Need help with creating EBS Volume

[tonyjchong]

Hi, I think I'm missing an attribute but not sure where. Here are my attributes in my elastic search role.

elasticsearch => {
:data => {
            :devices => {
                '/dev/xvda2' => {
                    :file_system => "ext3",
                    :mount_options => "rw,user",
                    :mount_path => "/mnt2/",
                    :format_command => "mkfs.ext3",
                    :fs_check_command => "dumpe2fs",
                    :ebs => {
                        :size => "1024",
                        :delete_on_termination => true,
                        :type => "io1",
                        :device => "/dev/sda2"                  }
                }
            }
        }
    }
}

Then I get this error:

 * ruby_block[Create EBS volume on /dev/xvda2 (size: 1024GB)] action run[2014-06-26T16:02:19+00:00] INFO: Processing ruby_block[Create EBS volume on /dev/xvda2 (size: 1024GB)] action run (elasticsearch::ebs line 16)

Thanks everyone.

[sotzing]

I had the same issue and eventually realized my cloud.aws.region attribute was incorrectly set (to another region). correcting it took care of the problem for me.

[redterror]

@sotzing - thanks for that comment, it helped me.

Perhaps the better thing to do would be to fetch more of the instance metadata and pull the region from there?

You might also try the aws cookbook. It probably has better support for EBS volumes than this one.

[martinb3]

Hello! It sounds like you were able to get this working. In the meantime, we've re-written the cookbook using libraries that expose resources and providers, and we've removed support for the EBS recipe. I would recommend using the AWS chef cookbook for this use case now. Hope this helps.
