Hello,
I'm new using proxmox. I've been reading a lot of posts in this forum about this. But I can't still resolve my problem.

I have installed last version, proxmox 4.4 with the default configuration. I created a VM with a win 2012 R2 in local-lvm. This VM has a 1TB virtio disk. And I want to resize it to 30GB. I'm just testing things to learn how to do basic things in proxmox before I start creating VM in production.

As I have read:
- I hav shrink the volume in the windows guest. Now is 30GB and 969GB Unallocated.
- The VM has to be stopped. It is.
- The VM config is this:
Code:
root@TEST:/etc/pve/nodes/TEST# qm config 100
balloon: 8192
bootdisk: virtio1
cores: 4
ide0: local:iso/systemrescuecd-x86-4.9.1.iso,media=cdrom,size=500986K
ide2: none,media=cdrom
memory: 16384
name: TEST-2012R2
net0: virtio=3E:C7:16:D6:10:3B,bridge=vmbr0
numa: 0
ostype: win8
scsihw: virtio-scsi-pci
smbios1: uuid=f57dfa9f-a379-4e72-ba85-ebae7f6f1ef5
sockets: 2
virtio1: local-lvm:vm-100-disk-1,size=1000G
- The disk config:
Code:
root@TEST:/etc/pve/nodes/TEST# qemu-img info /dev/pve/vm-100-disk-1
image: /dev/pve/vm-100-disk-1
file format: raw
virtual size: 1.0T (1073741824000 bytes)
disk size: 0
- Then I run:
Code:
root@TEST:/etc/pve/nodes/TEST# qemu-img resize -f raw /dev/pve/vm-100-disk-1 -- -969G
Image resized.
- After that, the disk config is still the same:
Code:
root@TEST:/etc/pve/nodes/TEST# qemu-img info /dev/pve/vm-100-disk-1
image: /dev/pve/vm-100-disk-1
file format: raw
virtual size: 1.0T (1073741824000 bytes)
disk size: 0
- I change the disk size in /etc/pve/qemu-server/100.conf
Code:
balloon: 8192
bootdisk: virtio1
cores: 4
ide0: local:iso/systemrescuecd-x86-4.9.1.iso,media=cdrom,size=500986K
ide2: none,media=cdrom
memory: 16384
name: TEST-2012R2
net0: virtio=3E:C7:16:D6:10:3B,bridge=vmbr0
numa: 0
ostype: win8
scsihw: virtio-scsi-pci
smbios1: uuid=f57dfa9f-a379-4e72-ba85-ebae7f6f1ef5
sockets: 2
virtio1: local-lvm:vm-100-disk-1,size=30G

Nothing changes...

Anything wrong? I guess that I'm missing something (maybe some concept too) because of the new version. Why the disk file doesn't have the .raw extension? In /dev/pve/ are only links, where are stored the disks files in version 4.4, as I have read they are supposed to be in /var/lib/vz/images/ but this folder is empty.

Thanks in advanced!
