[pve-devel] Storage migration: online design solution

[Alexandre DERUMIER]

for the uri, you can do 

#info block

in monitor, this is the file=  part.

you can use proxmox sub path to generate it

my path = PVE::Storage::path($storecfg, $dst_volid);




migration part should be something like

$drive = "virtio0";
my $targetpath = PVE::Storage::path($storecfg, $dst_volid);
PVE::QemuServer::vm_mon_cmd($vmid, "drive-mirror", device => "drive-$drive", target => $targetpath);

while{
  PVE::QemuServer::vm_mon_cmd($vmid, "block-migrate-status");
}
      
PVE::QemuServer::vm_mon_cmd($vmid, "block-job-complete", device => "drive-$drive");

Found out that it has to be a URI: /dev/pve-storage2_vg/vm-102-disk-1 
works:-)
