Die 10W finde ich jetzt auch nicht stromsparend. Aber ja, besser als die Nachfolger ;)

The proper way to remove the "nag" is to pay for a subscription. I don't say removing it is as bad as pirating software. It's open source and you are allowed to patch the code according to licensing. But it's still not nice because you are compromising the financial model to not have to pay for...

I've seen staff helping no-subscription users and that patch wrote something like "Nag-patch applied" to the syslog when starting the server and that staff member wasn't amused to see this when reading through the logs to help that user with his problem...

Soweit wie ich das verstanden habe hebst du sämtliche Isolation zwischen den PCI(e) Geräten auf. NICs, Soundkarte, Disks, USB, GPU, ... alles was da irgendwie per DMA den RAM ließt/schreibt kann dann ggf. auf sensible Daten zugreifen. Ist dann halt ein weiterer offener Angriffsvektor...ob den...

Wenn nur vertrauenswürdige Personen auf deine VMs zugreifen, die nicht vorhaben dir zu schaden, nicht sonderlich. Richtig problematisch wird es wenn du z.B. VPS vermieten willst, dir eine VM gehackt wird und sich der Schaden dann noch auf weitere VMs erstreckt etc.

You can only destroy and recreate a smaller thin pool.

Bei der PLP geht es aber darum, dass dann deine SSD Faktor 100 oder so schneller bei Sync Writes ist. Das hast du nur mit SSDs mit eingebauter PLP, nicht bei einer consumer SSD an einem UPS.

Best way to not waste RAM is to not assign a VM more RAM than it needs. 4GB should be enough for OMV unless you use ZFS or similar. Otherwise it will eat all RAM you throw at it which then isn't available for other VMs which might benefit more from it.

Hi, I needed to replace the hardware of a cluster node. The old node was using proxmox-boot-tool (systemd boot, no secure boot) and ZFS for the root filesystem. The "new" hardware only supports legacy boot. I would prefer to reuse the old disks without reinstalling PVE. Did someone already...

And again: https://www.linuxatemyram.com For Linux VMs, PVE webUI will show RAM used for caching as "used" and won't show "available" RAM as "free" RAM.

Some servers don't use proprietary hardware and will have standardized connectors and E-ATX/ATX/uATX formfactor (I like those older supermicro boards). Combine those Server mainboards with ECC RDIMMs, Server CPU, Enterprise SSDs and some quiet ATX PSU, tower cooler and case and you have a...

One problem is TrueNAS support. If you got a problem and ask in the TrueNAS forums they will roll their eyes and tell you that TrueNAS should be run bare metal and that the only supported hypervisor is ESXi. I personally got some problems in the past with shutting down the VM where it gets stuck...

Those values probably aren't temperature in degree celsius but the "health" for that metric going drom 0 to 100 or reverse. See the "smartctl -a ..." output and have a look at the datasheet of the disk manufacturer in case there is one that explains how to interpret SMART attributes.

TrueNAS in a VM works fine. But you probably want a dedicated HBA card and disks for TrueNAS for PCI passthrough so TrueNAS is able to directly access the real physical drives. TrueNAS uses ZFS and ZFS is quite demanding (lots of RAM, ECC RAM, Enterprise SSDs with PLP, CMR HDDs, lots of CPU...

Ok, because adding or removing any PCIe device might change the network interface names causing the network configuration to fail and then not allowing you to access the webUI.

NVMe SSDs or additional HBA/raid controller added?

Your pool only knows "nvme-eui.000000000000000100a0752446a4a08c-part3". So try something like: "zpool attach -f rpool nvme-eui.000000000000000100a0752446a4a08c-part3 /dev/disk/by-id/nvme-INTEL_SSDPE2KX010T8_BTLJ908508XJ1P0FGN-part3"

Point it to the actual device: sgdisk /dev/disk/by-id/nvme-Micron_7450_MTFDKCB800TFS_240446A4A08C ...

Like already said, ticking the "discard" checkbox alone won't help. You will have to configure your Ubuntu to trim free space. You will have to edit your Ubuntus fstab and mount filesystems with the discard option or create a systemd service/cron job to run a "fstrim -a". Using the latter it...

In the PVE webUI, go to the hardware tab of every VM, edit each virtual disk there and check the "Discard" checkbox. In addition you need to tell each guestOS inside your VM to actually trim/discard. How to do this completely depends on the guestOS your VM is using. In a Linux guestOS you could...
