Answer

  • Before calculating the volume space consumed in the aggregate, check the volume option as below:
Data ONTAP 7-Modefs_size_fixed
 
Example:
NodeName> vol status -v voldp
         Volume State           Status                Options
         voldp online           raid_dp, flex         nosnap=off, nosnapdir=off, minra=off,
                                snapmirrored          no_atime_update=off, nvfail=off,
                                read-only             ignore_inconsistent=off, snapmirrored=on,
                                64-bit                create_ucode=off, convert_ucode=off,
                                                      maxdirsize=73400, schedsnapname=ordinal,
                                                      fs_size_fixed=on, guarantee=volume,

 
 
ONTAP 9: filesys-size-fixed
 
Example:
ClusterName::> volume show -volume voldp -fields filesys-size-fixed
vserver volume  filesys-size-fixed
------- ------- ------------------
svm1    voldp   True

 
  • If the status is 'On/True,' the volume file system is fixed. It does not reflect the real size occupied by the aggregate.
  • If the volume is read/write, turn it to 'Off/False' to check the volume space consumption by the aggregate.
