Does it work also with rbd,sheepdog,lvm ? (maybe this is the same formats that qemu-img ? )

drives name under proxmox are:

drive-virtioX
drive-ideX
drive-scsiX
drive-sataX

Hi all, 

Doing online storage migration will involve the following phases: 
Phase 1) Create remote block device 
Phase 2) Connect this block device to NBD (nbd_server_add [-w] device) 
Phase 3) Start nbd_server (nbd_server_start [-a] [-w] host:port) 
Phase 4) "drive-mirror", "arguments": {"device": "ide-hd0", 
"target": "nbd:host:port", 
"sync": "full", 
"format": "(qcow2|raw)" } 
Phase 5) "drive-reopen", "data": {"device": "ide-hd0", 
"new-image-file": "new block device", 
"format": "(qcow2|raw)"} 
Phase 6) Stop nbd_server (nbd_server_stop) 
Phase 7) Remove old block device 

Have I missed something? 

PS. I am struggling with this '"device": "ide-hd0"'. What is the 
correct way of specifying a block device in proxmox given the following 
configuration: virtio2: pve-storage1_lvm:vm-102-disk-1,size=2G
