Hey,Sorry for the late reply as I was not on my computer and wasn't able to check that.So I have checked this out an as this is a legacy system I'm using VMFS 5 on this volume.I've tried to switch the volume to thin provision but I'm getting an error that the in use space exceeds the warning limit.Am I still able to do this procedure in the way that DELL-Sam L suggested?     EDIT:After using your provided help + this guide I was able to unmap my volume.used the following:esxcli storage vmfs unmap -u      Many thanks guys!
Hey Guys,I have a Dell EqualLogic array of two PS6210 that I'm having an issue with on of the volumes.I have a 2TB volume being used by VMWare VCenter and I started getting an error saying that the volume's used space is more than 98%. Of course in VCenter the volume is not used to that extent and is mostly free. [IMAGE]   Now, is there a way for me to reclaim that space back? Do I have to do something in VCenter first?Thanks!
