An email asking more details has been received or clarification.
P485 is the draft for the answer.

Cheers,

Most of the relevant commits use the 192.168.128.0/24 address space.

That network is already being used for the communication between banco and its storage bay.
It would be wise to use a different IP prefix.

sesi asked for some more details about the hardware to propagate that vlan too.
I just replied, so hopefully, that should converge soon.

Also, ack @ftigeot for the address space clash. Thanks for the heads up.
That should change soon enough i think ;)

Cheers,

A priori, everything is done on sesi's side, as asked by @olasd, last ticket entries excerpt:

Bonjour
Les modifications sont faites, tiens moi informé si c'est bon de votre côté.
Bonne journée,
Hakim

Remains to check everything is fine and get back to them so we can close the ticket.

Cheers,

Is this now done? If that's the case this ticked should be closed.

The VLAN has been provisioned on our hypervisors, but not setup / in use yet.

I guess we'll do that when we go ahead and install the new hypervisor.

(the VLAN id for the staging vlan is 443).

I wanted to rename the bridges on the proxmox hosts to something clearer (like vmbr-staging) but it turns out that proxmox only supports bridges named /vmbr\d+/. Ugh.

So I guess the bridges will be named vmbr$<vlanid>, which means vmbr443 for staging.

I've added a bridge vmbr443 to all hypervisors.

I've checked that all hypervisors were able to ping one another over this bridge, using their ipv6 link local addresses.

sudo clush -w @hypervisors 'set -e; for addr in fe80::e872:32ff:feac:ef39%vmbr443 fe80::24a5:2aff:fee3:3552%vmbr443 fe80::c82e:c2ff:fe01:e77d%vmbr443 fe80::589c:d0ff:fe33:4daa%vmbr443; do ping -c3 $addr; done'

Now we just need to move the machines to this VLAN.
