Per OP on https://issues.apache.org/jira/browse/CASSANDRA-6298
"
As it turns out, I was using symlinks. I had my last data directory
pointing to the same data directory.

lrwxrwxrwx 1 root root 6 Oct 30 18:37 data01 -> /data1
lrwxrwxrwx 1 root root 6 Oct 30 18:37 data02 -> /data2
lrwxrwxrwx 1 root root 6 Oct 30 18:37 data03 -> /data3
lrwxrwxrwx 1 root root 6 Oct 30 18:37 data04 -> /data4
lrwxrwxrwx 1 root root 6 Oct 30 18:37 data05 -> /data5
lrwxrwxrwx 1 root root 6 Nov 8 18:46 data06 -> /data5

As you can see (not so clearly) the last link data06 is pointing to data5.

Maybe Cassandra can do some basic checking (at startup) to check that the
data directories aren't repeated or pointing to the same location.

In any case, not a bug in the server.
