import existing virtual disks, lvm

[lievenva]

Hi,

I have installed proxmox on a system where I used to run libvirt + kvm.

server1:/etc# pveversion -v
pve-manager: 1.5-1 (pve-manager/1.5/4561)
running kernel: 2.6.32-1-pve
proxmox-ve-2.6.32: 1.5-2
pve-kernel-2.6.32-1-pve: 2.6.32-2
pve-kernel-2.6.24-9-pve: 2.6.24-18
qemu-server: 1.1-10
pve-firmware: 1.0-3
libpve-storage-perl: 1.0-6
vncterm: 0.9-2
vzctl: 3.0.23-1pve3
vzdump: 1.2-5
vzprocps: 2.0.11-1dso2
vzquota: 3.0.11-1
pve-qemu-kvm: 0.11.1-1
ksm-control-daemon: 1.0-2

I want to import existing lvm-disks of my vm's into proxmox. I added this file to /etc/qemu-server/:

server1:/etc# cat qemu-server/102.conf
name: LTSP
bootdisk: virtio0
virtio0: SAS:ltspsys
virtio1: SAS:ltspswap
virtio2: SAS:ltspvar
virtio3: SATA1:ltspdata
ostype: l26
memory: 2048
onboot: 1
sockets: 1
cores: 1
boot: cd
freeze: 0
cpuunits: 1000
acpi: 1
kvm: 1
vlan0: e1000=52:54:00:F9:31:E6

Proxmox interface seems to recognise this machine, but the virtual disks are given with a size of 0GB.

When I try to start this vm, the task-log of the start-task gives:

unable to parse lvm volume name 'ltspdata'

Any way to make proxmox recognise the virtual disks? Maybe rename, but then I should know what's the naming scheme....

Thanks a lot,

Lieven

Hi,
that sounds like that you don't define the storage (SAS and SATA1).

What is the output of

vgdisplay
lvdisplay
cat /etc/pve/storage.cfg

You should see a logical volume named ltspsys and so on.

Hi Udo,

I did define the volume-groups:

server1:/etc/pve# cat storage.cfg
dir: local
        path /var/lib/vz
        content images,iso,vztmpl,rootdir

lvm: SAS
        vgname SAS
        content images

lvm: SATA1
        vgname SATA1
        content images

lvm: SATA2
        vgname SATA2
        content images

dir: PVEISOS
        path /var/lib/pveisos
        content iso

dir: PVEBACKUP
        path /var/lib/pvebackup
        content images

What I did was rename the volumes:

lvrename SAS ltspsys vm-102-disk-1
lvrename SAS ltspdata vm-102-disk-2
lvrename SAS ltspvar vm-102-disk-3
lvrename SATA1 ltspdata vm-102-disk-1

what did the trick.... (The machine now boots)

The size indication in the hardware device list is still 0GB. See attach....

check this

tags are needed and the lv needs to be named correctly
create a test lv and do the following

lvs -o lv_name,kv_tags,lv_size,vg_name

make your lv have the same naming convention and tagging convention (you can have multiple tags (I do, the proxmox tags are the first though)

Re: [solved] import existing virtual disks, lvm

Hi,

for the sake of completeness, this is what I did to solve the problem:

  512  lvchange --addtag pve-vm-102 /dev/SAS/vm-102-disk-1
  513  lvchange --addtag pve-vm-102 /dev/SAS/vm-102-disk-2
  514  lvchange --addtag pve-vm-102 /dev/SAS/vm-102-disk-3
  515  lvchange --addtag pve-vm-102 /dev/SATA1/vm-102-disk-1
  516  /etc/init.d/pvedaemon restart

Lieven
