The LUN and volume are thin provisioned with space savings being pushed back into the aggr. I sent my ESX admin a DF on his volume because he said he is running low on space. Why is ESX reporting that he only has a 200 GB in the datastore to create additional VMDK but the array is reporting 1831 GB? ESX server is 4.0 and they use thick VMDKs?</P><P></P><P></P><P><SPAN style="text-decoration: underline; font-family: Calibri; ">Filesystem&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; total&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; used&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; avail&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; capacity&nbsp; Mounted on</SPAN> <BR /><SPAN style="font-family: Calibri;">/vol/esxvol1/&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 3072GB&nbsp;&nbsp;&nbsp;&nbsp; 1240GB&nbsp;&nbsp;&nbsp;&nbsp; 1831GB&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 40%&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; /vol/esxvol1/</SPAN></P></BODY></HTML> Thu, 05 Jun 2025 07:11:13 GMT mjgalloway 2025-06-05T07:11:13Z VMware + Dedup question https://community.netapp.com/t5/VMware-Solutions-Discussions/VMware-Dedup-question/m-p/61028#M5764 <HTML><HEAD></HEAD><BODY><P>We have a FAS3140 with a 3 TB volume with 3 1TB LUN's in the volume.
