Like.
Yeah, server and storage hardware, software and configuration details, including VM configuration would be nice to have to try reproducing this. -
UdoB reacted to pbanuelos's post in the thread Opt-in Linux 7.0 Kernel for Proxmox VE 9 available with Like.
Thanks team, despite being my first message I've been a Proxmox user for some years already. Upgraded and working flawlessly on a Minisforum MS-01:

UdoB replied to the thread pve 9.1.1 - Developer Workstation: shared folder & clipboard.Ich bin nicht der OP, aber ich antworte dennoch mal..., nur zu Unterhaltungszwecken... Naja..., warum nicht so arbeiten? Ich verwende PVE extensiv an mehreren Stellen, in meinem Keller läuft ein (total oversized) Cluster. Mit den üblichen...

UdoB reacted to mm3923's post in the thread RAIDZ2 with 6x 480GB SSD only 1.35TB usable total with Like.
Hello Udo, Thank you very much for the explanation. I use the datastore for VMs only; static data is stored on a NAS with HDDs. From this, I conclude that I should probably use RAID10 (i.e. 6x mirror vdevs) for performance reasons as well...

UdoB replied to the thread Significant IOPS Drop in Proxmox 9.1.9 VMs Compared to Other Hypervisors.You did not say anything of the underlying filesystems...? For ZFS it may be expected as ZFS does a lot more work than classic filesystems under the hood, resulting in multiple IO-operations used for metadata etc...

The deprecation itself was not strongly influenced by that, but the decision to communicate it more actively was in fact primarily driven by it. Normally, we only mentioned it on the side once a new kernel became the default. In the past, we...

UdoB replied to the thread RAIDZ2 with 6x 480GB SSD only 1.35TB usable total.Well..., it is "50%" versus "66%". For this 16% more space you lose two third of available IOPS. Six mirrors have three times the IOPS as two RaidZ2 offer, every single vdev counts. If you are storing VMs on the resulting pool then this is...

UdoB replied to the thread RAIDZ2 with 6x 480GB SSD only 1.35TB usable total.There was or there is an error in capacity reporting. I have no link, but the main point was that "more capacity" was actually present but just not reflected by the displayed values. As you found your solution by recreating the pool you may...

UdoB reacted to daanw's post in the thread RAIDZ2 with 6x 480GB SSD only 1.35TB usable total with Like.
After expanding the RAIDZ2 you need to rewrite the data so it can use the new parity ratio of 2:4 instead of 2:2. See: https://openzfs.org/w/images/6/68/RAIDZ_Expansion_v2.pdf and...

UdoB replied to the thread Stockage Type.Raid10 it is, multiple mirrors of two disks. Plus regularly (usually daily) backups, of course.

UdoB reacted to leesteken's post in the thread [SOLVED] zfs zpool not showing in webUI, but fine in shell with Like.
Proxmox does not automatically check for filesystems (that you create using command-line tools or otherwise). Go to Datacenter -> Storage and click Add and then ZFS. There you can select your new ZFS pool and give it a name and tell PVE how you...

UdoB reacted to Impact's post in the thread [SOLVED] zfs zpool not showing in webUI, but fine in shell with Like.
It should actually show up in node > Disks > ZFS. I'd recommend you enable the Thin provision option when adding it as storage. It's named a bit counter intuitive but it affect the refreservation property preventing you from over-allocating...

Or install needrestart, which also checks for services which needs to be restarted.

You can know this if /run/reboot-required exists. Usually only when a new kernel was installed. See: https://forum.proxmox.com/threads/on-package-updates-how-do-you-know-when-a-reboot-is-required.156352/

UdoB reacted to bbgeek17's post in the thread Hardware sizing guidance for Proxmox production cluster with Like.
Hi Nadee, This is a pretty common design pattern we see for production Proxmox clusters at scale for folks coming from VMware. The good news is that what you're describing is absolutely achievable. That said, before anyone can give you truly...

Obligatory reminder regarding Ceph: https://forum.proxmox.com/threads/fabu-can-i-use-ceph-in-a-_very_-small-cluster.159671/ Please note, that Udos Writeup is a little extreme since he assumes, that you want to survive the outage of two nodes...

UdoB reacted to woma's post in the thread Moving from 3-node full-mesh SDN to a 6-node using switches with Like.
Hi Patrick, Because new and old machines are same numbers you will have resources to temporarily run all guests only using new machines, so my safe and boring approach would be: build new 3 node cluster connected to switches setup up and test...
