[StarCluster] Can't restart cluster

[Cedar McKay]

Trying to start a stopped cluster, and I get this and then it stops making progress:

cedar:~ cedar$ sc start -x 55a
StarCluster - (http://star.mit.edu/cluster) (v. 0.95.6)
Software Tools for Academics and Researchers (STAR)
Please submit bug reports to starcluster at mit.edu

>>> Waiting for SSH to come up on all nodes...
No handlers could be found for logger "paramiko.transport"             |   0%  



Any ideas? I’d like to make a new ami from the headnode because I made a lot of changes to the boot disk (nothing related to starcluster) that I’d like to preserve.

Thanks!
