We are using a single agent elastic bamboo instance with Auto-mount EBS volume everytime option. But, as opposed to the description, it doesn't mounts the EBS volume (the one mounted last time) and creates a fresh EBS from the snapshot.

This makes sense for those using many agents configuration, but, for several developers with a single agent license, the same EBS volume must be used instead on creating a fresh one every time.

I mean that there should be an option for this at least. Currently, I assume the process is as follows:

1) Create a EBS volume from the snapshot (snapshotId is provided in configuration) and get its volumeId.
2) Mount the volumeId to the new instance.

I propose that it should be modified as:
1) Ask for a snapshotId and a EBS volumeId(s) in elastic bamboo instance configuration and keep those in record.
2) Launch a new instance and check if a volumeId provided is valid and not mounted already, and if its free, mount it to the new instance and if none of the volumeId(s) is valid and free, create a new volume from the snapshotId, get newly created volumeId and mount it.
3) Optional: Update the newly created volumeId in record (array) for reuse.

I think the option to reuse the existing EBS volume (the same which was used last time) may be provided easily in the elastic bamboo, at least for those using a single instance and this will be of great help for many customers.

This issue is same as https://studio.atlassian.com/browse/JST-3293 and the one that is irrelevant may be closed.

Thanks & Regards
