataLoader.lambda$scheduleInitializeNewPublishers$0(MetadataLoader.java:266) kafka | at org.apache.kafka.queue.KafkaEventQueue$EventContext.run(KafkaEventQueue.java:127) kafka | at org.apache.kafka.queue.KafkaEventQueue$EventHandler.handleEvents(KafkaEventQueue.java:210) kafka | at org.apache.kafka.queue.KafkaEventQueue$EventHandler.run(KafkaEventQueue.java:181) kafka | at java.base/java.lang.Thread.run(Thread.java:840) kafka exited with code 0 {code} We use Docker to operate the cluster. The error occurred while we were trying to restart a node. All other nodes in the cluster are still running correctly. If you need further information, please let us know.
