Hi! You can try this to copy your Cinder Volumes (if LVM based): * At your new Cinder Volume server (new cinder-volumes LVM), run: root at cinder-volumes-server-1~# *nc -l 7000 | dd of=/dev/mapper/cinder-volumes-volume_id bs=32768* * From old cinder volume host (where your cinder-volume LVM resides): root at cinder-volumes-old-server-1~# *dd if=/dev/mapper/cinder-volumes-volume_id bs=32768 | nc cinder-volumes-server-1 7000* Source: http://toast.djw.org.uk/tarpipe.html If they are located within the same subnet/mask (netcat traffic), this will run pretty fast!
