Den Einsatz solcher Tools will ich auch nicht pauschal verdammen, aber mir gehen (sowohl bei Fragestellern als auch Antwortern) die Tendenz (nicht nur von dir) auf die Nerven alles durch die KI vorformulieren zu lassen. Sobald etwas zu... -
Hallo zusammen, erstmal danke @sgw, dass du das Thema so sachlich hältst — es geht hier um dein Storage-Problem, und dabei sollte es auch bleiben. Genau dafür ist das Forum da, und genau deswegen bin ich hier. Mir tut es ehrlich leid, dass sich...

UdoB replied to the thread OCFS2(unsupported): Frage zu Belegung.Vielleicht verwendet er intensiv solche Hilfsmittel und der Stil färbt ab?

To be fair haben @Bu66as Beiträge hier im Thread dem User ja schon weitergeholfen. Ich finde den Stil aber auch leicht enervierend, insbesondere wenn im Beitrag (nicht hier aber an anderer Stelle) einfach nur etwas, was ein anderer User schon...

UdoB replied to the thread [SOLVED] What are the best practices for using Windows as a Q-Device arbiter in a two-node PVE cluster?.I had tested latency half a year ago: https://forum.proxmox.com/threads/qdevice-deployment.173182/post-805735 From my experiment it seems that a hundred milliseconds are tolerable.

Like.
Regarding mdadm: https://pve.proxmox.com/wiki/Software_RAID#mdraid I agree with both gurubert and onslow that ssd is the prefered way to go for a PBS datastore but backup on hdd is still better than no backup. One possible workaround around the... -

UdoB reacted to JeanL's post in the thread [SOLVED] Proxmox VE - VM Disk Hot-Add Not Detected by Guest OS with Like.
Hi, Since your hard disk (ide1) is orange, it's not plugged, you need to stop/start the VM to take effect; and it's most likely due to the fact that you are using the "LSI" controller with IDE disk (if I remember correctly, hot plug was never...

Hallo @rothkraut, das automatische Zurückmigrieren nach einem Ausfall ist über HA-Gruppen mit Node-Prioritäten möglich. Beispiel-Setup: Gruppe "brandabschnitt-a": Node1 (Priorität 2), Node2 (Priorität 2), Node3 (Priorität 1), Node4 (Priorität...

UdoB replied to the thread [SOLVED] What are the best practices for using Windows as a Q-Device arbiter in a two-node PVE cluster?.No. My hint regarding a separate NIC was for installing a PVE cluster member. A pure QDev has much simpler requirements ;-)

UdoB reacted to Johannes S's post in the thread [SOLVED] What are the best practices for using Windows as a Q-Device arbiter in a two-node PVE cluster? with Like.
One obvious potential issue are the network requirements of corosync: So your Windowsserver would need to have a dedicated network card which is only used by your PVE VM for the cluster communication. In contrast the qdevice doesn't need it...

Hallo, ergänzend zu der Antwort von @UdoB sei der Vollständigkeit halber noch ergänzt, dass Rules ebenfalls eine strict Option bieten. Siehe hier. Intern werden bei einer Node Affinity Rule, die nicht strict ist, Nodes, die nicht Teil der Node...

UdoB replied to the thread Whole disk backup every time on stopped VM.Maybe. I know for Datasets there are other attributes (meta-data) to evaluate. This thread is about a VM/ZVOL. Yeah, sounds clever! Thanks for adding this. But nevertheless the source ZVOL needs to be read, completely. And that was the main...

UdoB reacted to IsThisThingOn's post in the thread Whole disk backup every time on stopped VM with Like.
Like others already said, by default it reads everything. The money quote line is this one: 107: 2026-02-28 21:00:07 INFO: scsi0: dirty-bitmap status: created new Since the VM is not running and/or you have the stop backup mode, it can't make...

UdoB replied to the thread [SOLVED] HA-Migration auf vorherige Node.Das sollte das normale Verhalten sein, sofern man eine "unrestricted group" - mit allen Nodes - definiert hat: https://pve.proxmox.com/pve-docs/chapter-ha-manager.html#ha_manager_groups "Resources on unrestricted groups may run on any cluster...

UdoB replied to the thread Whole disk backup every time on stopped VM.No! Just remove it from the backup then. There is the "Selection mode:" "all" - what I expect you to use until now. And there is "Exclude selected VMs". So you can have all VMs to be backuped, except the one (or multiple) you select in the...

UdoB reacted to gfngfn256's post in the thread [SOLVED] What are the best practices for using Windows as a Q-Device arbiter in a two-node PVE cluster? with Like.
I still think that a QDevice is the way to go. Setting up another PVE VM (in Windows) just for the sake of GUI-visibility seems to me completely unnecessary and wasteful. Add to that, the NW element inter-cluster is more complex & generally...
