    Iirc WD20EFAX are SMR ("Shingled ..."). It is really a game of luck to make them work with ZFS. (Read https://www.truenas.com/docs/hardware/notices/wdsmr/ ) Problems especially during resilvering are somewhat... expected.

    Gibt es einen Grund, nicht alles per Hardware-Raid oder eben alles per ZFS aufzubauen?

    Das ist doch genau der richtige Ausgangspunkt - eine Testkiste zum spielen, kaputtmachen und ausprobieren inkl. Desaster Recovery! Also learning by doing! Ich bevorzuge Hardware-Raid (je nach Controller), nutze aber kein ZFS sondern lieber ext4...

    Just as a bad designed example: one single pool, RaidZ2, three devices for the Special Device because two were not stable - and one being attached by USB. Again: bad design. What I can see here is this: root@pvec:~# zpool iostat -v 5...

    Seems so; it's great that it works fine for you! That's why I very often emphasize "my context"... :-)
  • UdoB
    Not what I am seeing in the real world. Let's start with a fresh VM where nothing is already backed up: zpool iostat poolBackup 1 capacity operations bandwidth pool alloc free read write read write...

    UdoB replied to the thread Hardwarer oder Software RAID.
    Da kann man durchaus drüber diskutieren, spätestens seit der Erfindung von ZFS :-) Ein Hardware-Raid liefert NICHT: Herstellerunabhängigkeit; transparente Kompression; garantierte Integrität; (technisch) billige Snapshots; Replikation; einfache...

    There’s an option to back up all VMs on a node.
  • UdoB
    Yes... I did mention that. But arming/disarming HA is _not_ the same thing as putting one node into maintenance mode - the latter function serves a completely different purpose.
  • UdoB
    Well..., I have two buttons at the top of the "Datacenters" --> "HA" screen: "Arm HA" and "Disarm HA" (Freeze/Ignore-dropdown).

    Have it running on a Dell R200 which was released back in 2007. Was running LXCs but now it's a PBS instance. Mirrored ZFS drives. Makes for good small LXC/PBS server but that's all it's good for.
  • UdoB
    Pulling a case of Godwins law won't make me take you more seriously. In the case of Proxmox it's quite laughable since they have a decades old track record of NOT outselling. One Proxmox developer ( I think @t.lamprecht but I might be wrong)...
  • UdoB
    Yes, otherwise I wouldn't have used it ;) Correct, I'm also not paying for Proxmox. But I also don't expect developers to give freebies to me. I'm trying to help in other terms, e.g. by participating in the forum or being a free beta tester ;)...

    PBS does really, really do random writes. It needs IOPS - as many as it can get. For ZFS there is the rising problem of fragmentation of the free space --> it is not guaranteed that a single 2-4 MB chunk can be written sequentially at one...
  • UdoB
    There are many, many posts written about a good setup. My personal key-points (in a very small nutshell) are these: PBS must be self-contained, on separate hardware; especially when you have only one PVE (no cluster) you want to have access to...
  • UdoB
    Great! My own one was decommissioned last year. Finally, after (nearly) 15 years. Basically because I have much better gear for PVE now... and PBS is really hard to make it fly on such an old thing. Have fun!
  • UdoB
    Hey man, as today, i'm running one of this in my homelab (3 node cluster)! Yesterday i update to pve9 - i'm happy with this ultra-low energy choice. BTW, works for me too! ;)
  • UdoB
    Don't run 'apt upgrade' as it might not pull in all dependencies; use the official instructions instead: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#system_software_updates And here is a (another) recent thread where the same problem...
  • UdoB
    If you don't like the nag screen and don't want to contribute to the development ( guess what developers need to pay bills too ) there is an easy fix: Don't use the software. For cross-cluster migration you can also use the pct remote-migrate and...

    Hey zusammen, gerne möchte ich (einige kennen mich sicherlich bereits von ProxLB, PegaProx und den Ansible Modulen für PVE) euch auf das Community-Event Proxday 2026 aufmerksam machen, der von der credativ GmbH veranstaltet wird. Das Konzept ist...
