Failed to wipe start of new LV

[deeq]

I'm trying to create KVM guest with LVM storage. When adding new VM in web manager i get following error:

/dev/kvm/vm-102-disk-1: not found: device not cleared
TASK ERROR: create failed - lvcreate 'kvm/pve-vm-102' error: Aborting. Failed to wipe start of new LV.

I think it is same error when i'm trying to create logigal volume manually with ssh:
lvcreate -L 20G -n debian kvm

/dev/kvm/debian: not found: device not cleared
Aborting. Failed to wipe start of new LV.

If i add "-Z n" in "lvcreate -L 20G -n debian kvm" -command, everything is fine and i can create manually new logigal volume.

I'm runnig debian 6 with proxmox 2.0 rc1 (pve-manager/2.0/30bb4d33).

Here is vgdisplay:

Please can you rename your VG (the name 'kvm' is used otherwise).

kvm VG is not used otherwise. If i add "-Z n" to "lvcreate -L 20G -n debian kvm" command (lvcreate -Z n -L 20G -n debian kvm), everything is fine and i can create manually new logigal volume.

It is same error in proxmox web-gui if i dont use "-Z n" in lvcreate command.
