yes, this seems obvious, but the problem is that it is possible to add cephfs as import storage ...

don't know, if it was mentioned somewhere, but ova import not working from cephfs tried on different clusters

It is still ok. Some very old VM's like Debian 4, 5, 6... Etc. And similar Ubuntu (Yes we have to use them) have randomly problems (with IO?) and freeze with some kernel panic... Sometimes . Not often.... But it is ok!

A rack of Proxmox servers on 6.8.8-2-pve kernel and so far no problem.

A rack of Proxmox servers on 6.8.8-2-pve kernel and so far no problem.

I will try to restart the guests on the server with 6.8 kernel

latest kernel Linux 6.8.8-2-pve seems to be OK one experimental server with this kernel is running for a week and did not freeze so i will upgrade the rest of them....

No freezes. 6.5 is OK And I didn't have time formmore experiments yet...

Maybe you have to restart all the VMs? (did a live migrate...)

get the NIC firmware update from Broadcom

https://forum.proxmox.com/threads/kernel-6-8-4-2-causes-random-server-freezing.146327 do you have Ceph and NVMe drives? Another thread: https://forum.proxmox.com/threads/random-6-8-4-2-pve-kernel-crashes.145760

Hi @Der Harry , I have started a similar thread https://forum.proxmox.com/threads/kernel-6-8-4-2-causes-random-server-freezing.146327 My 12 servers are "freezing", no logs, no segfault, no memory leak, no amdgpu, no iommu issue, etc. Yes we have Ceph and some NVMe drives for Ceph OSD. This is...

This happens once in ten years... I've had now some very hot moments at a large scientific organization where I run a entire rack of Proxmox servers and a Ceph cluster. Even the basic infrastructure was randomly down (Firewalls, DNS, DHCP ...). But it's OK. Sh1t happens. That's life! The...

Please help identify the common factors that cause this problem. I can confirm, that I had exact the same issue as described by @Tim-AU and @Lephisto Still looking for the code different or added in kernel 6.8 causing this issue. * I'm using in the VM CPU host, is this the same in your case? *...

Asrock and Asus are server vendors And we have a good relation with them. And this Is not the case of RX570. As I wrote in my previous post, I'm aware of three different situations of 6.8 freezing - non of them applies to a epyc (non GPU) server. The RX570 relates to the Destroy DC context...

solved! it is definitely a kernel 6.8 bug i need to know which kernel patch/commit is causing this regression i'm looking in to ubuntu kernel and are the any proxmox specific patches? i will share this kernel problem with asrock and asus vendor

we need to know, what changed in kernel 6.8 and when it would be save, to go upstream again are the any proxmox specific kernel patches? tried kernel 6.8 without success: amd_iommu=off iommu=off default - no parameters and with ceph optimatizations amd_iommu=on iommu=pt pcie_aspm=off with...

after many attempts replacing PSU, CPU, RAM etc... trying different kernel parameters etc... checking ipmi and system for any error and logs checking all power cables and upgrading UPS updating BIOS, Firmware and BCM/IPMI BIOS configuring different options installing a new version of...

This thread is dedicated to the issue where the server just freezes. If the kernel gives error messages when the server crashes there is a thread https://forum.proxmox.com/threads/random-6-8-4-2-pve-kernel-crashes.145760 and not AMD GPU related as in...

Solved there is no bonding involved just the kernel (version) + bnxt_re module + Broadcom firmware + initializing RDMA RoCE I had the same problem. In my rack there are in total 25 pieces of Broadcom BCM57504 4x25G SFP28 PCIe network cards. Most of them do not have this problem, but some of...
