Maybe you can format it properly to make it more readable ... also, if you read the log it is fairly self-explanatory what the issue is.

[scholzj]

Sorry ... what do you mean with clear the logs?

[Lakshay1912]

i think you are getting the issue which I mentioned in the discussion

[scholzj]

Your disk is full. You should either increase the size or delete some files from it. And once you fix it you should immediately configure the topics to not run out of disk space again.

[Lakshay1912]

Do you know how to resize the disk ?

[scholzj]

If it is supported by your storage class and your platform, you should be able to just increase the storage size in the Kafka custom resource (but you cannot decrease it back later as that is not supported by Kubernetes).

It seems like the error message you provided indicates that the Kafka broker pod has run out of space on the device where it's trying to write data. This can be caused by various reasons, such as a full disk or a limit on the storage quota.

To resolve this issue, you could try one or more of the following steps:

Check the disk space usage on the device where the Kafka broker is running, and free up some space if possible.

Increase the storage quota for the Kafka broker pod, if applicable.

Check the configuration of the Kafka broker and ensure that the log directories are correctly specified and have sufficient space.

Check if there are any temporary files or logs that can be safely deleted to free up space.

Consider archiving or deleting old data that is no longer needed by your application.

I hope these suggestions help in resolving your issue.
