As I see, this part of code:

sub parse_volume_id {
    my ($volid, $noerr) = @_;

    if ($volid =~ m/^([^:]+):(.+)$/) {
	return wantarray ? ($1, $2) : $1;
    }
    return undef if $noerr;
    die "unable to parse volume ID '$volid'\n";
}


Would expect something like this:

scsi0: san3.vw-web04:0.0.1.scsi-1IET_00140001

But it will break on such paths:

virtio0: /dev/disk/by-path/ip-192.168.112.68:3260-iscsi-iqn.2009-04.net.syneticon:san3.contact-pdc-lun-1
