gurubert replied to the thread Assistance with proxmox Ceph-reef or quincy install..For 4. you need OCFS2. It can be used by Proxmax as shared directory storage like NFS. With qcow2 for the VM images you get thin provisioning and snapshots. But this setup is not officially supported by the company that makes Proxmox. You have... -

Like.
That’s not how Ceph works. Each disk is its own bucket. A server has a bunch of buckets. If Ceph is set to 3 copies it will by default keep one copy of each data block on at least 3 different servers, in whatever bucket it wants. So a VM hard... -
gurubert replied to the thread Assistance with proxmox Ceph-reef or quincy install..With a SAN and LUNs presented to each Proxmox host you do not use Ceph as the SAN already has its internal replication (RAID). You can use LVM on top of the LUN as written in the Proxmox documentation. Or if you want to have something similar...

alternativer Vorschlag: warum gibt’s du deinen VMs nicht einfach einen host Namen in deinem DNS, dann musst du dir die IP nicht nachschauen

gurubert replied to the thread Assistance with proxmox Ceph-reef or quincy install..You have a LUN from a SAN presented to all Proxmox nodes via FC or iSCSI? This is something that cannot be used with Ceph. Ceph uses local disks and replicates over the network. With a LUN you can use LVM as storage for the VMs.

Ich arbeite seit 2006 mit VMware und 2008 mit Veeam. Ich sehe jetzt keine Feature was explizit Veeam Nutzer adressiert, also können wir mal Veeam aus den Gedanken streichen. Auch so sehe ich derzeit keinen echten Mehrwert, außer das ich mein...

gurubert reacted to Johannes S's post in the thread Interessantes Projekt für PBS: PBS-Plus with Like.
Naja, ich würde es ja interessanter finden, wenn die oder der Verantwortliche versuchen würde, sich mit den Proxmox Entwicklern zusammenzusetzen, damit die zusätzlichen Features direkt im PBS verfügbar sind. Das wäre auch deshalb sinnvoll, da...

gurubert replied to the thread Ceph HDD OSDs start at ~10% usage, 10% lower size.This is normal. Ceph adds the size of the RocksDB device to the total size of the OSD. But since the RocksDB device cannot store any data it is computed as completely used. This is why you see a 10% usage on your fresh OSD. BTW: 80GB RocksDB...

gurubert replied to the thread Proxmox CephFS Permission Denied.To create client keys for mounting CephFS use the command "ceph fs authorize". It will create the necessary capabilities for the key.

gurubert replied to the thread Adding a Second Public Network to Proxmox VE with Ceph Cluster.This will not work. The public network is called public for a reason: each client that wants to access the Ceph storage cluster needs to be able to talk to every node in each public network.

gurubert reacted to alexskysilk's post in the thread Ceph - feasible for Clustered MSSQL? with Like.
As @gurubert mentioned, your solution doesnt match your problem description. you dont need 3 servers for a mssql cluster. you need two. You dont even need a nas/san at all, you have multiple options included windows failover cluster and storage...

I would never start a serious business with three nodes. Ceph requires some more resources to be reliable and fast; I've written down some things I've noticed...

gurubert replied to the thread Ceph - feasible for Clustered MSSQL?.If you want to run MSSQL in a clustered setup use local storage for its nodes. There is no need to replicate on the storage level if the DB replicates its data on the application level.

gurubert reacted to groque's post in the thread Suggestions for vm/containers while performing ceph upgrade to squid with Like.
Hello, I recently went through a similar upgrade (Reef → Squid) on a Proxmox VE 8.x cluster, so here’s some guidance based on both the official Proxmox recommendations and my experience: Should I turn off VMs and containers on all nodes while...

gurubert replied to the thread Does Proxmox plan to support SCSI over FC?.You need to create OCFS2 on the shared LUN including an OCFS2 cluster on all nodes. Read the OCFS2 documentation for details. The OCFS2 filesystem is then mounted at the same mountpoint on all Proxmox nodes. In Proxmox you can then create a new...

gurubert replied to the thread Does Proxmox plan to support SCSI over FC?.We are running such a setup with OCFS2 on the shared LUNs and qcow2 images in the filesystem for several years now. It works but is unsupported by Proxmox.

Nein, es hatte Jemand die Konfiguration geändert, aber der Kollege wusste wohl nicht, dass man die Running Config auf die Startuo Config kopieren muss. Der Befehl write, den er wohl ausgeführt hatte, hat keine Funktion, aber auch keinen Fehler...

Ich könnte dir valide Szenarien schreiben, aber ist ja in deinen Augen eh alles Falsch. Wenn du deine Infrastruktur gern anders betreiben möchtest als alle anderen, dann tu das. Wenn dir das zu viel Arbeit ist für dich oder die Profis, welche die...

Wenn tatsächlich mal der K-Fall eintritt und alles Down ist, was startet man zuerst? Richtig, die Infrastruktur. Blöd wenn der Hypervisor auf einen DHCP Server angewiesen ist, der eventuell noch nicht läuft. Jeder der ein Notfallkonzept...
