[DRBD-user] drbdmanage v0.43 pre-release

[Dietmar Maurer]

I have still problems with live migration. 
First, it works now if if set:

# drbdmanage net-options --allow-two-primaries yes --common

But I thought it would be better to do it directly on the resource, so
I tried:

# drbdmanage net-options --allow-two-primaries yes --resource vm-100-disk-1

That also worked, so I tried to implement that inside the pve storage library.
I call set_drbdsetup_props() directly after auto_deploy:

------------
    my ($rc, $res) = $hdl->create_resource($name, {});
    check_drbd_rc($rc->[0]);

    ($rc, $res) = $hdl->create_volume($name, $size, {});
    check_drbd_rc($rc->[0]);

    my $redundancy = get_redundancy($scfg);;
    
    ($rc, $res) = $hdl->auto_deploy($name, $redundancy, 0, 0);
    check_drbd_rc($rc->[0]);

    ($rc, $res) = $hdl->set_drbdsetup_props(
	{ 
	    target => "resource",
	    resource => $name,
	    type => 'neto',
	    'allow-two-primaries' => 'yes',
	});
    check_drbd_rc($rc->[0]);
 -----------

That seems to work, but I end up with _standalone connections:

# drbdsetup show

resource vm-100-disk-2 {
    _this_host {
        node-id			1;
        volume 0 {
            device			minor 11;
            disk			"/dev/drbdpool/vm-100-disk-2_00";
            meta-disk			internal;
            disk {
                size            	2097152s; # bytes
            }
        }
    }
    connection {
        _peer_node_id 0;
        _this_host ipv4 192.168.3.202:7701;
        _remote_host ipv4 192.168.3.201:7701;
        _is_standalone;
        net {
            allow-two-primaries	yes;
            cram-hmac-alg   	"sha1";
            shared-secret   	"P28WJbG+4LnDRuMudukx";
            _name           	"hatest1";
        }
    }
    connection {
        _peer_node_id 2;
        _this_host ipv4 192.168.3.202:7701;
        _remote_host ipv4 192.168.3.203:7701;
        _is_standalone;
        net {
            allow-two-primaries	yes;
            cram-hmac-alg   	"sha1";
            shared-secret   	"P28WJbG+4LnDRuMudukx";
            _name           	"hatest3";
        }
    }
}

Why? How do I correctly set allow-two-primaries on resources?
