They are not the same thing. The 11% is showing you “used / allocated” in your logical volume. Another words “15281032 / 151527604 = 11% “ however the free PE which is 160 MB, is the total unallocated space in the free bank of the volume group. You could use that to extend the existing one (151527604) or create a new one.<o:p></o:p> <o:p> </o:p> Hope that helped<o:p></o:p> <o:p> </o:p> <div> <div class=MsoNormal align=center style='text-align:center'> <hr size=2 width="100%" align=center tabindex=-1> </div> From: linux-lvm-bounces@redhat.com [mailto:linux-lvm-bounces@redhat.com] On Behalf Of Joann Deng Sent: Thursday, November 16, 2006 8:10 PM To: linux-lvm@redhat.com Subject: [linux-lvm] Rmove a faulty hard drive off LVM Group<o:p></o:p> </div> <o:p> </o:p> <o:p> </o:p> Hello,<o:p></o:p> <o:p> </o:p> My system is a Sun Fire X 2100 with RHEL 4.0.
