Hi @LnxBil ,
thank you for your reply and sorry for my late response (life happenz).
To answer further, we already use KSM.
I guess the solution here would be to restrict max ZFS ARC < ( SUM(VM RAM) + 2GB for PM host).
after conversion of LXC to KVM which works, i have black screen / VNC console until I switch to tty1 with ctrl+alt+f1.
Any ideas how to fix this, so that KVM 16.04 ubuntu based will start at tty1?

I have had SWAP on the same host and was almost empty when OOM killer hit. (I use MDADM SW RAID for it, cause ZFS has problems holding SWAP.)
It;s sunday today, so I will continue...
I understand and always join an empty node to the cluster.
But now I want to create cluster from one server which already contains VMs and is in production.
Can the first node, the one you create cluster on, also contain VMs?
If not, then I have to install new node, create a cluster...
I guess I will have to fix the script so that it does not check all services.
Till now if a service was listed in PVE, it was supposed to be running. But not anymore, so I guess this has to be changed:
return unless @options[:mode] == 'services'
I monitor all services listed in PVE HTTP GUI under System:
After upgrade from 6 to 7 i got notifications about chrony not running. I installed chrony (replaced systemd-timesyncd) but now systemd-timesyncd failure is triggering monitoring system. As both can not run at the same time, I wonder...
