Trying my luck in asking my question in this forum. Have 3-nodes that are physically cabled (each node has 2 cables to each other node, total 6 six cables, no switch) as a full mesh network per https://pve.proxmox.com/wiki/Full_Mesh_Network_for_Ceph_Server#Introduction (4. Broadcast: Each...

Per https://pve.proxmox.com/wiki/Full_Mesh_Network_for_Ceph_Server#Broadcast_Setup, I have a 3-node full-mesh broadcast Proxmox cluster working with traditional Linux networking. I've migrated the nodes to Open VSwitch. The only non-LACP bond mode options are active-backup & balance-slb. Well...

Just updated to the latest firmware on 13th-gen Dells and did a factory reset. This is going to be a 5-node Ceph cluster which was previously running VMware. I've noticed that SR-IOV is enabled in the BIOS. I do know that under ESXi, it's highly recommended to turn off SR-IOV. Should it also...

Currently have a PBS 2.x bare-metal server backing up VMs on a PVE 7 servers. The plan is to clean install the PVE 7 servers to PVE 8. Can PVE 8 read PBS 2.x VM backups? If that is the case, then I can clean install PBS 3.x on the existing PBS 2.x bare-metal server.

Yeah, yeah, I know. EOL CPU. Ceph was working fine under Proxmox 7 using the same CPU. I did pve7to8 upgrade and a clean install of Proxmox 8. Both situations got the 'Caught signal (illegal instruction)' when attempting to start up a Ceph monitor. It's either pointing to a bad binary or...

Got some summer interns incoming and they will have access to a Proxmox cluster. Is there a Proxmox role to restrict VMs to a specific network? Obviously they will need access to the management network but VMs will be on a different network for Internet access. If no such option is...

After a 3-node test Ceph cluster refused to boot after a lengthy power outage, I reinstalled Proxmox. After creating the Ceph monitors on each host, ran 'ceph-volume lvm activate --all' on the existing OSDs which ran without errors. However, still no OSDs. I'm guessing the new Ceph monitors...

I have a standalone Dell R620 ZFS host with 10GbE networking. I get the full network IOPS when doing a wget of a file on the R620. However, when I run the same wget inside a VM, I do NOT get the same network IOPS. Maybe I get about 60-75% network IOPS. Anything on the host and/or VM settings...

Updated a Ceph cluster to PVE 7.2 without any issues. I've just noticed I'm using the wrong network/subnet for the Ceph public, private and Corosync networks. It seems my searching skills are failing me on how to re-IP Ceph & Corosync networks. Any URLs to research this issue? Thanks for...

I have the following network setup: 192.168.1.0/24 VLAN 10 pve1.host.local 192.168.1.11/24 pve2.host.local 192.168.1.12/24 pve3.host.local 192.168.1.13/24 192.168.2.0/24 VLAN 20 pbs.guest.local 192.168.2.254/24 Each VLAN is protected by a firewall. Per...

I forgot the command-line kung-fu to tell urllib3 to ignore the self-signed certs on the Proxmox hosts. I have the same error as this post https://learn.redhat.com/t5/Automation-Management-Ansible/Ansible-proxmox-kvm-module/td-p/3935 Anyone remember the command-line or environment variable to...

Anyone successfully used the Ansible module of proxmox_kvm to get a MAC address of a VM for a PXE install? Here is the task code: - name: Get Facts proxmox_kvm: api_user: "root@pam" api_password: test api_host: test node: test name: test validate_certs: no...
