We tried that too but on Tuesday... didn't work at all.
We downgraded the whole cluster and reboot the 15 nodes one by one, but we only downgraded like that : apt install pve-qemu-kvm=5.1.0-8 libproxmox-backup-qemu0=1.0.2-1
root@host001:~# dpkg -l | grep -E "pve-kernel-5.4...
We are facing the same behaviour on 15 nodes (~600 VM), pve-manager=6.3-4, on Intel CPUs and No Backups enabled.
Can someone confirm that the downgrade in 6.3-3 is effective and stable as @tincboy and @pawkor suggested ?
Many thanks Udo !!
Your comment is very useful.
I think about a MySQL Cluster instead, it will be better (maybe), as I could not change/add new hardware in this kind of solution.
BTW Sorry for the delay, I was on Easter holidays :D
I read a lot of questions and answers but I really didn't find a good advice for my architecture :) :
We have :
- CISCO LoadBalancer
- 2 Proxmox (in Cluster)
My question is :
- How many maximum OpenVZ VM (ONLY no KVM) , could we do on that kind of hardware below :
