To make an cluster to single node

systemctl stop pve-cluster corosync
pmxcfs -l
rm -r /etc/corosync/*
rm /etc/pve/corosync.conf
killall pmxcfs
systemctl start pve-cluster

After having the gpu instance
sudo apt install nvidia-driver-535 nvidia-dkms-535
apt install nvidia-cuda-toolkit

sonarr, radarr,jellyfin ,jackett,flaresolver
jellyfin kod plugin make sure force http is disabled.
when you add items make sure you add all, movies ,tvshows and music in jellyfin plugin in kodi

jellyfin works fine so no need to install jellycon

Setup untagged VLAN network also works
https://www.belgai.de/blog/harvester/harvester_bridge_network/ add cloud init network data made it to work
Loadbalancer creation were failing. Goto settings in harvester and set vip pools.
If you add one more extra nic using the untagged network then creating an service object will lead to issue. The best is use the default managment network and create and service object to get an ip in the Subnet.
to ssh into vm using clusterIP we can do kubectl port-forward and ssh
Goto preferences and enable all the 4 settings including longhorn and rancher UI.
We can use Nodeport and forward traffic to host ip and nodeport in Route Virtual servers.
When we are port forwarding in router to ingress make sure ingress is configured with static NodePort. so that recreation ingress will always leads to fixed port.

Official firmware did not work at all.
Format the sd card and install https://github.com/smith3d/Marlin/releases/tag/2.0.x.14 - https://github.com/smith3d/Marlin/releases/download/2.0.x.14/Smith3D-E3V2-2.0.x.14-5x5-SlowProbe.bin
in Cura machine settings G29 ; worked
M420 S1 Z2 failed and M420 S1 worked in cura machine settings
Adjusted the z axis offset to -2.70 mm after doing the manual bed leveling. Z offset tuned using Z-offset Tool

Note

try 5x5 fast firmware from smith3d

Create Root CA (Done once)

Create Root Key

Attention: this is the key used to sign the certificate requests, anyone holding this can sign certificates on your behalf. So keep it in a safe place!

openssl genrsa -des3 -out rootCA.key 4096

If you want a non password protected key just remove the -des3 option
