Resize LVM after cloning disk

Question

I have cloned a 160Gb disk onto a 1TB disk.

See here for the exact details. Clone ubuntu linux hard disk

I want the use the entire disk.

How do i get the volume to use the whole disk.

There where some suggestions in the previous post and i have googled around, But i'm not confident what is the best way forward.

Thanks

Answer 1

You grow LVM by either:

• Resizing the underlying block device and running pvresize, or
• Adding additional PVs to your volume group.

Your disk information above is a little unclear, so I'm going to ignore it and give you a general description of the procedure. If your 1TB disk is otherwise empty, except for the LVM partition, then you can simply:

• Use fdisk to increase the size of the partition
• Use pvresize to grow the LVM PV to match the size of the partition.

If you're mixing LVM PVs on your disk with other partitions...don't do that. But if you insist, you can create an additional partition covering the extra space, and then add it to your volume group:

• pvcreate /dev/sd??
• vgextend vg0 /dev/sd??
