[yena]

Hello,
i have a raw image created by Acronis.
How can i Write it direct on LVM GROUP ?
( like the web-panel KVM creation on LVM Group ?)

I have tryed with
dd if=win2003.raw of=/dev/pve/vm-102-disk-1

but i have an error of no free space .. but in my VG i have a lot of free space ..
I Also see that dd create file but i think i nedd a block device:

hi

you are trying to dd to /dev/pve/vm-102-disk-1 (lv)

did you create that lv before?

try posting this command result
#lvdisplay /dev/pve/vm-102-disk-1


here
http://pve.proxmox.com/wiki/Migration_of_servers_to_Proxmox_VE
you could find some more info...

the lvs you see there with lvdisplay should be other vm's lvm disks.

think of the lv as your vm "physcal" disk. without that, you can't dd on it
