Network & Services - Configuration

Hello all,

I have a proxmox cluster with :
- Physical host A
- Physical host B
- Virtual host C for HA

Between Physical hosts, I have a lvm drbd shared for the VM (Primary/Primary; Sync is OK).

For each physical host, have two NIC.
This NICs is in bond0 and the bond0(-rr) is associate to vmbr0 at 192.168.10.1/24. (And 192.168.10.2/24 for the second host).

Now for the VMs, we need severals networks.
Indeed, we have :
- 192.168.10.1/24 (X-10) for the network admin (IP to physicals hosts and VMs eth)
- 192.168.20.1/24 (Y-20) and 192.168.30.1 (Z-30) for the VMs.

Each network is in differents vlans(10-20-30).

VMs (one eth per network) communicate on all network between all physical hosts but the server have only 2 NIC.

For me, the physical host configuration is :

==========
HOST A
==========

==========
HOST B
==========

The configuration doesn't work.

For the drbd cluster, I have a desync. Impact is if we migrate a VM to the second host while the desync, the VM not boot and have : "/Booting from Hard Disk ; Boot failed: not a bootable disk".
So, I shall stop the VM for stop the use ressource, and restart drbd service on two physical hosts for recovery my drbd service = HA lost.

I need that the drbd is up automatically when this is down.
( Heartbeat ? Pacemaker ? What's actions ? )

In the second part, what is the best solution for my network configuration ? Dummy interfaces ?

thanks per advance !


Edit :

I think at this for the network configuration :

What do you think to this ?

Thanks
