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:<div><div><br></div>

Also, you should check the execd's messages file ($SGE_ROOT/default/spool/<host>/messages) to find out why the job caused errors.<br>

Subject: [StarCluster] Addnode SGE problem<br>
<div><div class="h5"><br>
<br>
Hi all,<br>
<br>
I've run into a problem with "addnode" that I'm having a difficult time diagnosing. Using the development version of starcluster, when I issue a starcluster addnode, the nodes added in the resulting cluster are unusable -- they result in SGE errors. Jobs run on the master node, but any nodes I've added are broken. If, however, I start the cluster with multiple nodes then resulting nodes are all usable (so it's not a user code issue). I have a hunch that this is due to the fact that we have several users working under the same account (as different AWS IAM users) and we are not all on the same StarCluster version. To be clear, we are all on varying stages of the developmental version (0.9999). Where do I begin debugging this? The hostfile seems to be set up correctly (see output below).<br>
<br>
Thanks,<br>
Dan<br>
