[StarCluster] Addnode SGE problem

[Ron Chen]

Do you have the danp user on node001?

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

Subject: [StarCluster] Addnode SGE problem


Hi all,

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).

Thanks,
Dan

danp at master:~$ cat /etc/hosts
127.0.0.1 localhost

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
10.196.149.155 master
10.226.219.58 node001

And here's what the errors look like:

danp at master:~$ qstat -f
