Würde ich nicht machen. Performance ist echt nicht toll wenn deine VMs/LXCs von HDDs laufen. Auch nicht vergessen, dass ein Raid5 echt nicht toll für VMs/LXCs ist. 6 Disks im Raid5 sind von den IOPS her so lahm wie eine einzelne Disk und bei ZFS wärst du auch gezwungen deine Blockgröße...

Yes, and the great thing about it is that you can adjust to a newer PVE version or new hardware. Where a deploy script made for PVE 8 maybe won't work with PVE9 anymore without spending a lot of time keeping your redeploy scripts always updated. I've got a DokuWiki container for this where I...

TrueNAS got a minimum RAM requirement of 8GB. PVE 2GB. So with that single VM alone you should have like 11+GB of RAM. And TrueNAS uses ZFS, so consumer SSDs aren't great and I would bet you didn't bought a proper SSD with power-loss protection. ZFS also benefits from ECC RAM your MiniPC...

Wüsste ich jetzt nicht. Du musst dir halt überlegen was ein VLAN Interface macht und wie da die einzelnen Pakete durch den PVE laufen. Also wann da an welchem Schritt die Pakete getaggt werden und wann der Tag wieder entfernt wird.

Nein, du mischt das. Entweder VLAN interface unterhalb einer vlan-unaware Bridge oder ein VLAN interface oberhalb einer vlan-aware Bridge. Also entweder... auto lo iface lo inet loopback auto eno1 iface eno1 inet manual auto eno1.3 iface eno1.3 inet manual auto vmbr0 iface vmbr0 inet manual...

I like all my disks mirrored via software raid and with checksumming. The only other supported option would be btrfs and thats still in "feature preview" state, less mature and got other problems. The unsupported mdadm works but got problems too (like the bug you linked above). Encryption on PVE...

But that's a very advanced topic. Debian Installer isn't supporting ZFS and PVE installer insn't supporting LUKS. From what I've read so far full system encryption using ZFS on LUKS is full of pittfalls and has all to be done manually via CLI from a Live Linux after installing an unencrypted...

You could install a Debian 12 using the installer of the Debian 12 ISO. That installer supports LUKS while the PVE installer does not. For the raid0 you could use mdadm + LVM that the Debian installer is supporting. You then could install the PVE packages on top of that encrypted Debian 12...

You only need a single vlan-aware bridge. For a VM in multi vlans you got two options: 1.) a single vNIC and you don't set a "VLAN Tag" in the vNICs settings. In this case the guestOS got access to all vlans on that bridge and vlan config has to be done inside the guestOS. 2.) you create one...

There is an example: https://pve.proxmox.com/wiki/Network_Configuration#sysadmin_network_vlan I would use a single vlan-aware bridge. Then add a vlan interface on top of that bridge for your management. VLANs for VMs are tagged in the "hardware" section of your VM config when editing the...

You know that your "Min RAM: 4 GiB" config could force TrueNAS down to 4GiB of RAM and that TrueNAS got a minimum hardware requirement of 8GB?

It gets especially bad when a scrub is running in parallel. Not that unusual here that a weekly re-verify task will then run for 10 hours to verify a fraction of the 2TB datastore on a 4-HDD raidz1 + special device SSD mirror. Don't want to know how slow that would be scrubbing and re-verifying...

Also keep the time, needed for resilvering, in mind. Once one of those 8x8TB disks in a raidz1 dies you will have to replace it and resilvering might take some days where your other disks are tortured 24/7 with 100% IO. In that state ZFS can't fix any errors any longer and it is very likely that...

It's one of the few backup solutions that makes heavy use of deduplication instead of more classic approaches like differential backups. With those differential or full backups the IO is pretty sequential but deduplication causes stuff to be scattered across the disk with lots of references...

You don't need to mirror your read cache. If you are paranoid you could mirror that SLOG in case that SLOG SSD could be failing on an power outage.

Bei richtigen Servern würde man für sowas das webKVM vom BMC benutzen. Dann kann man den PVE Server von jedem Ort der Welt über den Browser starten/ausschalten/konsole bedienen und muss nicht mehr selbst ran außer natürlich man muss Hardware austauschen. Für Consumer Hardware lässt sowas auch...

You can add a special device later (but not remove it without destroying the pool). But old metadata will still be stored on those HDDs and ZFS can't move that metadata to the special device SSDs. You will have to remove and add all your data again (or move files between datasets) for the...

There is no magic you can do to make it fast. PBS simply needs IOPS performance and HDDs can't deliver those. You either need as many small HDDs as possible striped in a raid10 or even better a few big SSDs. A traditional raid5 got single disk IOPS performance as well. So think of it like using...

Ich synce hier alle Backups. Alles was auf PBS VM A auf PVE Node A gesichert wird synct sich auch zu PBS VM B auf Node B rüber und anders herum. PBS Backups hat man am besten immer auf zwei Datastores, weil wenn du einen Chunk verlierst ist nicht nur ein Backup Snapshot weg sondern mit Pech ALLE...

That is L2ARC that consumes RAM, not the SLOG. All sync writes are written to RAM + disk anyway. Difference is that without a SLOG the sync writes will be written to the ZIL on your data disks instead of a dedicated disk for it.
