Change IP on hypervisor

[hojan]

Hi,

I have read all threads here on how to change IP on a PVE server node. They all boil down to the same thing, the .members file should update itself
once the correct entry is added to /etc/hosts. I have tried this several times, but my first node always remain on the old wrong IP.
I have changed the subnet, the first node picked up it's correct IP but the other one refuses to update.
pvecm status reports the correct IP for each host. The clusterconf has the correct names. /etc/hosts and DNS has the correct entries, and resolv.conf checks hosts first.
drbd works, I can live migrate from the first node to the second, but not the other way since the IP is wrong...

Expected IPs are
beast 10.6.5.46
beauty 10.6.5.47

But beast always remain on the old IP 10.6.6.46.

What more can I check? Is there a step I have missed?

Have you tried to change:

root@beauty:/etc/pve# cat .members
{
"nodename": "beauty",
"version": 9,
"cluster": { "name": "sthlm-proxmox", "version": 8, "nodes": 2, "quorate": 1 },
"nodelist": {
  "beast": { "id": 1, "online": 1, "ip": "10.6.[COLOR=#ff0000]6[/COLOR].46"},
  "beauty": { "id": 2, "online": 1, "ip": "10.6.5.47"}
  }
}

to

root@beauty:/etc/pve# cat .members
{
"nodename": "beauty",
"version": 9,
"cluster": { "name": "sthlm-proxmox", "version": 8, "nodes": 2, "quorate": 1 },
"nodelist": {
  "beast": { "id": 1, "online": 1, "ip": "10.6.[COLOR=#ff0000]5[/COLOR].46"},
  "beauty": { "id": 2, "online": 1, "ip": "10.6.5.47"}
  }
}

.members is a read-only file that's compiled when creating a cluster configuration. At least that's my understanding. Otherwise this would have been easy. =)

maybe removing/adding again the node from cluster fixes the problem?

Yes if that's the only way. I was hoping for a more online way of doing it, without taking the VMs offline.

Could he use pvesh set nodes/localhost/network/eth0 -type eth -address IP -netmask xxx ?
