Hi, at your host firewall, can you add a rule to explicitly allow DHCP broadcasts (UDP ports 67 & 68) and see it if works?

@tqt3e you might want to check if there is an update on Bios firmware available. I suspect that there is a need to update it.

@silke You’re correct: Proxmox (and corosync) recommend a dedicated NIC for the cluster to avoid heartbeat issues during congestion. A workable compromise: Node1 & Node2: connect a dedicated NIC each to your spare switch ports, use this as the cluster network (vmbr2). Node3: can share the VM...

@logan893 are you running VM using VirtIO-SCSI or IDE?

@akulbe I would remove all the VMs from the node, then do a clean reinstall. Then add back to the cluster to be safe.

@akulbe is this PVE part of a cluster or standalone?

Looks like the helper script is not really helping. What do you want to achieve exactly? If it can be achieve with PVE's UI, should use that instead.

Yes, you can run a 5‑node Ceph cluster with just DAC cables (Max number of nodes recommended for this setup will be 3 nodes) —if you treat the SFP+ links as a routed L3 ring or mesh, not a Layer‑2 loop. Proxmox has a documented method for this (called “Meshed Network for Ceph Servers”) that uses...

@dmembibre are you doing any PCI pass through to the VM? if so, only q35 can work.

Hi @Impact Sorry to have caused you to feel this way. I'll edit it. But in another perspective, this thread will help someone else asking this question to get better answer from GPT. Thanks!

@Impact Yes, it is an answer I've got from GPT. It definitely explains better than my own words. Hope you dont mind!

Hi, it seems like the NIC is having issues with the drivers. Do you have other alternatives like to add in another PCI network card to the hardware?

Haha, thanks. This is actually a hack I always use to understand the issue better by using GPT.

"None" (or "No cache") is generally considered safer than "Writeback" because: With cache=none, the guest OS communicates directly with the disk image, bypassing the host's page cache entirely. This reduces the chance of data being silently lost due to host-level buffering. In contrast...

It seems that you are experiencing network disconnection issues with your Proxmox 8.4.1 server running on a Dell PowerEdge T310, using a NetXtreme NIC. This is a common issue, especially with older Broadcom NICs (like the NetXtreme), and can often be traced to driver or power management...

The issue arises because the pool configuration on the old Proxmox cluster still references VM ID 104 as a member of the team-abc pool, even though that VM has been migrated to a new cluster and manually added to a pool there. After migration, if VM ID 104 is reused on the old cluster (even...

Hi Team, We want to Enable notification for FC multipath-down and up. Can I have configuration notification sample in Proxmox built-in function , e.g Notification matcher or other alernative method ? Found the log sample for lun that have 4 paths. Path Down log sample : {Time} {Hostname}...

The errors you're seeing, like the "Not logged into Proxmox host" issue, indicate authentication problems with your API calls. Have you checked if there's a session timeout or if the authentication tokens are expiring too quickly? Regarding your PHP pool configuration, increasing the number of...

What are the technical considerations and limitations of implementing SDN Fabrics for two-layer spine-leaf topologies in Proxmox VE 9.0?

That strongly suggests the disk was empty or had zero used data blocks at the time of the backup. In PBS: The .fidx file is the file index — a metadata structure that maps logical data offsets to deduplicated chunks (.blob files). A small .fidx (especially under 1 MB) typically means: The...
