Hi folks..

Good news.. I´ve managed to resolve the previous issue with SGEPlugin just
by deleting /opt/sge6 in the AMI base.

Now the problem is the following:

*** WARNING - Cannot find device /dev/xvdz for volume vol-0d8792d3f9ae70b7a
*** WARNING - Not mounting vol-0d8792d3f9ae70b7a on /home
*** WARNING - This usually means there was a problem attaching the EBS
volume to the master node

Starcluster is looking for old names for EBS.. how to manage that in the C5
instance?

All best,

Sergio
