Dear All
I can not understand the following event:
I have an NFS Data Store which I have cleaned up, I have moved all VMDK Files and have deleted some orpahn VMDK's, because I have space problem on this data Stor,
therefore I have now only just some VSC snapshot backups on this NFS Data Store and nothing else, but when I look at the snapshot size of this volume I can see the following picture:
  
(NetApp Release 8.1 7-Mode: Thu Mar 29 13:56:17 PDT 2012)
SANAASAN02*> snap list ESX_OS
Volume ESX_OS
working...
  
  %/used       %/total  date          name

SANAASAN02*> df -h ESX_OS
Filesystem               total       used      avail capacity  Mounted on
/vol/ESX_OS/            1152GB     1039GB      112GB      90%  /vol/ESX_OS/
/vol/ESX_OS/.snapshot      128GB      486GB        0GB     380%  /vol/ESX_OS/.snapshot
I can see that 486GB are used for the snapshot's on this Data Store, but when I look this Data Store in my vCenter console, then I see that the same Data Store are displayed as Space Utilized as other with the size of 967.36GB, 
As I had already explained I have moved or deleted all VMDK Files from this Data Store, actually I have only the VSC Snapshot Backup on this Data store, and normaly nothing else therefore I can not understand exactly what occupies this space, Its very strange for me.
