Dong Lin commented on KAFKA-6188:
---------------------------------
Kafka currently handles disk failure on a per-disk basis, i.e. if there is
IOException when accessing a given partition on a given disk, the entire disk
is marked as offline which in turn marks all partitions in that disk as offline.
Thus, if all disks are marked as offline, all partitions in the broker will be
offline, there is nothing for broker to do and the broker will shutdown itself.
The question here is why there is IOException in the first place. Does it
indicate legitimate issue with the disk, i.e. disk is problematic and should be
replaced, or does it indicate a bug in Kafka (e.g. broker try to access a file
after the fail has been deleted).

> Key: KAFKA-6188
> URL: https://issues.apache.org/jira/browse/KAFKA-6188
> Project: Kafka
> Issue Type: Bug
> Components: clients, log
> Affects Versions: 1.0.0, 1.0.1
> Environment: Windows 10
> Reporter: Valentina Baljak
> Priority: Blocker
> Labels: windows
> Attachments: kafka_2.10-0.10.2.1.zip, output.txt

>
> Just started with version 1.0.0 after a 4-5 months of using 0.10.2.1. The
> test environment is very simple, with only one producer and one consumer.
> Initially, everything started fine, stand alone tests worked as expected.
> However, running my code, Kafka clients fail after approximately 10 minutes.
> Kafka won't start after that and it fails with the same error.
> Deleting logs helps to start again, and the same problem occurs.
> Here is the error traceback:
