This will just reduce the VMDK’s usage on the VMFS datastore NOT resize the “provisioned size” of a thin disk. To shrink a VMDK we can use an ESX command line tool “vmkfstools”, but first you […]
I have had the need recently to expand a LUN on a Dell MD3000i SAN to above 2TB that is presented to VMWare ESX 5.1 hosts. There are a few caveats here: Why not follow @mylesagray on Twitter for more like this!
