-----------------------------------
    Status: Patch Available  (was: Open)

>          Components: Configuration

> Currently, if [{{disk_failure_policy}}|https://github.com/apache/cassandra/blob/trunk/conf/cassandra.yaml#L230]
is set to {{stop}} (default), StorageService will shutdown for {{FSError}}, but not {{CorruptSSTableException}}
[DefaultFSErrorHandler.java:40|https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/service/DefaultFSErrorHandler.java#L40].
> But when we use policy: {{die}}, it has different behave, JVM will be killed for both
{{FSError}} and {{CorruptSSTableException}} [JVMStabilityInspector.java:63|https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/utils/JVMStabilityInspector.java#L63]:
> ||{{disk_failure_policy}}|| hit {{FSError}} Exception || hit {{CorruptSSTableException}}
||
> |{{stop}}| (/) stop | (x) not stop |
> |{{die}}| (/) die | (/) die |
> We saw {{CorruptSSTableException}} from time to time in our production, but mostly it's
*not* because of a disk issue. So I would suggest having a separate policy for CorruptSSTable.
