[Solved] Migrating TrueNAS - Trouble with Network

[rakor]

Hi there,

I want to migrate my TrueNAS Core, which is running on a HP Microserver to a Provmox VM. I was not sure if the thread sould pe posted to Virtualisation or here, but as I think it is not a vm-specific issue I put it in here. Please move it if I was wrong.

I installed TrueNAS inside the VM, saved the config on the hardware-based-installtion and uploaded the config in the vm. This went all fine.
My problem is that I can not adjust the network settings.

On my hardware-box I had:
NICs: igb0-igb3
LAGG: lagg0 (using igb2 & igb3)
VLANs: vlan10 (using lagg0); vlan90 (using lagg0)
bridges: bridge10 (using vlan10 and having an IP), bridge90 (using vlan90 without IP).

vlan90 ist currently not in use.

The vm has 2 NICs (vtnet0 and vtnet1).

But I can not change the network-setting on the console as everytime I try it the restart of the networking and routing fails.

I can open a shell and activate a interface using:

# sysrc ifconfig_vtnet0="DHCP"
# dhclient vtnet0

And then I can access the GUI using the provided IP.

But in the GUI I can't change the network-settings too. I can change all the stuff I want (remove devices, set settings, etc.), then click the test-button, but there is only the spinning circle telling me to wait. If I refresh the website all settings are set back. I want to adjust all the settings to my wish.

Do you have any hint for me where to look at?
Thanks a lot

Perhaps start by sharing the ifconfig output from the VM, maybe there's something that will give a clue to it in that.

So, now I did a rollback. The system is now installed and the config is uploaded. The system did a reboot. I haven't tinkered at the settings right now to have a clean state.

ifconfig tells me this:

If I select the first Option in the TrueNAS CLI-menu I get:

When I got the GUI running using ifconfig (as explained in my first post), the gui showed even the igb0-igb3 interfaces.

the gui showed even the igb0-igb3 interfaces.

I still don't get what's happening physically there to make that a possibility... can you run through how you have told proxmox to connect the NICs to the TrueNAS VM?

And do they show up in lspci?

Hey there, now it is running... I did what I (thought) I did all the times before. If someone comes here later I'll show my way.

1. Create a VM im Proxmox and install TrueNAS (if vlans are necessary they can be set up in Proxmox, so we need no vlan-handling inside TrueNAS)
2. Export the setting in the old (hardware) TrueNAS-installation
3. Import the settings in the new (Proxmox) TrueNAS-installation (TrueNAS will reboot twice to aktivate the settings)
4. Open the CLI of new Installation
5. Open a shell and set networksettings for the vtnet0-device (for my infrastructure `ifconfig vtnet0 inet 10.10.10.10/24 up`) - Now the system was avaliable via gui.
6. Login via GUI and open the Network -> Interfaces.
7. Delete all vlans, obsolete interfaces, lagg-devices
8. If we need a bridge (I do as I have some jails running) set the corresponding interfaces (vtnet) to the bridge. For me vtnet0 (for vlan10) is a member of bridge10.
9. set an IP-adress. for the bridge10.
10. remove all IP-adresses from the interfaces (vtnet).
11. test the network-settings (now it was working as expected).
12. confirm the network-settings.
13. Insert the drives (via PCI-Passthrough).
14. Be happy.


Thanks for your advice ans patience. I don't know why it was not working the first 4 times, but I am happy it is running now!
