[linux-lvm] pvcreate on a loopback device - error: (newbie)



Hello,

I had tried to do some test with LVM on a loopback device
follwing some tutorials on the web.

I get errors.
what I do is this:

dd if=/dev/zero of=/work/tmp/disk-image count=10240
mke2fs /work/tmp/disk-image
mount -o loop /work/tmp/disk-image /work/loop/    78  14:23

pvcreate /dev/loop1

error:
Failed to wipe new metadata area
 /dev/loop1: Format-specific setup of physical volume failed. Failed
to setup physical volume "/dev/loop1"


what did I do wrong ?

Regards,
John
