Logs for mysqld not appearing (4 replies)

I have a very simple cluster of two data nodes, a management node and all three running mysqld. I am getting logs for the data nodes, but none from the MySQL nodes. I looked in the DataDir that I specified in my.cnf and see nothing along the lines of mysqld.log. There appears to be nothing in the DataDir except data. I looked in /var/log/mysql and found logs there, but they are for another install of MySQL on the box that is not in use. The SQL nodes being used in the cluster don't appear to be sending logs to the data directory. Where else could they be? Thanks
