[StarCluster] Addnode SGE problem

[Daniel Polhamus]

Thanks Ron, that was helpful.  It looks like the NFS share of my EBS volume
isn't being setup correctly when using addnode.  In my config file, I've
set MOUNT_PATH=/data, yet when I use addnode:

>>> Configuring NFS exports path(s):
/home

Sure enough, if I make changes using the master node in /home/danp, I can
see those changes on node001 whereas there is no /data on node001.

Should I create a bug report for this, or is this message sufficient?
Dan
