EBS volume clean up

[t5unamie]

When I restart my machine in opsworks. (Shutdown and then start up)

It reruns the elasticsearch:ebs cookbook and recreates the volume even thow it had already existed.

Is this intended behaviour? I can't see any check to confirm if the volume exists with in the code to simply remount it or attach it if it exists.

https://github.com/elasticsearch/cookbook-elasticsearch/blob/master/libraries/create_ebs.rb

Or am I just blind?

Also, when I set "delete_on_termination" : true, it does not delete the EBS volume when I delete the instance from the opsworks console.

I am also confused by the example for the ebs device location given in https://github.com/elasticsearch/cookbook-elasticsearch/blob/master/attributes/data.rb.

Why is the device name stated under bother device and ebs?

from what I have seen if you set it under devices. It will mount it on the Ec2 instance using the code you porovided. However it doesn't format that location. It will only format the location if the elasticsearch recipe is run after the ebs occurs.

The same volume shouldn't be created "twice".

when I set "delete_on_termination" : true, it does not delete the EBS volume when I delete the instance from the opsworks console.

This is a problem in Fog (fog/fog#1737) which I still haven't had time to solve.

Thanks Karmi,

PS. This happens if you don't select EBS backed instances. As the code checd if the dev location exists on the local system. Which it won't if it's not EBS backed.

Would it be wise to change the check to a tag search and reattach the same one if the EBS is not mounted?

Hello! We've re-written the cookbook from the ground up, and we decided it would be better to leave EBS volume creation to the AWS chef cookbook. Please give that one a try and/or report this bug to them, as I don't think we'll be adding the EBS functionality back in. Thank you!
