[SOLVED] Unicast two nodes cluster to multicast.

[nakasix]

Hello,

I'm coming to ask you for help, because I have a problem with a cluster of two nodes. Indeed, my cluster operates in unicast mode, but I want to enable multicast.

I saw the document at : https://pve.proxmox.com/wiki/Multicast_notes

On the main node, the omping command gives:

omping -m XXX.XXX.XXX.XXX 100.65.1.1 100.65.1.2
100.65.1.2 : unicast, seq=1, size=69 bytes, dist=0, time=0.080ms
100.65.1.2 : multicast, seq=1, size=69 bytes, dist=0, time=0.329ms
100.65.1.2 : unicast, seq=2, size=69 bytes, dist=0, time=0.064ms
100.65.1.2 : multicast, seq=2, size=69 bytes, dist=0, time=0.073ms
100.65.1.2 : unicast, seq=3, size=69 bytes, dist=0, time=0.061ms
100.65.1.2 : multicast, seq=3, size=69 bytes, dist=0, time=0.092ms
100.65.1.2 : unicast, seq=4, size=69 bytes, dist=0, time=0.063ms
100.65.1.2 : multicast, seq=4, size=69 bytes, dist=0, time=0.080ms
100.65.1.2 : unicast, xmt/rcv/%loss = 4/4/0%, min/avg/max/std-dev = 0.061/0.067/0.080/0.009
100.65.1.2 : multicast, xmt/rcv/%loss = 4/4/0%, min/avg/max/std-dev = 0.073/0.143/0.329/0.124​

On the second node, the omping command gives:

omping -m XXX.XXX.XXX.XXX 100.65.1.1 100.65.1.2
100.65.1.1 : unicast, seq=1, size=69 bytes, dist=0, time=0.068ms
100.65.1.1 : unicast, seq=2, size=69 bytes, dist=0, time=0.059ms
100.65.1.1 : unicast, seq=3, size=69 bytes, dist=0, time=0.067ms
100.65.1.1 : unicast, seq=4, size=69 bytes, dist=0, time=0.068ms
100.65.1.1 : unicast, xmt/rcv/%loss = 5/5/0%, min/avg/max/std-dev = 0.059/0.065/0.068/0.004
100.65.1.1 : multicast, xmt/rcv/%loss = 5/0/100%, min/avg/max/std-dev = 0.000/0.000/0.000/0.000​

Interface configuration of main node is :

allow-vmbr1 bond1
iface bond1 inet manual
ovs_bonds enp131s0f1 enp1s0f1
ovs_type OVSBond
ovs_bridge vmbr1
ovs_options lacp=active bond_mode=balance-slb

auto vmbr1
iface vmbr1 inet manual
ovs_type OVSBridge
ovs_ports bond1 vlan0001

allow-vmbr1 vlan0001
iface vlan0001 inet static
address 100.65.1.1
netmask 255.255.255.0
ovs_type OVSIntPort
ovs_bridge vmbr1
ovs_options tag=91​

Interface configuration of second node is :

allow-vmbr1 bond1
iface bond1 inet manual
ovs_bonds enp131s0f1 enp1s0f1
ovs_type OVSBond
ovs_bridge vmbr1
ovs_options lacp=active bond_mode=balance-slb

auto vmbr1
iface vmbr1 inet manual
ovs_type OVSBridge
ovs_ports bond1 vlan0001

allow-vmbr1 vlan0001
iface vlan0001 inet static
address 100.65.1.2
netmask 255.255.255.0
ovs_type OVSIntPort
ovs_bridge vmbr1
ovs_options tag=91​

Thank you,

Hello,

Now, it works ! I change my bond from "ovs_options lacp=active bond_mode=balance-slb" to "ovs_options bond_mode=active-backup".
Maybe a problem with LACP.
