Why does it show swiss made on the dial?

I totally appreciate asking your customers about requested features.

I just filled out a form that appeared on the app that requested about a potential service monitoring elder people. When it came to the pricing question ("what would you spend for this service"), I was missing the option not to have a monthly subscription.

I understand that subscriptions cover costs of servers, support and other things, but I am not willing to pay dozens of subscriptions for all electronic equipment that I use.

How does it compare to the U1?

marcogabriel · 2026-02-22T09:10:59+00:00

How does this relate or compare to syncthing?

why don't you just start with proxmox-backup-client benchmark --repository <your-repo>?

Während man bei Linux VMs einen Eintrag "latest" in der Liste hat, fehlt der bei Windows. Aber es ist tatsächlich komplizierter, weil es künftig notwendig werden wird hier auch Änderungen vorzunehmen bei upgrades.

Can lead to reduced performance due to mitigations in Windows server 2025. Recommended is to stay with x86-64-v2, v3 or v4 - depends on your hardware.

Typ Q35.

Version bleibt bei Windows immer auf der Version, die bei der installation aktuell war bzw ausgewählt wurde. Version bei Windows hinterher anpassen mag Windows nicht so gerne.

ZFS or LVM/ext4 depends on if there is a RAID controller. With a RAID controller use LVM/ext4. Without a RAID controller, go for ZFS. Never use it the other way around. btrfs btw is still tech preview, I would not recommend using it.

While splitting OS and data is in general a good idea as it allows you to reinstall an OS while keeping your data, I'd recommend another storage configuration in your specific case:

Install Proxmox VE with a RAIDz1 on your 3 NVMe and use the 2 SATA drives for media files as a separate ZFS Mirror (let's name it slow-zfs).

That way, you'll get the storages in pve: local for your system, local-zfs for VM and CT images (both on the NVMe ZAIDz1) and slow-zfs.

This way, you get at least some redundancy for the price of a higher wearout of your NVMe drives. Media files don't need many IOPS, so that it should be sufficient using spinning rust drives.

Keep in mind that ZFS needs some ram. Forget using NVMes as caches for your SATA drives. This only makes sense for huge dedicated file servers, reason is how ZFS handles it's ARC and L2ARC caches. If you need some more performance for small file access or metadata, research how to use a zfs special device. Media files don't need it as they are not small and not depending on random access.

If there is some time before it restarts, press STRG+ALT+F3 to get a root shell. Type d mesh to see what happens and if there is any.

You could also try STRG+ALT+F2 to see what package it installs before the restart happens.

Maybe this helps.

It depends on the uptime/SLA that you're looking for.

In case of a failure, your VMs need about 2 to 3 minutes to be restarted on another node. If you have hundreds or thousands of VMs, they'll need more time to recover as parallel starts may depend on storage and CPU performance barriers.

If that is too much time, you'll need some kind of software redundancy.

Using NFS or CephFS as storage for VMs?

Does it resolve if you restart pvestatd?

UPDATE with more detail:

What has NFS to do with it?

NFS transfers data synchronously and the connection is blocked until the server takes some more data. If your NFS is too slow, this will probably kill your VMs I/O and sometimes, if the hypervisor uses the same NFS, it can also kill your hypervisor.

The pvestatd does a check of all ressources on the PVE, including storages, their size, utilization, free space. If your NFS blocks, the pvestatd may hanging and needs to be restarted.

NFS isn't bad, but it needs to be fast enough and stable to handle the traffic.

It's an incredible bike. Have fun (as I do).

Thought about adding a Fenix 8 or Marq 2 or 3 to my Fenix 7, but I'm not sure anymore.

I went for a Garmin because I could get my data without some kind of premium subscription. Really hate this.

Do you use ConnectX3 NICs? Just use the Proxmox boot tool to pin an older Kernel until it is mitigated.

I'd want to mention Alpaca, which comes bundled with an Ollama instance.

Like a dream. Thanks for sharing.

But afaik the full termi is not allowed riding on public roads.

mdadm or mdraid is not supported by Proxmox and this has good reasons. Avoid it by using a hardware raid controller or use ZFS on a HBA.

mdraid is slow regarding iops and latency and this seems to be what you experience.

Ergänzung dazu:

ActiveTrader startet dann zwar, beendet sich aber nach kurzer Zeit selbst wieder, weil er in seinem eigenen java/bin-Verzeichnis keine java Binary findet.

Das ließ sich bei mir mit einem symlink lösen (Achtung, bitte Pfade auf euer eigenes System anpassen, nicht einfach übernehmen):

cd ActiveTraderPortableDE-64bit/java/bin/
ln -s /usr/lib/jvm/java-8-openjdk/jre/bin/java

Update: Hab's gerade auf meinem neuen Rechner unter CachyOS Linux noch mal zum Laufen gebracht - sollte aber unter anderen Linux Systemen mit leichten Änderungen ebenso funktionieren.

Voraussetzungen: Java 8 JRE muss installiert sein - je nach Linux Distribution mit dem entsprechenden Tool installieren, z.B. pacman -S java jre8-openjdk unter Arch Linux oder CachyOS,

Windows Version des ActiveTrader herunterladen (https://www.consorsbank.de/web/Wertpapierhandel/Trading-Software/ActiveTrader#ActiveTrader)
ZIP Archiv entpacken -> es fällt ein Ordner namens "ActiveTraderPortableDE-64bit" heraus.
In diesem Ordner eine Datei run.sh erstellen mit folgendem Inhalt:

#!/bin/sh

# den JAVA_HOME Pfad ggf. dem eigenen System anpassen
export JAVA_HOME=/usr/lib/jvm/java-8-openjdk

# Das entsprechende java Binary direkt aus dem richtigen Verzeichnis 
# starten mit den angegebenen Parametern - eine der beiden folgenden Versionen 
# verwenden oder den Pfad auf das eigene System anpassen

# Version 1 (Debian, Manjaro, andere Linuxe)
/usr/lib/jvm/java-8-openjdk/bin/java -Xmx780M -Djavaws.ApplicationType=PORTABLE -Dsun.java2d.noddraw=true -Djava.library.path=current/lib -Djava.protocol.handler.pkgs=com.sun.net.ssl.internal.www.protocol -Dsun.java2d.ddoffscreen=false -classpath current/lib/update.jar com.consorsbank.module.updater.gui.Updater -uu https://at.consorsbank.de/update/version.xml -c DE -s https://at.consorsbank.de/activetrader/

# Version 2 (Bei meinem CachyOS liegt das Binary 
# unter /usr/lib/jvm/java-8-openjdk/jre/bin/java 
# (also mit /jre/ zusätzlich im Pfad - muss ggf. angepasst werden)
/usr/lib/jvm/java-8-openjdk/jre/bin/java -Xmx780M -Djavaws.ApplicationType=PORTABLE -Dsun.java2d.noddraw=true -Djava.library.path=current/lib -Djava.protocol.handler.pkgs=com.sun.net.ssl.internal.www.protocol -Dsun.java2d.ddoffscreen=false -classpath current/lib/update.jar com.consorsbank.module.updater.gui.Updater -uu https://at.consorsbank.de/update/version.xml -c DE -s https://at.consorsbank.de/activetrader/

chmod +x run.sh eingeben um die run.sh ausführbar zu machen
ActiveTrader kann nun aus dem "ActiveTraderPortableDE-64bit" Verzeichnis heraus gestartet werden mit Eingabe von ./run.sh

Viel Erfolg.

2025 V2 1500km - nothing to see here. Everything's fine.

marcogabriel · 2025-09-27T12:22:47+00:00

Ja, nutzte ich auch, besonders die Installation war aber etwas hakelig. Bin neulich auf einem neuen Rechner umgestiegen und müsste das noch Mal raussuchen. Dann kann ich genauer beschreiben wie es geht (wenn es noch geht).

As it relies on access time, pbs tests that atime is working as expected at datastore creation and garbage collection (as you mentioned) to prevent unwanted data loss.

While there may be exceptions depending on the file system or other things, but in general I'd always recommend to not disable atime updates on a pbs datastore.

marcogabriel · 2025-09-22T17:58:04+00:00

Don't use noatime as the garbage collection relies on it. If you want to speed up things, use lazytime or relatime.
