Support thin provisioning for NSS Volumes

Support thin provisioning for NSS Volumes

Customers want to save space on their SAN by thin provisioning volumes but if something like Salvage is enabled, the free space on the volume, and therefore all the space that was saved on the SAN by thin provisioning, will be filled with salvageable files.

I agree, there should be a option on NSS to release free blocks if we want it for thin provisioning, since NSS is needed for CIFS/AD and other services we can not use a different file system with those services.

It is really strange that NSS still lacks support for the Logical Block Provisioning feature as defined in the SCSI SBC-3 standard.

support for SCSI UNMAP is desirable so SAN is aware of what space is free and can appropriately re-tier or re-use if thin provisioning. I don't believe salvaged files are relevant here as they count as used blocks. sputils was added in OES2018 to purge files older than X days to reduce space used by salvaged files.

Yes it's basic function what file system should have!
