[pve-devel] Storage migration: online design solution

[Alexandre DERUMIER]

this works with nbd for me, if both storages are available from same host

sample using monitor command:


vm is use rbd storage, virtio0
destination drive is a sheepdog volume (that I have create before)


#drive_mirror -n -f drive-virtio0 sheepdog:127.0.0.1:7000:vm-144-disk-1

# info block-jobs
Type mirror, device drive-virtio0: Completed 1073741824 of 1073741824 bytes, speed limit 0 bytes/s

mmm,this is the right name. 
you can use "info block" monitor command to see name 


# info block 
drive-virtio1: removable=0 io-status=ok file=/mnt/pve/netapp-Vserver-pnfs/images/vm200/vm-200-disk-1.raw ro=0 drv=raw encrypted=0 bps=0 bps_rd=0 bps_wr=0 iops=0 iops_rd=0 iops_wr=0 
drive-virtio0: removable=0 io-status=ok file=/mnt/pve/netapp-Vserver-pnfs/images/vm200/vm-200-disk-2.raw ro=0 drv=raw encrypted=0 bps=0 bps_rd=0 bps_wr=0 iops=0 iops_rd=0 iops_wr=0 

you can have a look at qmp resize command in proxmox code (QemuServer.pm), it's using drive device as argument.
