Geht mal zur Liste der Backups und selektiere eine konkrete Sicherung, durch anklicken. Oben in der Button-Reihe gibt es einen Knopf "Show Configuration". Ein Container in meinem Cluster zeigt mir dort... die Konfiguration an, die zum Zeitpunkt der Sicherung aktiv war. Insbesondere enthält sie...

I've often said that I am a ZFS fan. But hey, this is not the Butlerian Jihad with "filesystems" as the topic. The system I am using in this very moment has a normal ext4 filesystem :-)

The point is: you can not know that. Of course you are free to use any available technology you want - and a lot of installations are using hardware Raid (edit: ... without a checksumming filesystem). No fight here; if it works for you/them, then I am fine too ;-)

For me reliability comes first, performance is second. If you do not use ZFS you'll lose some really great features which are important for me: https://forum.proxmox.com/threads/fabu-this-is-just-a-small-setup-with-limited-resources-and-only-a-few-disks-should-i-use-zfs-at-all.160037/ But of...

Looks complicated :-( The last scrub was on 12. April. The problem occurred before that date? If not: try again...?

This does not match my own observations. (With a small sample size and w/o an explicit test. I just see cheap devices dying with a much higher frequency rate than expensive ones, specifically with PLP - and specifically in the PVE context.) Do you have a link to the actual test/study?

I cannot answer that as "it depends", sorry. On all of my PVEs the host handles (local) storage, exclusively. In my Homelab the largest storage (in the cluster) is served by an LXC container (not: VM) to some clients. The host owns the storage and backup and management is handled there. ( -->...

Correct. That's another thing I would never do or recommend :-) (( With one single exception from my personal point of view: teaching/learning/testing/debugging. I have a virtual cluster with six "hosts" = zfs-on-zfs. It works surprisingly well without production load. That's in my homelab...

Now you have the basis to compare both systems ;-)

I did not recommend it. But if I would have to create a virtual TrueNAS (I don't) then this is a requirement...

In the Login dialog there is a drop-down menu to choose the "Realm". Any chance to took the wrong one?

You should always pass-through a controller, never disks. Background, while old still valid: https://www.truenas.com/community/resources/absolutely-must-virtualize-truenas-a-guide-to-not-completely-losing-your-data.212/

Please post the content of /etc/network/interfaces "nic0" is DOWN - usually this means that it has to connection to a switch. Check that cable; look for LEDs showing "Link" established - on both ends. Use another cable if that fails. ... ...

Please add some system description like which OS you are using - and add a screenshot. If you have a Display Scaling mechanism activated please try to disable that one by setting it to "100 percent" - first only in the OS and then only in the browser! And/or try a different resolution. This is...

Nur direkt am Gerät, nicht remote. (Es sei denn per iDRAC/IPMI/KVMxyz, sofern vorhanden.) Direkt nach dem Einschalten einfach den Cursor auf/ab tippen, das ist unschädlich. Am Ende sollte das Grub-Menu sichtbar sein - mit "Proxmox VE GNU/Linux" + "Advanced options ...". Da der "Recovery Mode"...

Well.., without more details it is difficult to say something. There should be a boot menu before that message. There should be a "boot previous kernel" option. Please post more details...

Are you sure that nic0 is the correct network interface and it is actually connected? It is listed as "state UNKNOWN" in the last screenshot. If you actually have three NICs just try the other two. You need to get "state UP" for both the bridge and the corresponding NIC. After editing...

Yes, OpnSense/pfSense are complex beasts. Just look at the loooong feature list! Compared with that Wireguard is really, really easy - as it does one single job, and it does it right! My preferred method is to handcraft something like https://www.wireguard.com/quickstart/. This requires one...

The full setup needs some complexity, to be useful - right? To examine routers and network problems you may setup a virtual playground. When I wanted to play with Ceph I took one beefy PVE node and created six virtual PVE nodes, created a cluster, prepared several virtual disks for Ceph...
