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
pve8to9that 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.
Not sure I want to check how far behind I am. How rough are these upgrades? I’ve got most things under Terraform and Ansible but am still procrastinating under the fear of losing a weekend regiggling things.
I just did three nodes this evening from 8.4.1 to 9, no issues other than a bit of farting around with my sources.list files.
Not noticing anything significant, but I haven’t tried the mobile interface yet.
I’d also like to know.
I built a new machine seceral months back with PVE and got the hang of it but it’s been “set it and forget it” since then due to everything running smoothly. Now I don’t remember half the things I learned and don’t want to get in over my head running into issues during a major upgrade. I definitely do want the ability to expand my ZFS pool so I will need to bite the bullet eventually.
It will vary but for me it was smooth
Previous 3 major release upgrades I’ve done were smooth, ymmv
I just did one of my two nodes. Easy upgrade, looks good so far.
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
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. :)
