A Cinder volume corresponds to a file within the NFS share provided by a FlexVol.
The space is consumed when you write actual data in the Cinder volume.
ONTAP is not able to read the filesystem within the Cinder volume to tell if a block is in use or not, so removing a file inside the Cinder volume won't free space.
Only when you delete the Cinder volume, the corresponding file within the NFS share will be deleted, and the space will be reclaimed.
How do I enable trim(unmap / reclaim) when using the nfs cinder backend?

Info: Openstack release: Xena Netapp: FAS9000 Hypervisor: Cisco UCS SAN switch: Nexus 6000 Hello, I'm tryng to start new instance . The LUN is correctly created on the SVM but in block device mapping phase It returns this error: "Unable to update attachment.(Bad or unexpected response from the storage volume backend API: Driver initialize connection failed (error: NetApp API failed. Reason - 9023:LUN already mapped to this group))". I read this bug https://bugs.launchpad.net/cinder/+bug/1697490 but in my case the issue appears in the attaching phase. Any suggestion? Cristiano
