<div>Ok guys...<br>
<br>
</div>
All those steps I already perform...<br>
</div>
I can shrink fs+partition+lvm inside the guest... Everything
is ok!<br>
</div>
But, when I perform this:<br>
<br>
</div>
<div>qemu-img resize vm.raw -3100G<br>
<br>
</div>
<div>the guest crash!<br>
<br>
</div>
<div>The raw image, on Proxmox fs has 3,9 TB...<br>
</div>
<div>Inside the guest, I have this:<br>
<br>
df -h<br>
Filesystem Size Used Avail Use% Mounted on<br>
/dev/mapper/vg_bancosiscobra-lv_root<br>
50G 4,7G 43G 11% /<br>
tmpfs 939M 0 939M 0% /dev/shm<br>
/dev/sda2 485M 67M 393M 15% /boot<br>
/dev/mapper/vg_bancosiscobra-lv_home<br>
640G 540G 68G 89% /home<br>
<br>
</div>
<div>With the qemu-img resize command showing above, I managed
to shrink raw image to 800GB, more than sufficient to boot the
machine...<br>
</div>
<div>But no way! I get error inside the guest...<br>
<br>
</div>
<div>My next shot will be this tutorial:<br>

But, when I try to use qemu-img resize,
perhaps I mistake something, because the crash
down in kernel panic, 'cause not found and
partitions, even the LVM!<br>

Are you sure that gparted live iso is safe???<br>

<div>Use the GPartEd Live ISO (<a href="http://gparted.org/download.php" target="_blank">http://gparted.org/download.php</a>)
to resize the LVM *and* the partiton, then
qemu-img to shrink it.<br>

<div>Hi guys<br>
<br>
</div>
I was able to reduce
LVM and root/home
partition inside a
certain VM, runnning
on Proxmox.<br>
</div>
The VM has raw image.<br>
</div>
<div>This image was 4 TB
of size..<br>
</div>
But, when I try using
command:<br>
<br>
qemu-img resize vm.raw
-XXXXG<br>
<br>
</div>
The VM get crash! No
partition remain....<br>
<br>
</div>
So I thought use virt-resize
to make this operation....<br>
</div>
I can use perhaps, other host,
with virt-manager and other
virt tools installed, shrink
the raw image with virt-resize
and get use the resulting
image to new VM on Proxmox...<br>
<br>
</div>
Or, maybe you guys, has another
solution...??<br>
<br>
</div>
