I did some experimentation (spotted a few problems with the deployment) and then decided I wanted to remove the store.
First off I tried to delete the bucket, and was told "You need to delete all versions first": grr! Went and deleted all objects, but this wasn't enough, as versioning was enabled. So, turned version lifespan down to 1 day, and waited 24 hours.
Great, now I could delete the bucket - however, I can't find any option to delete the store. So, I'm stuck with the (in my mind, greedy) VMs the deployment created, as I can't even go behind it's back and do anything with the VMs, as they're "special", just like the hidden Calm project which is used to deploy the store.
All in all, not very impressed on first experiences...

The list of known issues, however, mentions “You will not be able to delete the primary object store (first object store created) as it hosts the IAM service.” If you were attempting to delete the primary object store then that would explain why Support had to do some magic on the cluster.
We are sorry you had a less than ideal experience. There is continuous work in progress on all aspects of Nutanix product family. I hope you will try it again in the future with a far more satisfying outcome.
