UdoB reacted to Johannes S's post in the thread Wie geht man bei Verwendung von vGPU vor, um bestimmte Komponenten nicht zu aktualisieren? with
Like.
Am Besten gar nicht, weil jedes Update üblicherweise auch Securityfixes enthält. Laut der wikiseite arbeitet der nvidia-treiber mit dkms, dann sollte eigentlich bei einem Update auch das passende Modul neu gebaut werden. Falls es mal nötig sei... -
UdoB reacted to TErxleben's post in the thread Anleitung: Sicherung des PVE Hosts mit dem Proxmox Backup Server with Like.
Nein. Um komplette Images von Baremetalkisten zu ziehen sowieso nicht. Um Inhalte zu sichern gibt es z.B. BackupPC. Das kann man wunderbar virtualisieren und die entsprechende VM dann auf PBS sichern. P.S.: Ich sichere so z.B. per rsync auf...

UdoB reacted to Johannes S's post in the thread I want nothing more than encrypted push sync with Like.
If you care about security why would you want to use push-sync in the first place? With push-sync your local PBS can access and write to the remote PBS. A pull-sync on the remote PBS allows to close incoming network traffic on the remote PBS...

Or split it up in two clusters (one three-node/one two-node) and add a qdevice to the two-node cluster. This could even be a VM in the three-node cluster, since the fiber connection should ensure a fast-enough connection:

UdoB replied to the thread [SOLVED] NFS network configuration.There is no dedicated "master" as all nodes are equal. (When you look under "Datacenter --> HA Status" you can notice that the shown "master" node will vary, depending on the current availability.) Shared storage must be reachable/usable on each...
-
@r7Y2 Is it required for the remote nodes to be part of the same cluster? It might be an option to have a three-node main cluster and two stand-alone nodes in addition, depends on your setup and usecase of course.
-
We probably wrote our replies at the same time, hence you missed my explanation regarding that issue. But as I said in my second post, the remote site doesn't have an independent second physical link, hence no benefit in adding a second network...

Given I currently manually do an rsync to another drive, anything would be better than that. :D I don't really write a lot of data and photos/documents are manually backed up to Backblaze every so often. I don't think I have data that needs to be...

@brightrgb the docs are a little light on detail. We consolidated some info and provide a Python and Bash example in the hookscripts folder here: https://github.com/Weehooey/proxmox-lab-notes

Here is an example of a hookscipt that shuts down VM 100 (if it is running) before starting and starts VM 100 when it shuts down (and the host is not shutting down). #!/bin/bash if [ "$2" == 'pre-start' ] then if /usr/sbin/qm status "100" |...

Thanks guys for clarification. After having activating subscription and modifying the repo settings, I was able to install said package and thus run an arm64 guest. Thanks for your valuable support.

UdoB reacted to ca_masch's post in the thread Is there a way to backup the PVE Host to the Proxmox Backup Server (PBS)? with Like.
I faced the same question and built a little tool called TheReaniamtor for this purpose. It pulls the backups of the host configurations graphically via the API/SSH so that you don't have to do everything manually on the console. The Reanimator

UdoB replied to the thread Cluster with different number of links.Just use a simple USB-NIC for that second ring. This (personal view: USB-devices in general) is usually not recommended, but a second ring using sub-optimal devices is probably better than none. Of course both connections should (hopefully) be...

UdoB replied to the thread SSD wear with ZFS compared to BTRFS.I won't fight this. This discussion is interesting, though I did not verify their statements: https://github.com/kdave/btrfs-progs/issues/760

UdoB replied to the thread [SOLVED] PBS upgrade format is nice and clean.PBS 4 is on Trixie / Debian 13 PVE 8.4 is Bookworm / Debian 12 So... just upgrade and you get the new apt output "for free" ;-)
-
UdoB reacted to Impact's post in the thread [SOLVED] PBS upgrade format is nice and clean with Like.
Check apt -v for the version difference. You should not use apt upgrade, by the way: https://lists.proxmox.com/pipermail/pve-devel/2025-March/068874.html

Ergänzend zu IsThingOn: Der PBS setzt für seine ganze Magie keine speziellen Features des Dateisystems heraus, man kann darum so ziemlich jedes Dateisystem nehmen, was von Linux unterstützt wird und Posix-Semantiken unterstützt (also zfs, btrfs...

Du vermischt hier zwei verschiedene Themen. Das eine ist ZFS dedup. Die dedup Table kann heutzutage auf svdev (also SSD) ausgelagert werden und muss nicht mehr im RAM sein. Das andere ist dedup mit PBS. Das braucht so ziemlich gar nix an RAM...

UdoB replied to the thread [SOLVED] NFS network configuration.Of cause there are multiple ways to set this up and there are definitely more details than would fit into one post. One possible quick-n-dirty approach: take a new unused switch (or use VLANs) connect one NIC on each PVE node here connect the...

That's surely an option, I personally would prefer to use ZFS features (like the bitrot-protection and compression)...
