The "webs.img" file is a LVM partition, which primarily resides in
/dev/mapper and then you decided to mount it ?

Asunto: [Xen-users] how to expand disk inside of domU?
i'm trying to find a way to expand a selected partition in my
DomU...
when in a console in the domU, here are the disks available:
[root@localhost ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
13G 3.5G 8.1G 30% /
/dev/xvda1 99M 21M 74M 22% /boot
tmpfs 257M 0 257M 0% /dev/shm
I'd like to expand the /dev/mapper/VolGroup00-LogVol00 disk to 25G
The domU is based on an image file, 'webs.img' that resides on a disk
in the Dom0.
In the dom0, I add space to the webs.img file with the following
command:
dd if=/dev/zero bs=1024k count=12288 >> webs.img
then, when i create the webs domu, i.e. xm create webs;
it starts, and the new space shows up as "unintialized' space
in the domu. (I see this using vnc to reach the desktop, and
open the LVM tool to see the new space).
The problem that I'm having is to 'attach' the unintialized space in the
domU to the /dev/mapper/VolGroup00-LogVol00 disk, and then to expand the
LogVol00 disk to take advantage of the space.
I'm running Centos5 on the dom0, and in the domU. Xen is version 3.
Any suggestions? if so, can you please be explicit as to _where_ to run the various
commands, in the Dom0 or DomU? At this point, I'm pretty confused about
what to do where....
Thanks!
