Dell PowerStore NFS Copy Offload API

A feature for effective creation of a volume from snapshot/volume was added in PowerStore NFS Driver. The dellfcopy utility provides the ability to copy a file very quickly on a Dell SDNAS filesystem mounted by a client. To download it, contact your local Dell representative.

The dellfcopy tool is used in the following operations:

  • Create a volume from a snapshot.

  • Clone a volume.

To use PowerStore NFS driver with this feature, you must install the tool with the following command:

# sudo dpkg -i ./dellfcopy_1.3-1_amd64.deb
