[linux-lvm] LVM configuration question....

Hi,
I just installed SuSE 7.2, I have the LVM configured, all storage is on
LVM except for '/'. It's working great. All storage is SCSI. I have one
9GB drive that I did not configure, that I left data I wanted to save.
So, I've copied everything I want from there back on to the new running
system. Now I want to add this disk to the Volume Group. So, I deleted
the partitions on it w/ fdisk. As I could read in the LVM whitepaper,
that's not good enough. So, I did:
dd if=/dev/zero of=/dev/sdc bs=1k count=1
And that didn't work. I noticed an (apparent) typo in the the whitepaper,
in that the comment made after the above command is "This command
overwrites the first 10k Bytes of a disk with zeros, deleting any
partition table." Well, since the command specifies bs=1k and count=1, I
suspect it only overwrites 1k. So, I tried w/ 'bs=10k count=1', 'bs=1k
count=10', and even 'bs=100k count=1'. All with the same results. When I
try to run 'pvcreate', I get:
# pvcreate /dev/sdc
pvcreate -- device "/dev/sdc" has a partition table
pvcreate [-d|--debug] [-f[f]|--force [--force]] [-h|--help] [-y|--yes]
[-v|--verbose] [-V|--version] PhysicalVolume [PhysicalVolume...]
So, can anyone offer me a clue as to the problem?
Thanks,
-Mark
