Whats the output of ceph osd df tree and ceph health detail? Also ceph pg dump_stuck would be useful.

Cool that it worked! Do rename the RBD image though to reflect the new VMID in the name! Otherwise this could have unintended side effects as Proxmox VE uses the name to decide to which guest a disk image belongs to! Worst case, you delete the container and enable the "remove unreferenced disks"...

check your storage config and which content types are set. Those decide which storages are shown, depending on the use-case.

puh, overall, I would consider if switching everything over to a VM might not be the better option. Because then moving a disk image between any storage while the VM is running is no problem at all. LXC containers cannot be live migrated to other nodes and need to be shut down if you do a move...

What I do in some personal infra is the following: 2x PVE nodes with local ZFS storage (same name) 1x PBS + PVE side by side bare metal. The 2x PVE nodes are clustered. To be able to use HA I make sure that the VMs all have the Replication enabled. For Mailservers and other VMs where any data...

Memory accounting gets complicated very quickly once you peek a bit behind the curtains. First of, a VM doesn't necessarily use all the memory right after boot. Linux VMs that don't need most of their memory for example. With the new line in the memory graph, you can see how it behaves over...

Das ist bei alten Industrieanlagen, die viele hunderttausende bis millionen €kosten,n mitunter nicht so einfach ;) Neben dem Hinweis von @Falk R. bez. Treibern, die virtuelle HW so alt wie möglich für den Anfang: Machine type: i440 Disk als IDE, maximal SATA Falls der Rechner tatsächlich eine...

Ich vermute, mit den bisschen infos die ich habe, dass da noch ein Check des LVMs oder Dateisystem am laufen war. Der letzte kleinere Screenshot sieht zumindest sehr danach aus.

This is regarding the VM summary panel on Proxmox VE. In your screenshots you have "Memory Usage" with the line chart and one line below that is the "Host memory usage". Those values are the same in both screenshots → Proxmox VE did not get any infos from the guest itself and therefore shows how...

Sieh okay aus. Wenn du kein Ceph verwendest, ob jetzt als HCI Server oder um den Host zu einem externen Ceph Cluster zu verbinden, brauchst du die Ceph Repositories auch nicht unbedingt. Ansonsten einfach noch das letzte Ceph no-subscription Repo auch dazu geben (squid).

hmm, yeah, VLAN 1 is the default "no vlan configured" one. If you only have the vmbr0 and assign the VLAN tag in the VMs virtual NIC, any packet leaving the node should be tagged accordingly. Maybe run some tcpdump on vmbr0, or the underlying physical NIC enp0s316f6? To see if the packets from...

Ah okay. I understood that they want to see which VMs used to be on that node. In that case, I think checking task logs or syslogs for recovery tasks would work somewhat. Or you fetch the cluster/resources every minute or two, and can then diff to see what happened?

What do you want to achieve? Some VMs that should be placed in VLAN 3? The host should not be placed in any VLAN? Then, on the port that you connect your PVE host to the switch, 3 should be a tagged VLAN. If your switch supports it, configure an IP for it in the same VLAN. Then you can use ping...

Also https://pve.proxmox.com/pve-docs/api-viewer/#/cluster/resources would be always a first check to see where resources are at the moment. One API call that the web UI is using all the time. It should also report back guests on a failed node. With the "type" parameter you can narrow down the...

The pools need to be called the same. So if the pool on the second node is empty, you could rename it: zpool export {pool} zpool import {pool} {new name of pool, same as on other node} Or destroy and recreate it under the same name. If there is already data on it on the second node, try to...

Die Default Enterprise repos gibts nur gegen eine Subscription. Du kannst diese Disablen und stattdessen über Add die jeweils passenden no-subscription Repos hinzufügen. Siehe https://pve.proxmox.com/pve-docs/chapter-sysadmin.html#_repositories_in_proxmox_ve für mehr Hintergründe.

The Proxmox Mail Gateway wiki page has a Getting Started page that also explains how you can set up unbound directly on it as a dedicated resolver: https://pmg.proxmox.com/wiki/index.php/Getting_started_with_Proxmox_Mail_Gateway

Did you run apt update after changing all the sources? Because then it should usually find a few hundred packages to update. It might need to run again. But yeah, in that case it should be fine. In the upgrade guide we don't call pve8to9 anymore, after changing the sources :)

Do you have the "ballooning device" enabled in the advanced memory options? if not, then there is no way to get the detailed guest view infos and you are in the same boat as with the *BSDs ;) See the above or...

I don't know exactly what the situation currently is and what could be possible or not. But can you please bring that up either in our shop or via office@proxmox.com? Those would be the best channels to discuss this :)
