Cannot connect to ec2 instance after rubber automatic reboot

Question

enter code hereI I'm trying to deploy to ec2 a rails 3 app using rubber for my first time. During the run of the command cap rubber:create_staging the instance was asked to do a reboot and then it won't accept a connection. This is how it looks:

The problem is that by running rubber:create or any other rubber command, after the instance is created and initialized, after the /etc/hosts file is written, then I receive a "connection failed" error and everything stops there.

If I do an ssh to the address written in the hosts file, then I am able to connect perfectly to the instance so I don't understand where the problem lies…

Answer 1

make sure from the EBS volume /dev/xvda1 is already attached to the ex2 instance.

Goto EC2 -> Volumes and take a look to the EBS volume that you have. id you see that volume is in the available state try to attach it the ec2 instance and reboot the instance.
