Hi,

 

I would like to know that what is difference between total used and total physical used as shown in below output

 

an0990-na-cl1::> volume show-space test_vol_iscsi

      Vserver : test_svm_iscsi
      Volume  : test_vol_iscsi

      Feature                                    Used      Used%
      --------------------------------     ----------     ------
      User Data                                5.02GB        50%
      Filesystem Metadata                       212KB         0%
      Inodes                                     16KB         0%

      Total Used                               5.02GB        50%

      Total Physical Used                       268KB         0%

 

For my every volume there is huge difference between the two, the above volume "test_vol_iscsi" has gurantee none.

 

an0990-na-cl1::> vol show-space testroskilde

      Vserver : an0990-na-cl1-fcp
      Volume  : testroskilde

      Feature                                    Used      Used%
      --------------------------------     ----------     ------
      User Data                               152.6GB        28%
      Filesystem Metadata                     64.85MB         0%
      Inodes                                     32KB         0%
      Snapshot Reserve                        27.50GB         5%

      Total Used                              180.2GB        33%

      Total Physical Used                     75.43GB        14%

 

The above volume testroskilde has space gurantee "volume"

 

 

Regards..

JP
