LVM query

[adm-computers]

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

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?

[adm-computers]

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 fdisk -l

Hi Falko,

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

fdisk -l

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

[falko]

Is /dev/sdb the drive that you added?
