Moving proxmox to another network

[gerdnl]

He all,
Im gona move my proxmox server to another location and i was wondering how to setup my /etc/network/interfaces
this current /etc/network/interfaces is setup by my old webhost.

The webhost where im going to provided me with 2 uplinks that go to my 1800-24g (default setup)
i have my 3 nodes connected to the switch

how do i setup my /etc/network/interfaces now
vmbr159 and vmbr168 are vlans provided my old host
that should become 1 bridge that allows all my incomming ipnumbers from the new provider

Wil removing vmbr168 and changing vmbr159 to vmbr0 work? i gues 0 or 1 is the default vlan in my switch


this is the old one
---------------------

auto lo
iface lo inet loopback


auto eth0.159
iface eth0.159 inet manual


auto eth0.168
iface eth0.168 inet manual


auto eth1
iface eth1 inet manual


auto vmbr159
iface vmbr159 inet manual
bridge_ports eth0.159
bridge_stp off
bridge_fd 0


auto vmbr168
iface vmbr168 inet manual
bridge_ports eth0.168
bridge_stp off
bridge_fd 0


auto vmbr907
iface vmbr907 inet static
address 10.90.7.10
netmask 255.255.255.0
gateway 10.90.7.1
bridge_ports eth1
bridge_stp off
bridge_fd 0

I've tried it once but it was no succes. Changing the external IPs of a cluster is, if I'm not mistaken, officially not possible.

Perhapse the best way is to dismantle the cluster at the old site, so remove all nodes from the cluster. And create a new cluster on the new location.

Never tried it, but might work.

 

[gerdnl]

its not setup as a cluster each machine for itself.

Then it's easy, just change the /etc/network/interfaces settings, the /etc/hosts and reboot the server.
