Hi,

(353GB) is a total Snapshot used size on Source Volume.

If you list the snapshot list via (snap list vol_test) it will tell which snapshot is utilizing more and which one is connected to snapvault relationship.

Do you want to remove the heavy snapshot to reclaim the space?

Send the snapshot list and we can suggest further.

thanks for you reply here is the result of snap list:

> snap list vol_test
Volume vol_test
working...

  %/used       %/total  date          name
----------  ----------  ------------  --------
 34% (34%)   32% (32%)  Feb 09 10:23  dest_filer(XXXXXXXX)_source_filer_vol_test_qt1-src.0 (snapvault)

if i want to freeing space on this volume

i have to delete the relation snapvault and recreate it ?

regards

[raj_shrivastava11]

Hi,

I am afraid Yes. What R u running out of space on Netapp?

Any data deletion happened which filled up this base snapshot?

Do u run snapvault update on daily or hourly basis? 1 thing u can try is running a snapvault update, this will force a creation of new base snapshot and i guess after that u can clean this heavy snapshot without destroying the snapvault relation.

Yes, snapvault update will create a new snapshot on source. Then you can delete that 353GB old snapshot as the new snapshot will be the base.

You must wait for completion of the snapvault update.

Make sure that snapshot retention is more on destination.

Note: You must always calculate the rate of change of data at volume level before configuring snapvault.
