fdisk -l

Disk /dev/xvda: 42.9 GB, 42949672960 bytes
255 heads, 63 sectors/track, 5221 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000

Disk /dev/xvda doesn't contain a valid partition table

Here are the exact commands I ran to create and partition the LV, based on
your previous suggestions:

lvcreate -C y -L 40G -n testvm VolGroupVM
echo \"1,,L,*\" | sfdisk /dev/VolGroupVM/testvm
mkfs.ext3 /dev/mapper/VolGroupVM-testvm

Have I missed something?


Thanks again,

Matt.
