If you want to go for exact caliculation, go for mb or kb level. Then only you will get exact caliculation. NetApp will prefer round figures. If you have a 1GB volume and that is used 900MB but if you check t with df -g it will show u as 0 only.
Hi, thanks for the replies. Here is the output. It looks like aggr show_space shows the actual used space of the volume vol_vmware_nfs. Can you help me understand why there is such a difference between the two outputs (9.2TB with df-m and approx 6.6TB with aggr_show_space?)
