Space allocation is an important NetApp driver specific feature. This needs to be set when the cinder volume is created. This is not related to thin/thick provisioning feature of cinder volumes.It is independent of that. It enables ONTAP to reclaim space automatically when host deletes data.This helps ONTAP and host to see the actual space correctly when the host deletes data. It also helps to keep a LUN (cinder volume) online when the LUN (cinder volume) in ontap runs out of space and containing volume (in ONTAP) cannot automatically grow more space. User can configure it by using volume type extra spec. By default Space allocation value is disabled for ONTAP LUN netapp:space_allocation: "<is> True" # to enable space allocation netapp:space_allocation: "<is> False" # to disable space allocation Blueprint: netapp-space-allocation-support Change-Id: Ib7072f3093067ecd8ad84e396aaecec8f15c49ba

NetApp iSCSI/FCP drivers: NetApp space allocation feature allows ONTAP
|
|
and host to see the actual space correctly when host deletes data.
|
|
It also notifies the host when the LUN cannot accept write data due
|
|
to lack of space on the volume, and makes the LUN read-only
|
|
(rather than going offline). This feature can be enabled or
|
|
disabled on cinder volumes by using volume type extra specs with
|
|
the ``netapp:space_allocation`` property. |
