[Xen-users] how do I increase a LVM based xen domU?

["Rudi Ahlers" <rudiahlers@xxxxxxxxx>]

Hi all

I know for many this is probably an easy answer, but I just can't figure it out. 

How do I increase the size of a xen domU that's installed on a LVM partition?

From what I can gather from Google searches, is that I need to use lvextend, but that doesn't seem enough. 

So, what do I need todo to extend a 5GB LVM to say 8GB?

I have the following setup:

[root@saturn plugins]# lvscan

  ACTIVE            '/dev/System/root' [10.00 GB] inherit

  ACTIVE            '/dev/System/swap' [4.00 GB] inherit

  ACTIVE            '/dev/System/pluto' [50.00 GB] inherit

  ACTIVE            '/dev/System/home' [10.00 GB] inherit

  ACTIVE            '/dev/System/data' [20.00 GB] inherit

  ACTIVE            '/dev/System/andrew_vmswap' [1.00 GB] inherit

  ACTIVE            '/dev/System/andrew_rootimg' [5.00 GB] inherit

  ACTIVE            '/dev/System/keith_vmswap' [1.00 GB] inherit

  ACTIVE            '/dev/System/keith_rootimg' [5.00 GB] inherit

  ACTIVE            '/dev/System/12_vmswap' [1.00 GB] inherit

  ACTIVE            '/dev/System/12_rootimg' [5.00 GB] inherit

  ACTIVE   Original '/dev/System/wiseguy_rootimg' [10.00 GB] inherit

  ACTIVE            '/dev/System/wiseguy' [5.00 GB] inherit

  ACTIVE   Snapshot '/dev/System/oldcpanel' [32.00 MB] inherit

And I would like to increase the size of /dev/System/wiseguy

Inside the domU, I get the following:

root@server [/scripts]# fdisk -l

Disk /dev/xvda: 5368 MB, 5368709120 bytes

255 heads, 63 sectors/track, 652 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

    Device Boot      Start         End      Blocks   Id  System

/dev/xvda1   *           1          13      104391   83  Linux

/dev/xvda2              14         652     5132767+  83  Linux

Can someone please tell me what commands I need to run to resize the LVM?
