RspecExtensions/storage/1: storage.rnc

# An extension for specifying storage resources to reserve or already reserved within an RSpec.
# Based on http://geni-orca.renci.org/owl/storage.owl
# Storage is just a different kind of node. It uses a 'storage' sliver_type.
# A storage node has a client_id, component_manager_id, sliver_id like a normal node.
# It gets a component_id like a normal node as well.
# A storage node has interfaces as well.
# If the node connects via a shared VLAN, then it has a single interface on that VLAN.
# If the node connects via a dedicated VLAN, then it may have multiple interfaces.
# Hosted here: http://www.geni.net/resources/rspec/ext/storage/1/storage.xsd

# This is meant to extend the sliver_type element when its value is "storage"
# This may be used in request or manifest RSpecs
StorageSpec = element storage {
  # resource_type should be 'LUN' (aka iSCSI). Maybe 'NFS' in future
  attribute resource_type { xsd:string } &
  # do_format is a boolean: should the VM format the storage
  attribute do_format { xsd:boolean } &
  # fs_param is a string of arguments to mkfs. EG for an ext filesystem you need "-F -b <block size"
  attribute fs_param { xsd:string } &
  # fs_type is a string of arguments to mkfs, as in mkfs -t XXXX
  attribute fs_type { xsd:string } &
  # mnt_point: Where to mount the storage in the VM

  # Capacity is in GB; Reservable in fixed quanta usually.
  attribute capacity { xsd:integer } &
  # Connection type - shared VLAN or dedicated or either
