kernel panic

Does anyone know what could cause this host crash: We have a linux guest VM running multi-day simulations. The guest reported the following: Heaps of space in zpool: My current guess is that an online resize of sdb disk image earlier in the day looked good but at the point the additional...

Hi guys, I've recently incorporated a second host into my environment and have been testing the live migration process. Surprisingly, it doesn't seem to work as expected. About 75% of the time, I've had to forcefully reboot the VM after migration due to crashes. I noticed a few posts about...

During backups to PBS the hypervisor will do a hard crash, it is not consistent at which point it does it. Sometimes a backup succeeds, and sometimes it will not. But after a few backups 1 will fail and fully crash the hypervisor. Does anyone have any idea where I can start at debugging this...

After updating the kernel along with other packages using "full-upgrade" to 6.5.13-1-pve I'm getting a kernel panic. How can I revert the upgrade?

Hi, I have a VM host with an ASRock Rack B550D4-4L mainboard with AMD Ryzen 7 PRO 5750G (with Radeon Graphics) CPU running a current PVE 8.1 with Kernel 6.5. # pveversion pve-manager/8.1.4/ec5affc9e41f1d79 (running kernel: 6.5.13-1-pve) The system runs very stable overall, but it only boots...

Hi all, since October 10th, my Proxmox server is randomly crashing with a kernel panic about once a day. Initially I was looking for hardware issues since I thought I had not done any updates prior to the first crash. However, I recently realized I had apparently forgot that, according to...

I have a general purpose, single-node server, which randomly ends up frozen under heavy load, when using kernel 6.2, usually when full backups are running. Woke up to below message this morning. This server was originally installed with proxmox 7.x, and operated flawlessly. Later upgraded to...

I run a 3-node PVE with CEPH. I migrated all VMs away from node 3, upgraded to the latest CEPH (Quincy) and then started the PVE 7 to 8 upgrade on node 3. After rebooting node 3 (now PVE 8), everything seemed to work well. So I migrated two VMs, one each from node 1 (still on PVE 7) and node 2...

Hello all, I am running a Proxmox server on version 7-1.2, few days ago i have experienced a power outage which causes system to fail at boot. When i connect a monitor to display, i saw that ZFS triggers kernel panic and system boot stucks. After that i have booted into recovery kernel, and...

I'm recently new to learning Proxmox and followed a couple YouTube guides to get a Plex (+arr) VM and an Open Media Vault VM up and running. I'm passing a ZFS into OMV, sharing a CIFS, then accessing that share in the Plex VM. My specs are Ryzen 5 3600, Asus ROG STRIX B450-F Gaming mobo...

Hi folks, I've got a persistent issue on my new Proxmox instance - getting a kernel panic everytime when trying to test ZFS filesystem (not zvol) with recordsize 1M, 512K affected as well. Here is test case which I've used to reproduce - it worked in 100% runs and I even was able to reproduce it...

Hi New using Proxmox, I have been trying to run OPNsense in a VM, already tried both available bios and machine configuration but the BSD kernel always enters in panic mode. The closest I have gotten to finding the cause of the problem is this post in the lxc forum. But I have not been able to...

Hello I've experienced this VM crash on a stock pve-manager/7.3-3/c3928077 (running kernel: 5.15.74-1-pve) [EDIT] there's a more explicit log message in the 2nd crash, see my second message below The VM worked well for 24h before the crash. The machine is a Celeron MiniPC that I've reinstalled...

Hello everyone, for a week now I have been trying to solve a problem on a server running proxmox 7.3 ! On December 6th, I found my server completely crashed in Kernel panic, that day I only managed to take one screenshot in IMPI. Since then, the server rebooted once every 24 hours more or less...

I have a very specific and strange problem and ita kinda urgent to solve it in a timely manner. Yesterday I encountered a kernel panic on my proxmox server looking at server management logs apparently there was a power outage and ups was out of service for maintenance booting to the default...

Hi, I experienced yesterday a peculiar problem while adding a storage. We have a file server on which i created a SMB share. For our PBS, i created a vmdisk of 10TB on that SMB share. when i added it the process timed out. What is weird is that on the file server, i saw the object created and...

Hi everyone, I just installed PVE on one of my computer. I've build a Windows 8.1 vm following this guide: https://pve.proxmox.com/wiki/Windows_8_guest_best_practices and now after ~10 min my PVE server crash ( sorry it's actually a picture of the screen :D ) How can I debug this ? Thanks.

Hello, First sorry if writing in wrong section. I'm a very happy user of PVE and PBS and I love them! This because in the last ca. 2 months, my PBS install is going in kernel panic randomly... I've already checked much logs as i can and i can't find nothing usefull... I'm keeping updated my...

Hello, I hope someone can help me, I'm in panic because of kernel panic. Because of bad weather the FI turned off and now my server shows kernel panic, but I don't think is because of the FI. I also did a lifecycle check and it didn't show anything of concern. One hour before I updated...
