Hi I'm pretty sure there is nothing wrong with the LVM partitioning - I am using the same partitioning/methods on a older (ubuntu 10.04) server. Just a note it is a Ubuntu 12.04 server that has the issue... ------------------------------- vgdisplay vgpool --- Volume group --- VG Name vgpool System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 55 VG Access read/write VG Status resizable MAX LV 0 Cur LV 6 Open LV 3 Max PV 0 Cur PV 1 Act PV 1 VG Size 874.77 GiB PE Size 4.00 MiB Total PE 223941 Alloc PE / Size 35789 / 139.80 GiB Free PE / Size 188152 / 734.97 GiB VG UUID uPK29Y-cygJ-irzN-4rX1-9MLk-WDQ5-3UWlRo ------------------------------ lvcreate -L 4000M -n lvol0 vgpool Logical volume "lvol0" created mkfs -t ext4 -m 1 -v /dev/vgpool/lvol0 virt-clone -o centos6template-DONTSTART -n centos6.new -f /dev/vgpool/lvol0 ERROR Clone onto existing storage volume is not supported: '/dev/vgpool/lvol0' Still getting the same thing Any ideas how to troubleshoot this further ?
