NFS Data Storage on ESXi 4.1 with VSC4.1 Plugin

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

---------- ---------- ------------ --------

34% (34%) 27% (27%) Feb 08 04:00 SANDDSAN01(1573969455)_ESX_OS.924 (snapmirror)

42% ( 3%) 38% ( 2%) Feb 04 01:27 smvi__Consistent_20130204010006

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.

If you deleted VMDK files from the NFS share, then they will get locked into snapshot. That's why your snapshot space is so out of whack.

To fix this, delete your snapshots and then create a new backup to ensure you have a fresh copy of your desired VMDKs.

Since this issue was in early Feb, I assume the problem started to resolve itself once backups rolled off.
