It turned out to be a massive undertaking, that I heavily underestimated, but I managed to compile Datacenter Manager for ARM64. This makes it possible to install it on devices like a Raspberry Pi and many others: ARM64 Packages... -
UdoB replied to the thread Additional Network configuration.Right. From pfSense's point of view. Basically "WAN" + "LAN" are just names. Plus some default rules created already for you - allow output through WAN w/ or w/o NAT, deny input at WAN. Also enable routing inside pfSense. If you label the...

Moin Eine sinnvolle RAM-Verteilung sehe dann so aus: 4 GB Proxmox VE 4 GB OMV VM 4 GB HA VM x GB Weiteres Ergo: Du brauchst noch mehr RAM. Eine Minimal-Lösung sehe dann z.B. so aus: 2 GB Proxmox VE 2 GB OMV VM 2 GB HA VM x GB Weiteres Dann...

Willst du rumspielen oder den Plex und HomeAssistant auch produktiv verwenden? Falls ersteres kannst du auf deiner alten Kiste mit ProxmoxVE herumspielen, falls zweiteres würde ich HASS auf dem pi belassen. Plex kann man auch aus einen Container...

UdoB replied to the thread Additional Network configuration.It is a different network --> reachable only with an active router and your working PC using that route. My answer does not directly solve your problem, sorry. Just use the other IP (.0.59) for setup, that does work, right? I recommend to...

Have a checkout of the https://github.com/Corsinvest/cv4pve-report tool. This to me is close to what RVTools in the VMware world gave. But +1 to adding the functionality inside the PVE GUI or PDM inventory views.

UdoB replied to the thread Richtiges Setup für Heimserver.Richtig! Dazu kommt noch: viele lesen "Container" und denken "Docker!". Wenn ich mit auf einem kleinen Rechner damit arbeiten will, ist PVE definitiv Overkill. Dazu genügt ein schlichtes Trixie und das mitgebrachte "Docker". (Oder notfalls das...

noch ein paar Gedanken: Unterstützt dein Celeron VT-x VT-d und wie gut? Falls nicht, kannst du das Zeug für den avisierten PVE-Zweck entsorgen. Dann tatsächlich lieber OMV mit Docker-Erweiterung RAID würde ich mir sparen, das bringt gerne...

Naja für virtuelle Maschinen eignet sich der Host natūrlich nicht wirklich, aber Container gängen schon. Würde dann aber auch eher omv plus docker-Container nehmen

If you’re using an IPSec VPN, you are encapsulating Ethernet packets over whatever link you have. If your IPSec goes over a link with 1500MTU, your IPSec header takes about 60 bytes if I’m not mistaken, then your Ethernet packets need to be...

UdoB replied to the thread Richtiges Setup für Heimserver.Ich bin definitiv ein Proxmox PVE Fan. Aber damit: würde ich eher OMV (oder ähnliches) direkt installieren. PVE bringt notgedrungen Overhead...

Like.
That's for file systems (OS/CT) and shouldn't affect ZVOLs. I guess you meant to set volblocksize=16k (which is default) instead? That said I'd leave both properties alone/default and set the ZVOL part via Datacenter > Storage if needed. Check... -

Spent the weekend benchmarking both on the actual hardware before committing. Sharing the results. Setup: 4x 2TB Samsung PM9A3 (enterprise NVMe, PLP), AMD EPYC, 128GB RAM. LVM-thin on mdadm RAID10: - Sequential read: ~12 GB/s - Sequential...

Actually, you can easily "get around the physics" of hard drives by using caching/tiering, which we've had for decades on RAID controllers and SANs alike. It's not something FOSS has made a priority in recent years, although there is the special...

The main bottleneck with hard drives is that they’re relatively slow. So ~100 IOPS peak and maybe 5-10MB/s in random read write scenarios. You need to read/write 100TB/day -> 1200MB/sec -> you need 300 disks just to keep up multiplied by the...

I would not be comfortable at all with this single server and single array setup for people doing real work. Why not at least get a second system and do ZFS replication? What are you using for backups and how frequently? Side comment...

UdoB reacted to J-Rod's post in the thread Are refurbished laptops reliable enough for a small Proxmox VE homelab? with Like.
I also would not recommend buying a laptop for PVE. If you had a spare one sitting around and wanted to play, then sure, but spending money in this direction is not ideal due to expandability limitations. However, for similar reasons I would...

How is this related to the hardware's reliability? I don't really see a good reason to use a laptop here. Seems a whole lot more expensive than a used office PC as well.

I would have second thoughts about SSD life, because with ZFS, you might end up having problems with the usual consumer-grade pre-used SSDs that are built into those laptops. Also, RAM tends to be soldered, so you probably cannot extend that, either.

You could also used used mini-pcs which where aimed for usage in office environments. Since they are (more or less, at least with Lenovos ThinkCentres and Dells Optiplex) based on mobile technology (think notebooks without display ;) they are...
