Hi, I tried with a clear cache and the output is the same. The output section of your command that has to do with the mons, is this: "mon" : { "px1@px1" : { "direxists" : 1, "service" : 1 }, "px1@px1.xxx.com" : { "addr" : "10.11.20.129:6789/0"...

Hi all, I upgraded my cluster from v5 to v6 and now I want to upgrade ceph from luminus to nautilus. The problem is that the proxmox gui shows one cluster member two times, as you can see in the attached picture. ceph cluster heath is: ceph health HEALTH_OK root@px1:~# ceph status cluster...

Hi all, When I do upgrades to proxmox or other actions that jeopardise the clusters health (network stuff), I feel the need to disable the cluster/watchdog/fencing components of promox, in order to do the actions without the danger of a node rebooting because it was fenced. So, what is the...

Hi all, I did a "pvecm delnode hp4" and removed a node from the cluster. Everything looks fine. The only problem i got, is that i don't contol the removed node.... So if someone boots the node, it will come back online and as the documents state: "it is critical to power off the node before...

Hi all, I have a 3 node proxmox cluster with pve6, on HPE DL380gen10 hardware. I had just upgraded from pve 5 to pve6, so i was checking things. At some point I noticed that one node had wrong time and it was 10minutes behind. I added an ntp server and synced the time.... Immediately the server...

Hi all, I am on Proxmox 5.4.6 and I did a passthrough of an Intel x710 adapter to a VM. The adapter had a interface name on Proxmox (enp59s0f0) and after the VM started, the adapter was removed from Proxmox. I have two questions: - Now I have stopped the VM and I have removed the passthrough...

Hi all, I would like to convert an LVM based disk to VHD format. I have done it successfully by getting a backup (vma.lzo) and then decompressing it, extracting it and converting it (qemu-img convert). I woud like to do this in fewer steps. So, I have the following questions: - I though of...

Hi all, There is an option to select NUMA when you configure a VM's CPU. While I know the basic NUMA concepts, I don't really understand what this checkbox does. So, I have a few questions about it and an application that might benefit from enabling NUMA. Starting from the App, I have a VM that...

Hi Udo, Stoiko and all, I really appreciate your help. Udo's guide is really useful! I managed to resolve the problem, before Udo's reply, so unfortunately I didn't followed Udo's steps. Anyway, my problem device was (from my terminal history): root@hs4:~# dmsetup info...

Hi all, I tried to remove an FC VOL from proxmox and it didn;t go very well. The sequence was this: I had moved the disk of a VM to another VOL. After I did that, i tried to delete the unused disk, but proxmox didn't do it with the message: error with cfs lock 'storage-gix': lvremove...

Hi again, I would like to ask what is the technology behind storage migration. Is the "source" disk snapshoted before migration (LVM based disk) and if it is, does that mean that the VG that the source LV (VM disk) resides on, needs to have extra room for the sectors written after the...

Hi all, I have a 5.4-6 proxmox installation. I have connected an iscsi LUN by hand with multipathd. I have given the iscsi disk to LVM and the LVM to proxmox. I used it to transfer a few VMs on it (that was the purpose) and then I needed to disconnect the iscsi from proxmox and migrate the...

Hi, My cluster is running for over a year on gen10 and it is fine. I am on Proxmox 5.4-3, right now. Perhaps you have migrated your VMs, from much older Proxmox versions and there are virtual HW incompatibilities? My VMs, were created on the Gen10 cluster itself. Sp

Hi all, I am running Proxmox 5.4-6 on a 3 node cluster. I have a VM that consumes 15TB of storage, which is LVM based (it sits on FC storage). I would like to do a live migration of this disk, to a new storage (LVM storage, iscsi mounted on proxmox). Keep in mind that the VM is running and the...

Hi all, I tried to replace a host in my cluster. I removed the host from the cluster with the command "pvecm delnode hs2", reinstalled from scratch the new host with the same name (hs2) and then added the new host. The hosts was added succesfully, but when i try to migrate a VM, it says...

Hi, Black magic. It worked. Here is what i did: I added the line : drive 'if=pflash,unit=0,format=raw,readonly,file=/mnt/pve/useful/OVMF-20160813.fd' in /etc/pve/qemu-server/176.conf . Still complains about a ton of things, but i can get into a bootloader (see below). Then I do: loader > boot...

Hi all, I want to run a virtual Nexus 9K (cisco switch) on my Proxmox. There is an qcow2 image that I have used to create a VM in proxmox. The GNS3 project (network simulation) also provide a OVMF-20160813.fd file that I understand it is the UEFI BIOS that the VM must boot from...

Hi Dietmar, Thanx for the answer. Perhaps it would be a nice idea, to put a vibrant warning on the Proxmox GUI, that the cluster is in a state with no node redundancy at the moment. This kind of warning might break my false sense of redundancy because I had 3 active nodes in the cluster...

Hi all, Today, I rebooted one node and every node of cluster rebooted... Now, the details: I have a cluster of 4 nodes, where 1 is constantly down, because it has a hardware failure and we are waiting for spare parts. So, the cluster has 4 nodes, where 3 of them are alive. Now, I rebooted one...

Hi all, I have a proxmox cluster with a shared FC LUN (managed by LVM). The LUN is full and I would like to resize it. I have resized it on the storage but how do i do it in proxmox? Keep in mind that I'm running multipathd for redudancy and that I have a partition in the LUN. My lsblk looks...
