Joshua McKenzie updated CASSANDRA-10957:
----------------------------------------
Priority: Minor (was: Major)
> Verify disk is readable on FileNotFound Exceptions
> --------------------------------------------------
>
> Key: CASSANDRA-10957
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10957
> Project: Cassandra
> Issue Type: Improvement
> Reporter: T Jake Luciani
> Priority: Minor
>
> In JVMStabilityInspector we only mark ourselves unstable when we get some
> special messages in file not found exceptions.
> {code}
> // Check for file handle exhaustion
> if (t instanceof FileNotFoundException || t instanceof
> SocketException)
> if (t.getMessage().contains("Too many open files"))
> isUnstable = true;
> {code}
> It seems like the OS might also have the same issue of too many open files
> but will instead return "No such file or directory".
> It might make more sense, when we check this exception type, to try to read a
> known-to-exist file to verify the disk is readable.
> This would mean creating a hidden file on startup on each data disk? other
> ideas?
