    You may read the release notes before executing an upgrade ;-) --> https://pve.proxmox.com/wiki/Upgrade_from_8_to_9#cgroup_V1_Removal

    Are you sure the answer of "ping" came from this server? Or does it come from the machine using that IP address in that moment? (Hint: you can not know that without examining the MAC address.) The first suspicion is an IP address conflict. I...

    Yes, if you loose 4 out of 8 nodes you have an issue. You need to have an odd number of nodes. If you have your cluster split in two rooms, you need the deciding vote (could be a q-device) located in a 3rd room/location. It should be equally...

    Solid advice - I'll look into this option as well, thanks. Yup, that scenario has not escaped my thought process - plan on doing the Q-Device for as long as I have an even number of nodes but might try and experiment with the "maintenance-mode"...

    @UdoB is correct for a one-time procedure. It may be a good time to think about what would happen in a non-orderly shutdown (loss of the room), and to implement good practices. Cheers Blockbridge : Ultra low latency all-NVME shared storage for...

    Integrating an independent Quorum Device is the correct solution for "normal use". You go for maintenance and I expect you to have an eye on the remaining cluster during that time. In this case you can circumvent the Quorum problem by telling...

    Darum ist PBS empfehlenswert, dessen Deduplizierung spart einiges an Speicherplatz, die Performance mit Netzwerkfreigaben macht aber nicht gerade Freude, mit lokalen SSDs ( oder notfalls HDD im mirror mit einen ssd mirror als special device) ist...

    UdoB reacted to Johannes S's post in the thread Kein Backup über PBS with Like Like.
    Der Punkt ist halt, dass es mit Netzwerkfreigaben generell langsamer und fehleranfälliger ist. Im NFS-Thread hat der User mit den Umzug auf eine VM direkt auf der NAS eine deutliche Beschleunigung für die regelmäßigen Wartungsjobs (garbage...

    Viel wichtiger finde ich bei solchen Setups noch das Backup. Aber auch für den ProxmoxBackupServer eignet sich günstige alte Hardware ganz gut ;) Und wenn man einen Mini-PC nimmt, hält sich der Stromverbrauch ja in Grenzen, grün hin oder her...

    UdoB replied to the thread Problems about PBS verify workers.
    Yeah, that's great! :-) Maybe. Maybe not. How much Ram does the system have? For ARC? When you started that command for the first time the very first thing it does is to create the testfile by writing to it. After doing so the whole content...

    Ernst gemeinte Frage (nicht böse gemeint!): Warum setzt man ein System in der Firma auf, was man nur mit KI eingerichtet bekommen hat? Schon zuhause wäre mir das zu heikel (kann man aber natürlich auch anders sehen, je nach dem wie wichtig einen...

    UdoB replied to the thread Problems about PBS verify workers.
    During backup (=writing new data) or verify = reading chunks? Assuming verify for now, so: You have three vdevs --> the IOPS of three spindles. You need to read a lot (approx. 12 million) of 4 MiB chunks, several will be smaller. 66 MB/s per...

    UdoB reacted to leesteken's post in the thread Proxmox Pihole Fehlermeldung with Like Like.
    Are you running your Pihole in a unprivileged container? Then this is normal, since containers share the Proxmox host kernel and don't have this permission. Change you Pihole to stop trying to sync the hardware clock with network time. EDIT: I...

    Yes, and I will link you to my desperate post on truenas forum https://forums.truenas.com/t/multiple-issues-half-recovered-now-but-have-question/50320 This is me, and this is the same issue, I just approached it from a different angle

    UdoB reacted to Johannes S's post in the thread newbie questions about replication with Like Like.
    Nope it's not. But: A cluster brings additional complexity and (thus) additional potential failures. For example: You should have at least three nodes like explained by Udo above. That can be mitigated with a qdevice (a raspberry would work or a...

    Mittlerweile nicht mehr: Dafür halte ich auch den Weg mit der Storage-Replication für den Schmerzfreiesten mit dem geringsten Ausfallrisiko. Ja, man hat da im worstcase einen Datenverlust von einer Sekunde und es mag Anwendungen geben, wo das...
  • UdoB
    This is correct, the user and their permissions apply to all nodes in the cluster. System-Wide refers to "Linux PAM" which is not PVE specific. Its a generic Linux concept. The "system" in this particular wording is the server/node. Each...

    UdoB reacted to Sviat's post in the thread PBS 4 on bookworm with Like Like.
    Hello, Running PBS 4 on Debian 12 Bookworm is not officially supported, and while it might be technically possible to force the installation, you’d be stepping into risky territory. It may encounter dependency conflicts, especially with newer...

    Yes, there is no need to use ZFS and ZFS really shines with multiple drives. But a) ZFS replication b) transparent compression c) technically cheap snapshots d) data integrity checks / bit-rot-detection(!) and some more features (e.g...

    Technisch ist das aber dennoch ein SPOF, oder nicht? Wir reden hier aber von einem Homelab. Und selbst wenn der NFS-Server auf der oben erwähnten Synology ultra-stabil wäre: das essentielle Netzwerk ist vermutlich ebenfalls nicht redundant und...
