LVM query

I have added a new HDD to my LVM - I'm using webmin to display system details and It's only showing 22gb when it should be showing 32Gb.

The source I used to add the new volume can from this link

http://lucaschan.com/weblog/2007/06/29/adding-a-physical-disk-to-lvm-in-redhatcentos/

Have they missed something or does the LVM automatically increase the space when needed?

 

How did you partition the new drive? One big partition, or multiple smaller ones?

 

When I setup the server I used two hard drives and allowed it to auto configure the partitions so I'd imagaine it did 2 partitions - 1 large 1 small!!

I just want to try out LVM so it's on a VM so I can rebuild it if need be

I partition the new drive with one large partition

 

You can check that with

Code:

fdisk -l

 

Hi Falko,

Been a bit busy at the mo but here is the output of fdisk -l

Code:

fdisk -l

Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          13      104391   83  Linux
/dev/sda2              14       19457   156183930   8e  Linux LVM

Disk /dev/sdb: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1   *           1       19457   156288321   8e  Linux LVM

I've removed the third drive at the mo and am gonna add it again

 

Is /dev/sdb the drive that you added?
