File system level trim is enabled for a storage device designed to perform “read return zero” after a trim or an unmap operation. Nimble also supports this, and space is actually freed up on the array when garbage collection takes place. </SPAN></SPAN></P><P><SPAN style="color: #454545; font-size: 14px; font-family: 'Segoe UI', 'Lucida Grande', Verdana, Arial, Helvetica, sans-serif;"><BR /></SPAN></P><P><SPAN style="color: #454545; font-size: 14px; font-family: 'Segoe UI', 'Lucida Grande', Verdana, Arial, Helvetica, sans-serif;">For additional info, here is a pretty good read: <A href="http://msdn.microsoft.com/en-us/library/windows/hardware/dn265487(v=vs.85).aspx" title="http://msdn.microsoft.com/en-us/library/windows/hardware/dn265487(v=vs.85).aspx">Thin Provisioning (Windows Drivers)</A><BR /></SPAN></P></BODY></HTML> Mon, 27 Oct 2014 22:14:12 GMT https://community.hpe.com/t5/array-setup-and-networking/how-to-get-array-space-back-after-deleting-data-at-os-level/m-p/6985189#M1618 bgrieve65 2014-10-27T22:14:12Z Re: How to Get Array Space Back after Deleting Data at OS level? https://community.hpe.com/t5/array-setup-and-networking/how-to-get-array-space-back-after-deleting-data-at-os-level/m-p/6985190#M1619 <HTML><HEAD></HEAD><BODY><DIV><P>Search the forum for 'reclaim space' for info and scripts you can run to return space to the array on win 2003/2008.
