UdoB replied to the thread Setting vCPU over physical maximum, should not be fatal to start, just start with physical core count and pop a warning !.Well, usually we are talking "clusters". And it is wishful thinking that all nodes are equal. In fact one advantage here is that the nodes may widely vary. That dialog would need to limit the number of assigned cores to those of the smallest... -
UdoB reacted to cwt's post in the thread High Switch CPU due to Jumbo Frames / Video Streaming - Migrating Physical pfSense/DGuard to Proxmox? with
Like.
I think you are mixing up several different things here. A switch does not perform TSO. TSO is a host/NIC offload mechanism where the OS can hand a large TCP buffer to the NIC and the NIC segments it into normal Ethernet frames before... -
UdoB reacted to proxuser77's post in the thread Proxmox VE 7 is vulnerable to some type of 0day/RCE non auth with Like.
Fascinating. It’s the year 2026, and people are still having seven-page-long discussions about something that could have been prevented by following two simple rules that everyone should know by now. 1. Keep the software up to date and don't use...

UdoB reacted to Johannes S's post in the thread Proxmox VE 7 is vulnerable to some type of 0day/RCE non auth with Like.
Does OVH really deploy PVE7 still in 2026? Or isn't it more that folks start with some version and then never update due to the non-dying "never change a running system"-bullshit? And since you mention wireguard: If that's available why don't...

UdoB replied to the thread PBS ZFS disk speed thoughts option.This! That may be a good choice for some situations - however I can't imagine it is a good idea to drop all ZFS goodies. ((You all know what I mean; for interested new-to-ZFS-users...

Yea, well I dont see ZFS worse than any other filesystem in stealing storage for itself. Today i got 6x5TB (30TB disk) that gives my in a RAIDZ2 19,41TB So thats just 600GB that is on the loose! ;-) So I guessed that a 3x5TB RAIDZ1 should give...

UdoB reacted to shodan's post in the thread A missing ISO file should not prevent a VM from starting, it should just be a warning with Like.
Ok thanks ! I gave my 2 cents to 4225

UdoB replied to the thread PBS ZFS disk speed thoughts option.Keep in mind that the usable space will be less as ZFS uses some space "for its own". Then there is the 80%-rule: for good performance a pool should not get filled up more than 80%. Above 90% IO-operation may get really slow. (( And reaching...

UdoB replied to the thread PBS ZFS disk speed thoughts option.Just nitpicking - to avoid establishing "wrong" terms: Each of those groups (of three) disks result in a vdev. Any (practical) number of vdevs may be put into one pool. All vdevs in one pool are striped.

UdoB reacted to BassT's post in the thread Unofficial updater script for Proxmox VE (HOST / LXC / VM ) with Like.
**Ultimate Updater v5.1.2 – Hotfix released** A small but important hotfix release for Ultimate Updater 5.1. ### What’s fixed * fixed the self-update path for existing v5.0 installations * corrected release archive handling during...

UdoB replied to the thread A missing ISO file should not prevent a VM from starting, it should just be a warning.Yeah, that's annoying. You may create a bug report over at https://bugzilla.proxmox.com/ if there is none yet; look at: https://bugzilla.proxmox.com/show_bug.cgi?id=3869 https://bugzilla.proxmox.com/show_bug.cgi?id=4225

UdoB reacted to leesteken's post in the thread New PVE 9 node shows "unknown"/offline in GUI from PVE 7/8 nodes, despite cluster status/quorum being OK with Like.
Proxmox claims to support the latest update of PVE X for (and only for) upgrading to PVE (X+1) but (live) migrations from upgraded nodes to non-upgraded nodes are not supported. The whole cluster should first update to the latest 8.4 (which is...

Übrigens mit den 2,4TB 10k HDDs würde ich kein raidZ fahren und wenn dann nur mit mindestens 2 SSDs als Special Device. Wenn du nur 5 Disks hast, gewinnst du mit RaidZ2 eh nicht so viel und dann lieber noch eine Disk reinstecken und Mirror...

UdoB reacted to Johannes S's post in the thread Best Practice for moving backups to a namespace while maintaining the existing backup job chains with Like.
The deduplication will continue to work in any case since it's cross-namespaces as long as you have them all on the same datastore. To get the backup snapshots to another namespace I would use a sync-job, for moving retention rules you will...

Das ist der raidz-Aufschlag auf die refreservation. Schau dir mal die Faktoren an: 120G→162G, 350G→472G, 3,2T→4,32T, das ist bei allen drei Disks exakt 1,35. Kein Zufall. Bei einem thick provisioned zvol legt ZFS die refreservation so aus, dass...

UdoB reacted to patpat0's post in the thread Proxmox VE 7 is vulnerable to some type of 0day/RCE non auth with Like.
Purely theoretically, we don't know how long this bug has been exploited since it was possible to do anything, including clearing logs. Only now have script kiddies gotten their hands on it.

UdoB reacted to gfngfn256's post in the thread Proxmox VE 7 is vulnerable to some type of 0day/RCE non auth with Like.
Obviously this is possible, since anyone can compile the kernel as he sees fit. However, I do not believe that Proxmox VE or their community needs to invest time nor resources to maintain (extreme) EOL systems. I also believe Johannes S is...

UdoB replied to the thread New router, PVE host can't connect to network at all.I don't know the specific reason. But basically: (PCI-bus)- interface names are not stable. They may mutate on hardware changes and on the advent of new kernel modules. That's why "pinning" was introduced...

UdoB reacted to siren4161's post in the thread New router, PVE host can't connect to network at all with Like.
Oh gosh, I've found the error. My interface is actually eno2 but /etc/network/interfaces had eno1. It's working now. Thanks, all. I'd like to learn something here. Why would my interface name change in the process of carrying my host PC from one...
