Ich upgrade regelmäßig PVE in Unternehmen wo es keine Unterbrechungen geben darf. Solange man die Anleitung befolgt und Warnmeldungen auch beachtet / abarbeitet und nicht ignoriert ist noch nie etwas schief gegangen. Die Kunst ist das lesen, wer... -

Was ist daran doof? Warum bitte sollten die Entwickler weiter Updates bereitstellen, weil Leute zu faul zum updaten sind? Das Basisystem von Debian kriegt ja eh schon keine Updates mehr, das heißt also die Entwickler müssten den Aufwand für...

this is true, but have you ever implemented it? its slow as molasses. mdadm parity raid... brrr. THAT is brave. also, there is no "self healing" of any kind. This has the same problems as a HA zfs filer. the only "upside" is that you dont have...

UdoB replied to the thread PBS on RAIDZ2+HDD, no special file.Without an SD all metadata is stored on the HDDs. To read it, the head has to move physically. That takes some milliseconds. As all data (including meta-data) is equally distributed on the whole device this repeats often. Unfortunately I have...

It helps a bit but not much compared to a Special device on a ssd mirror. You could do some Benchmark to get data instead of guessing.

Damit bist du gut aufgestellt, mehr braucht's da nicht. Vorher würde ich noch einmal eine kleine VM testweise aus dem NAS-Backup zurückspielen (neue VMID, dann kannst du nix kaputt machen). Klingt übervorsichtig, aber ein Backup das noch nie...

Ich weiß du kannst nichts dafür, aber Blödsinn und nutzloses Compilance-Theater bleibt Blödsinn, auch wenn das mit kritischer Infrastruktur begründet wird. Könnte aber erklären, warum ganze Krankenhäuser durch Citrix-Lücken o.ä. sich von der...

Not uncommon, but fraught. I've seen effort to make a HA ZFS filer solution for AT LEAST 20 years. There are 3 commercial solutions I'm aware of (Truenas/Nexenta/Intelliflash) but all three have either migrated/migrating to a different method of...

UdoB replied to the thread Unterstützung für Proxmox VE 8 endet am 2026-08-31.Nur der Vollständigkeit halber, weil es bisher nicht erwähnt wurde: https://pve.proxmox.com/wiki/Upgrade_from_8_to_9 ...beschreibt das Vorgehen sehr detailliert :-)

This should (at least in theory) take care, that nothing bad happens ( @scyto has a similiar setup he described here: https://forum.proxmox.com/threads/pbs-on-truenas-have-your-cake-and-eat-it-too.162860/post-770825 ) . The question is why...

UdoB reacted to Johannes S's post in the thread Opt-in Linux 6.14 Kernel for Proxmox VE 8 available on test & no-subscription with Like.
If they are core services, they are not isolated. There were already security issues in the past which allowed attackers to break out from vms to the host. I don't see any reason why related issues shouldn't appear in the future. Normally they...

UdoB replied to the thread ZFS on SAN LUN(s).Oh, sorry, I can't leave that sentence uncommented because of "similar features" ;-) Comparing LVM with ZFS easy. The result is easy too: they only have "logical volume"-management in common. Everything else is different! Specifically LVM does...

Why do you want to have ProxmoxVE on a workstation? If you don't happen to be a Proxmox developer (see: https://pve.proxmox.com/wiki/Developer_Workstations_with_Proxmox_VE_and_X11 ) ProxmoxVE isn't really suited to be a daily-driver Desktop OS...
-
UdoB replied to the thread ZFS on SAN LUN(s).Okay, I must admit I do not know much about that scenario - I've never tried to build such a thing. But I am fairly sure that there are more pitfalls than a new user (and me too) may expect to be present. That's why I wrote "... brave". Not...

Are you using Ceph 20.2.x as EC got major improvement with 20.2.x ? If you are mixing drives, expect the storage to be as "fast" as the slowest disk. Maybe instead of mixing disks you could create different pools with different crush rules...

Are you sure about the EC? I would expect EC to be slower than replica
-
UdoB replied to the thread ZFS on SAN LUN(s).Well, https://pve.proxmox.com/pve-docs/chapter-pvesm.html#_storage_types lists it explicitly as "ZFS (local)"! ZFS wants to have direct access to the hardware of the devices. This has been discussed multiple times for "pass-through disks or a...

UdoB reacted to uzumo's post in the thread ZFS dedup on a Proxmox host in 2026 — has fast dedup changed the recommendation? with Like.
If you're worried about memory usage or the fact that you can't turn it off, this would probably make you happy when it comes out. When multiple methods for deduplication emerge, it becomes unclear whether the term “ZFS deduplication” refers to...

UdoB reacted to aureladmin's post in the thread [TUTORIAL] HiveStation - Developer Workstation for Proxmox Virtual Environment with Like.
HiveStation V21.3.5 - fixes since 21.3.1 V21.3.5 is out. Archive attached: HIVESTATION-V21-COMPLETE.tar.gz. Existing installs move up with hivestation-upgrade.sh as usual; 21.3.2, 21.3.3 and 21.3.4 were never released, so this build carries all...
