[SOLVED] Cluster IP change?

[mle]

Hey all

I've reconsidered my network addressing in the course of which I would have to change the cluster IPs so that they fit into the scheme again.

Edge information:
1x cluster master
2x cluster nodes
Cluster IP is in its own VLAN via a lacp (802.3ad) works without problems so far.

Example: (for illustration only)

Spoiler: interfaces

auto lo
iface lo inet loopback

auto enpxxs0f0
iface enpxxs0f0 inet manual
mtu 9216

auto enp67s0f1
iface enp67s0f1 inet manual
mtu 9216

auto bond0
iface bond0 inet manual
bond-slaves enpxxs0f0 enpxxs0f1
bond-miimon 100
bond-mode 802.3ad
bond-xmit-hash-policy layer3+4
mtu 9216

auto bond0.1
iface bond0.1 inet manual
mtu 9216
#MAIN

auto bond0.2
iface bond0.2 inet static
address xx.xx.xx.xx/xx
mtu 9216
#Cluster

auto vmbr1
iface vmbr1 inet static
address xx.xx.xx.xx/xx
gateway xx.xx.xx.xx
bridge-ports bond0.1
bridge-stp off
bridge-fd 0
mtu 9216
#MAIN

I also want to change the main Proxmox IP including the domain name.
So that nothing goes wrong, I thought I'd ask the forum which files all have to be adjusted.

Thank you for your answers!

hi,

take a look here [0] and here [1]. you can change the IP configuration in the /etc/network/interfaces file but make sure the cluster configuration is adapted for that as well (see links below)
