Okay. So despite everything, I have been successful in giving my main proxmox server more votes. That should make it okay to just have 2 nodes from what I've been told and have read in their forums.

I did read the documentation for un-clustering. I have a hot take for the #proxmox devs: it should be as easy to uncluster as it is to cluster.

Am gestrigen Regentag nahm ich meinen Mut zusammen wollte meinen #Heimserver von #Proxmox 6.4 auf 7.x updaten. Viel zu spät war ich dran, aber es lief seit Jahren alles so schön fehlerfrei. Leider fror das Upgrade bei 58 % ein. Ich konnte herausfinden, dass es etwas mit „memtest“ zu tun hat. Nachdem ich diesen Prozess abschoss, lief das Upgrade bis zum Ende durch jedoch nicht fehlerfrei: Ich kam nicht mehr ins Proxmox-Gui, da „pveproxy“ und „pveservice“ (oder so) nicht mehr starteten. 😞 1/3

Whew! #Proxmox host went belly up, took me seven hours to fix even with backups.

TWO SSDs failed this morning.

Manufacturing-Lab mit Proxmox und OctoPrint

Ich steuere meinen 3D-Drucker mithilfe von OctoPrint, welches als LXC auf Proxmox läuft. Proxmox hat dabei seinen eigenen Desktop, mit dem man auf den Webhost von OctoPrint zugreifen kann.

Just added #Ubuntu Server 24.04 - https://github.com/dustinrue/proxmox-packer. I need to update the page on my site with some details about how to configure cloud-init in Proxmox yet. But long story short, you must set the ip config to enable DHCP. RHEL variants don't need this.

Thoughts on Proxmox and Home Lab Use

This post is really a small collection of thoughts about Proxmox when used in a home lab situation and home labs in general. I was originally going to post this to Mastodon only but it didn't fit in a single post.

A lot of people (at least what I see on reddit) build Proxmox systems with shared file systems like ceph, even for home lab use.

DO NOT to .04 on if you use , the containers will NOT start. I believe this is something that needs to be fixed by the proxmox team as they seems to be checking for ubuntu version manually in a startup script

@alternativeto good for #proxmox #homelab people 😎

loongarch I have looked up:
its a risc type of instruction set for (specific?) risc cpu's

I totally understand men that obsess over their lawn. I do the exact same thing with my home network.

Today I pondered something: Proxmox and others boast native ZFS integration as one of their strengths. Many Proxmox features rely on ZFS's unique capabilities, and many setups are built around them. If Oracle were to send a cease and desist tomorrow, how would the situation unfold?

A question for the #network-guys here:

I've got the 192.168.1.x network with HA in there. Now, I've got an #OpenWrt router with the IP 192.168.1.190 creating 2 new networks: 192.168.100.x. I now want to get the HA into the 192.168.100.x network, but I can't connect it physically, as both the OpenWrt and HomeAssistant run in containers/VMs on #proxmox. I tried experimenting with IP routes, but no success. Does anyone have a clue for me?

Bon, je suis complètement à court d'idées, j'ai besoin d' #aide sur du #reseau sur ce serveur... Si vous avez une idée ou si vous pouvez partager, j'en peux plus là

Le serveur qui fait tourner cette instance est sur un #proxmox. Jusqu'ici, tout allait bien.
Hier, suite à un plantage, j'ai du reboot le serveur (VPS chez Ionos). Après redémarrage, impossible d'accéder à quoi que ce soit : Interface Proxmox, services dans les conteneurs, rien.

La configuration était la suivante :

Interface externe (ens6) et 2 bridges :

  • vmbr0, en bridge-port sur ens6 (avec donc son ip publique), utilisé pour l'administration
  • vmbr1, avec une ip dans un réseau en 192.168.2.0/24 qui sert les conteneurs (reverse proxy pour un et docker pour l'autre)

J'ai dans mon fichier d'interfaces pour vmbr1 ceci :

        post-up echo 1 > /proc/sys/net/ipv4/ip_forward
        post-up iptables -t nat -A POSTROUTING -s 192.168.2.0/24 -o vmbr0 -j MASQUERADE
        post-up /script/dnat.sh
        post-down iptables -t nat -D POSTROUTING -s 192.168.2.0/24 -o vmbr0 -j MASQUERADE

Pour les ouvertures de port, j'ai dans dnat.sh des entrées comme celle ci (exemple pour le port 443)

iptables -t nat -A PREROUTING -i vmbr0 -p tcp --dport 443 -j DNAT --to-destination 192.168.2.10:443

Après debug, j'ai vu que le trafic passait à nouveau lorsque je foutais en down VMBR0.

J'ai donc, dans l'urgence, changé mes règles pour retirer vmbr0 et le changer par ens6, qui est le nom d'interface "physique".

J'ai pu constater que tout était revenu : accès à l'interface de proxmox, accès aux conteneurs... tout sauf, un point important : impossible depuis le serveur d'utiliser sa propre ip publique.

Par exemple, impossible pour l'instance d'envoyer un mail (le conteneur de mailing est situé derrière la même ip), impossible même depuis le shell de proxmox... ou encore impossible de renouveler les certificats sur le conteneur qui fait reverse.
