Hi all, i have a proxmox cluster that utilizes shared luns (LVM) from an IBM 9500 flashsystem. The storage is attached to the hosts via FC16 for main use and via 100G for iscsi/NVMEoverTCP ethernet connections. The storage can supposely reach 1M+ iops. I was doing various tests the other day...

Hi all, I have a proxmox test setup. Each server has local storage. I am trying to migrate a VM from one node to another and it gives out the error: ERROR: migration aborted (duration 00:00:00): target node is too old (manager <= 7.2-13) and doesn't support new cloudinit section both nodes...

Hi all, I am once again in the dire situation where one proxmox node has problems with one multipathed iscsi device and it stopped responding to lvm commands which are stuck forever. I have tried many things to restore the iscsi device but I haven't managed to do it. The question is if there...

Hi all, I have a setup of 3 proxmox servers (7.3.6) running Ceph 16.2.9. I have 21 SSD OSDs, 12*1.75TB,9*0.83TB. On these OSDs I have one pool with replication 1 (one copy). I have set the pg_autoscale_mode to 'on' and the resulting PGs of the pool are 32. My problem is that the OSDs are very...

HI all, I have a dozen MD3800i 100TB storage arrays that I can reach over 10G iscsi. I would like to create ceph OSDs on these 100TB iscsi disks in order get the best of Ceph's redundancy (replication etc) for backup purposes. When I try to create the OSD, it fails: #pveceph osd create...

Hi all, I have a VM that runs a passthroughed ethernet x710 adapter with dpdk (danos). Since dpdk does polling, the CPU is occupied 100% all the time. So, i would like to pin specific cores to this VM (in proxmox), in order to disallow the host task scheduler to change the association of the...

Hi all, I would like to upgrade my cluster from 6 to 7 and at the same time I would like to upgrade the hardware (replace the servers with new ones). Now, I have 3 nodes with pve6. I am thinking of installing the 3 new servers with pve7, adding them to the cluster and then removing the old...

Hi all, We have recently upgraded proxmox from v6 to v7. I noticed some warnings on the Updates/repositories page and I have a few questions. - I don't have a subscription but i have the no-subsctiption repo enabled. I get a warning that the no-sub repo is not production ready. - If i disable...

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 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 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 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 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...
