Re: cannot mount directories at work nodes.

Update: I just tried starCluster AMI : ami-a19e71c8 (x86_64) and got the
same error. :(

The config file automatically generated by StarCluster says the base
x86_64 ami is ami-a5c42dcc. Is this one newer or older than ami-a19e71c8?

Best wishes

Sincerely yours
