LVM trouble adding new drive

[Denis Witt]

Hi,

i'm running Edgy on an VIA embedded PC with a 250GB HDD in a LVM-Group 
named "Ubuntu". This was the only drive in this device and of course i'm 
booting from this drive.

Now i want to add a second drive, it's excatly the same model as the 
already installed one.

So i put the drive into the PC and started Edgy, everything fine:

cfdisk /dev/hdc
   => hdc1 => 0x8e
     => Everything fine


pvcreate /dev/hdc1
   => Got error message:

root at fenchurch:~# pvcreate -v /dev/hdc
     Wiping cache of LVM-capable devices
     Wiping internal VG cache
   Device /dev/hdc not found (or ignored by filtering).

pvcreate /dev/hdc1 -v --force
   => Seems fine:

root at fenchurch:~# pvcreate -v /dev/hdc1 --force
     Set up physical volume for "/dev/hdc1" with 488391618 available sectors
     Zeroing start of device /dev/hdc1
   Physical volume "/dev/hdc1" successfully created

vgextend Ubuntu /dev/hdc1
   => this damn thing won't work:

root at fenchurch:~# vgextend Ubuntu /dev/hdc1 -v
     Checking for volume group "Ubuntu"
     Archiving volume group "Ubuntu" metadata (seqno 3).
     Adding physical volume '/dev/hdc1' to volume group 'Ubuntu'
   No physical volume label read from /dev/hdc1
   /dev/hdc1 not identified as an existing physical volume
   Unable to add physical volume '/dev/hdc1' to volume group 'Ubuntu'.

Don't have a clue. Any hints?

Thanks!
