For server storage, it would be nice to see the potentially allocated volumes (thin provisioned) that exists for container volumes which reside on that server. If we have an instance A that has thin-provisioned a 30GB disk, and another instance B with 100GB of thin-provisioned space, then we could potentially have overprovisiond according to what physically exists on disk. This is especially crucial if for some reason the workload is placed on a server with other running volumes that we are unaware are taking up chunks of the disk that are unussed.

While thin-provisioning is the way to go, it presents problems if not visible when the disk begins to quickly be consumed. This can cause other resources to starve or the entire machine to go unresponsive.
