Like.
For replication clustering isn't actually needed since you could also use pve-sync for it. The story is different for high-availability though, that feature needs a cluster. Only @SInisterPisces know whether he needs it or not though ;) One... -

The main advantage I see of having two PVE servers in the same cluster is that you can easily set up and manage replication between the hosts using the PVE GUI. When you need to do maintenance to one of the servers, you can hot migrate all of...

Usually but why not test it in a virtual PVE? :)

UdoB replied to the thread PBS on RAIDZ2+HDD, no special file.This is only HDD, zero SSD. (As of #1) Having a "separate" Special Device on the very same spindles makes no sense. Actually we know not much at all. What actual drives are available? How many? How many (unused) connectors has the controller...

UdoB replied to the thread [SOLVED] [Virtualizing PDM] Host PVE Node Uses ZFS Storage. When installing PDM inside VM, EXT4 or ZFS?.That's interesting. Basically it's a great example of having the same information as everybody and coming to the exact opposite conclusion. While personally I would not go that road: if it works for you, it is fine! :-) (( It may depend on...

Die Swap-Frage aus #16 ist hier irgendwie untergegangen: ja, auf die 256er ist genau richtig. Swap als zvol im rpool kann dir unter RAM-Druck den Host einfrieren (Kernel will swappen, ZFS braucht dafür selbst RAM), deshalb legt der Installer bei...

Einen Wireguard Server (egal ob nativ, mit OpenWRT oder OPNsene) zu konfigurieren UND das ganze in die PVE Network config einzuarbeiten ist nicht ganz trivial. Man kann alles machen, wenn man die nötigen Kenntnisse hat... das eignet mansich auch...
-
Bei Host vs. LXC noch ein Punkt: wenn WireGuard im Container läuft, hat der Host selbst gar keine WG-IP, an die sich pveproxy überhaupt binden könnte. Du müsstest den Kram dann per Routing/NAT aus dem LXC zum Host schaufeln, und die...

UdoB reacted to Johannes S's post in the thread [SOLVED] [Virtualizing PDM] Host PVE Node Uses ZFS Storage. When installing PDM inside VM, EXT4 or ZFS? with Like.
It was a typo, I corrected. Thanks for the hint ;) I meant that ext4 is more robust than xfs e.g. in case of a power failure while xfs is said to perform better with databases and similiar workloads. Another difference is, that ext4 can shrink...

UdoB replied to the thread [SOLVED] [Virtualizing PDM] Host PVE Node Uses ZFS Storage. When installing PDM inside VM, EXT4 or ZFS?.Yeah, that's fine as long it is useful inside of the VM For pure testing it it fine - as there are definitely other rules than for a productive system. I am sure you know the recommendation to pass-through a controller for this, before going...

It really depends on the usecase. For example for OPNsense ( see https://forum.opnsense.org/index.php?topic=44159.0 by meyergru ) it makes sense to use zfs inside the vm to have snapshots and due to the relative low write amount of opnsense the...

This is not possible with Hetzner storage box though If I recall correctly. It might be possible to limit it to a hetzner vserver but then the vserver costs outweighs the price benefit of the storage box. Using storage boxes ( or any other...

UdoB reacted to TErxleben's post in the thread Neuinstallation mit ZFS: verschiedene Größenangaben with Like.
Ich würde es so handhaben, da selbst bei fest eingebauter Platte erheblich bessere Portabilität gegeben ist. Beim Umbau muss das Zielsystem sonst zwingend über ZFS-Fähigkeiten verfügen und es muss diesbezügliches Knowhow vorhanden sein. Gerade...

UdoB replied to the thread Neuinstallation mit ZFS: verschiedene Größenangaben.Kann man machen und ich werde dir das nicht auszureden versuchen. Ich verwende lieber ZFS, aus den bereits dargelegten Gründen.

UdoB replied to the thread [SOLVED] [Virtualizing PDM] Host PVE Node Uses ZFS Storage. When installing PDM inside VM, EXT4 or ZFS?.Sorry, I don't have any current pointers. But the concept of the unwanted, massive write-amplification is still true, right? There were some "historical" misunderstandings and there are some newer improvements, yes. But "consumer SSDs" are...

UdoB replied to the thread Neuinstallation mit ZFS: verschiedene Größenangaben.Okay. Wenn ich gezwungen wäre, mit den vier Geräten aus #1 zu arbeiten, würde ich: die beiden 2 TB NVMe + SSD als Mirror vorsehen und darauf PVE installieren. "rpool" ist dann groß und kann max. eineinhalb TB Nutzdaten aufnehmen. Das Resultat...

UdoB replied to the thread Neuinstallation mit ZFS: verschiedene Größenangaben.Auch wenn ich gerade das zitiere, ich verzichte mal auf eine passende Antwort - mein Standpunkt ist ja klar ;-) Vermutlich liegt "die beste Lösung"™ mal wieder in einem Kompromiss: für das Funktionieren des System wichtige Teile sollten...

Hi, for a 3 node PVE cluster with integrated shared (VM) Storage + HA the following options are feasible. - Ceph (HCI) - ZFS replication between the 3 nodes - but be aware it's async - data loss is possible - 3rd party SW/plugins like...
