Subject [jira] [Commented] (CASSANDRA-2118) Provide failure modes if issues with the underlying filesystem of a node
Date Tue, 14 Aug 2012 22:55:38 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-2118?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13434609#comment-13434609
] 

Jonathan Ellis commented on CASSANDRA-2118:
-------------------------------------------

bq. The enum is there for logging purposes only

I'd say let's just log the exception object and give it a decent toString.

bq. What if there is no longer an issue

Having the operator clear out the blacklist files on restart isn't unreasonable if that's
what he wants.

> CASSANDRA-2116 introduces the ability to detect FS errors. Let's provide a mode in cassandra.yaml
so operators can decide that in the event of failure what to do:
> 1) standard - means continue on all errors (default)
> 2) read - means only stop  gossip/rpc server if 'reads' fail from drive, writes can fail
but not kill gossip/rpc server
> 3) readwrite - means stop gossip/rpc server if any read or write errors.
