Create Flexclone and spit to create clone of your Volume

NetApp® FlexClone® technology instantly replicates data volumes and datasets as transparent, virtual copies—true clones—without compromising performance or demanding additional storage space.

using recent snapshot we can create a Flexclone and splitting the volume will create actual volume clone. 


  If you need a temporary copy of your data that can be made quickly and without using a lot of disk space, you can create a FlexClone volume. FlexClone volumes save data space because all unchanged data blocks are shared between the FlexClone volume and its parent.

 Check wheather you have latest snapshot exists in your volume Or not using below command.

NetappFiler> snap list Volume1
 Volume Volume1
working...

  %/used       %/total  date          name
----------  ----------  ------------  --------
  0% ( 0%)    0% ( 0%)  Aug 25 13:52  NetappFiler(2016531614)_Volume1.79

  1% ( 0%)    1% ( 0%)  Aug 25 00:00  SqlSnap_08-25-2015_00.00.09
  2% ( 0%)    1% ( 0%)  Aug 24 18:00  SqlSnap_08-24-2015_18.00.10
  2% ( 1%)    2% ( 0%)  Aug 24 12:00  SqlSnap_08-24-2015_12.00.09
  3% ( 0%)    2% ( 0%)  Aug 24 06:00  SqlSnap_08-24-2015_06.00.09
  3% ( 0%)    2% ( 0%)  Aug 24 00:00  SqlSnap_08-24-2015_00.00.10

 in this case i am using snapshot 'SqlSnap_recent'.

Estimate the Aggregate space is enough to split your volume Or Not below command
NetappFiler> vol clone split estimate CLONE

Check Aggregate space availability using below command
NetappFiler>df -Ah
NetappFiler> vol clone split start CLONE
Clone volume 'CLONE' will be split from its parent.
Monitor system log or use 'vol clone split status' for progress.
