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...

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...

Can you please add this to the referenced bugzilla entries?

We implemented our own retry logic for PBS restores, and now the issue is fixed. I think it would be beneficial for devs to implement retry logic on GET requests for chunks, with an env variable for how many retries.

You can configure a put-rate-limit with the cli tool: https://pbs.proxmox.com/docs/command-syntax.html#proxmox-backup-client Or by editing the config file see...

UdoB replied to the thread How to add new disk to ZFS pool?.You can run zpool upgrade without(!!) a poolname to get a list of new feature flags.

UdoB replied to the thread LVM-thin vs ZFS for local VM storage on a single-node PVE — pros/cons in 2026?.That one was always overhyped. Today ZFS works with a very few GB of Ram, capped at 16 GiB on a PVE installation: https://pve.proxmox.com/wiki/ZFS_on_Linux#sysadmin_zfs_limit_memory_usage This one is true. And @LnxBil hit the nail: " Not using...
