    Volume Space Used Larger Than Volume Size?

    Randy Stowell Newbie

      Here's the odd question of the day.

       

      I've got this one volume that is showing some weird stats where the used space is greater than the volume size.

      CS220 is running NOS 2.1.4.

      Nimble volume - 70 GB

      ESXi DataStore - 70 GB

      Windows volume size created on datastore - 60 GB

      The volume is simply a file store on an SFTP server so there's a lot of data churn going on over time.

       

      Volume Info:

      Performance policy: VMware ESX

      Block size (bytes): 4096

      Reserve: 0.00%

      Warn level: 90.00%

      Quota: 100.00%

      Snapshot reserve: 0.00%

      Snapshot warn level: N/A

      Snapshot quota: unlimited

      Snapshot count: 2

      Volume usage (MB): 109350

      Volume compression: 1.02X

      Volume space saved (MB): 2659

      Snapshot usage (MB): 12748

      Snapshot compression: 1.03X

      Snapshot space reduction: 14.45X

      Snapshot space saved (MB): 171507

       

      How can a volume sized ~ 70 GB and showing a usage size of ~106 GB be saving 2.6 GB of space?  Is there any way to 'fix' this oddity other than create another volume and just move the data?
