Proxmox 9 was released, based on Debian 13 (Trixie), with some interesting new features.

For beginners here: do not run apt upgrade!! Read the documentation on how to upgrade properly.
It’s always good to read the docs, but I often skip them myself :)
They have this nifty tool called
pve8to9
that you could run before upgrading, to check if everything is healthy.I have a 3 node cluster, so I usually migrate my VMs to a different node and do my maintenance then, with minimal risks.
Yay, it only took 2 hours and the help of an llm since the upgrade corrupted my lvm metadata! Little bit of post cleanup and verifying everything works. Now I can go to sleep (it’s 5am).
Wasn’t that bad, but not exactly relaxing. And when my VMs threw a useless error (‘can’t start need manual fix’) I might have slightly panicked…
Not something that sounds production ready lol
Started a system upgrade at 3am…you ok?
I’m always up late (it’s 5:19a), though a good bit more than usual lately. But I did the upgrade because I was anxious, had nothing to do, and there were no users utilizing the machine.
ZFS now supports adding new devices to existing RAIDZ pools with minimal downtime.
Yes!!
Edit2: the following is no longer true, so ignore it.
Why do you want this? There are very few valid use cases for it.
Edit: this is a serious question. Adding a member to a vdev does not automatically move any of the parity or data distribution off the old vdev. You’ll not only have old data distributed on old vdev layout until you copy it back, but you’ll also now have a mix of io requests for old and new vdev layout, which will kill performance.
Not to mention that the metadata is now stored for new layout, which means reads from the old layout will cause rw on both layouts. It’s not actually something anyone should want, unless they are really, really stuck for expansion.
And we’re talking about a hypervisor here, so performance is likely a factor.
Jim Salter did a couple writeups on this.
As a person who just installed proxmox for the first time a couple of weeks ago, does this allow me to fix some of my mistakes and convert VMs to LXCs?
You could just start over if you dont have much invested into your current setup.
I’m in too deep. I’m trying this script. Fingers crossed
i don’t think so
Anyone got screenshots of the new mobile UI?
This is awesome, I am going to imediatly get a test cluster set up when I get to work. Snapshots with FC support was the only major thing (appart from Veeam support) holding us back from switching to Proxmox. The HA improvements also sound nice!
Testing in production? Brave move mate. :)
