Cant install proxmox-kernel-7.0. But it was due to having no space left on /boot/efi (1GB). Using a apt autoremove helped. Just wanted to post it here, if anyone has the same situation.

Chapter 1: The Windows Server 2025 Storage Revolution and the PVE Dilemma
1. What Changed in Windows Server 2025?
In previous Windows Server versions (2016/2019/2022), the Failover Cluster validation wizard was more forgiving regarding shared...
Make sure never to hit anywhere near 100% on any resource otherwise you'll get increased latency and (micro) stutters.Probably best to ignore Hyperthreads and SMT (and only count real cores). Virtualization is usually trying to do the opposite of...
Thanks, that actually makes a lot of sense.
I was already trying to keep resource usage low, but I didn’t fully consider how quickly latency can spike once things get close to 100%. I’ll definitely aim to leave more headroom instead of pushing...
Hi everyone,
I’m currently setting up a Proxmox VE server and experimenting with hosting a lightweight rhythm/arcade style game server (similar to Geometry Dash Unlocked) for a small group of friends. The idea is to keep things smooth...
Copy + paste oversight, I guess?
Looking forward to the stable release and the (hopefully quick) push into the no-subscription repositories of it. :cool:
I ran a full set of tests today, and everything seems to be working fine.
No changes are apparent compared to before the update.
Performance improvement: None
Performance degradation: None
Increase in power consumption: None
Errors in the log...

Well done, thanks !
Three machines upgraded
CPUs: Ryzen 3600, Epyc Rome, Ryzen 5825U
Storage: ZFS across all three for root and data.
All smooth, no issues, everything operating as expected.
Kernel seems to be working well so far! (Uptime is less than 15 minutes so... will report back later...)

System: Dell PowerEdge R740XD
CPU: Intel Xeon Gold 6154

It occurred to me, now that you have vendor confirmation, you can build a test PVE (perhaps even with nested virtualization). Build a VM where you can generate traffic that will overwhelm the backup throughput and temporary location. This should...
Hi hassaan2090, thank you for your answer. I need study more about proxmox and qemu
Hi @bbgeek17, I agree with you. It is weird. The truth is, data has been lost from linux either from windows. I had a cacti on one linux server and all graphs...
I am a little confused about what data was lost - actual data inside VM, ie files/databases/updates, or monitoring stats from external service?
You should probably invest some time to understand how this critical process works and how it affects...
it sounds like you have a wrong ZFS module version installed? PVE doesn't use DKMS, and the version from your screenshot is not the version included in our recent kernels for PVE 9.x:
$ modinfo /usr/lib/modules/6.17.13-7-pve/zfs/zfs.ko | head...
The GUI for browsing files in PBS (for host backups) and in VE (for VMs) is nice, but sometimes you just want a shell.
proxmox-backup-client mount provides one, but that can be a pain to get working, especially when it's a LVM.
I wrote a tool...
@fabian Thanks!
Root cause was an old pinned kernel that I did not unpin before or after 8->9 upgrade.
Unpinning kernel and apt autoremove to nuke it permanently fixed the issue.
