Hi, first off - using DHCP with Proxmox VE (and physical servers in general, IMO) isn't really recommended. In any case - this is totally expected, as nic0 is attached to the vmbr0 bridge. In such network scenarios, the bridge should have the... -
gurubert replied to the thread OSD crash blockiert gaanzen Ceph Kluster.Sind die OSDs mit Version 19 erstellt worden? https://docs.clyso.com/docs/kb/known-bugs/squid/ Wobei in der Fehlerbeschreibung kein Hängen sondern ein Crash erwähnt wird.

If you don't want to use proxmox offline mirror then I'd suggest using a HTTP-Proxy. This way you can whitelist the URLs. Allowing CDN IPs is (depending on the CDN) not really the most secure solution anyways since IPs are reused by multiple...

gurubert replied to the thread CheckMK Fehler Proxmox Monitoring: PVEScheduler und Interface Speed.Beim Interface warnt Checkmk, weil sich die Geschwindigkeit seit dem ersten Service Discovery geändert hat. Ist das tatsächlich der Fall (von 10G auf 1G)? Oder ist das jetzt einfach anderes Interface an dem Index? Dann sollte besser der...

Du hast doch im CheckMK Forum gesagt bekommen, das es ein Kindprozess (PVE Sheduler) handelt kann und der Zähler zu klein im CheckMK ist. Siehe: https://forum.checkmk.com/t/proxmox-ntp-time-pveschedule-interface-speed/59729/4 Es wurde dort... -
gurubert reacted to aderumier's post in the thread Ceph flapping OSDs - OSDs only using public network not the cluster one with Like.
cluster network is for osd->osd replication. osd->monitor && osd->client is done on public network. They are differents hearbeats, osd hearbeat between osd (on clusternetwork) hearbeat from monitor-> osd (on public network)...

No idea what the consequences are but 10.1.1.0/16 isn't a network. For a proper network all host bits should be zero. Use 10.1.0.0/16.

gurubert reacted to fabian's post in the thread [SOLVED] Are there mitigations available for CVE-2026-53359 'Januscape' with Like.
yes, we are aware, and currently preparing fixed kernel packages. the only known mitigation at this time is disabling nested KVM.

gurubert reacted to Francois Baillargeon's post in the thread Shutting down the cluster with ceph with Like.
It is preferable to have two rings as a misconfigured switching equipment on a bond might make the link down or flap for no reason. Imagine a failing switch with one of two members of a bonded link dropping say, 50% of the traffic on a bonded...

Any advice on powering down two clusters ? I have a 6 node closure on 8.3.1 (Enterprise repo) with 50-65 VMs pre node. Storage is a separate 5 node Proxmox cluster with Ceph same 8.3.1 version - this cluster is not running nay VMs. We have to...

gurubert replied to the thread Ceph flapping OSDs - OSDs only using public network not the cluster one.OSDs need both networks (Ceph public_network and cluster_network) to function on all nodes to be able to properly work . If one of these two networks do not work the OSDs flap.

gurubert reacted to SteveITS's post in the thread Ceph flapping OSDs - OSDs only using public network not the cluster one with Like.
That’s what I was trying to say…AFAIK the cluster network is only for replication. The VMs talk to it on the public network so that needs to be working.

gurubert reacted to Johannes S's post in the thread Proximo - The Proxmox MCP/A2A you can hand the keys — VE + Backup Server + Mail Gateway + Datacenter Manager on one audited trust core with Like.
Why did you open a new thread and why didn't you link the old one with it's critism? I still think that handing the keys to a vibecoded ai agent is a bad idea...

gurubert replied to the thread Promiscuous Port in PVE Cluster.Is it configurable after you manually migrate the VM to node 2? What happens to the mirror port on node 1 after the migration?

Thanks for sharing. Please note that Proxmox is a registered trademark, so please don't use it as part of your own product/app/tool name. You can indicate that your work is for Proxmox VE by, e.g., using a wording that avoids suggesting that this...

gurubert replied to the thread latency on ceph ssd.Slow networking also adds latency.
-
see this old blog: https://www.sebastien-han.fr/blog/2014/10/10/ceph-how-to-test-if-your-ssd-is-suitable-as-a-journal-device/ The main reason is sync write, without plp, the ssd need to write directly to a full nand. for example, you need to...
-
It's just that these are SSD consumer drives without PLP. These are slow if you force them to write the data (sync writes). You'll find many threads about this on the forum. Maybe you could buy small enterprise SSDs with PLP and put the WAL+DB...

don't use consumer ssd with ceph or zfs. you need PLP to handle sync write
