## Setup

- [Download](https://www.proxmox.com/en/downloads/category/iso-images-pve)
- [Setup and official Information](https://www.proxmox.com/en/proxmox-ve/get-started)
- [System Administration](https://pve.proxmox.com/pve-docs/chapter-sysadmin.html)

## Quorum and qdevice

Required if cluster with two nodes

``` bash
#check quorum status
pvecm status

# output example:
# Votequorum information
# ----------------------
# Expected votes:   2
# Highest expected: 2
# Total votes:      2
# Quorum:           2  


# install on all promox servers
apt update && apt install corosync-qdevice

# install on qdevice
# tested on a raspberry Pi 4

apt update
apt install corosync-qnetd 
apt install corosync-qdevice

# execute on one of proxmox servers
# change <QDEVICE_IP> with qdevice ip address
pvecm qdevice setup  <QDEVICE_IP> -f

#check quorum status again
pvecm status

# output example:
# Votequorum information
# ----------------------
# Expected votes:   3
# Highest expected: 3
# Total votes:      3
# Quorum:           2  

```

### Power Management

```bash
#disable
systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target
#enable
systemctl unmask sleep.target suspend.target hibernate.target hybrid-sleep.target

#check current scaling
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
#change to power save echo "powersave" | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

# powertop
powertop --auto-tune

#reboot #add to crontab 
@reboot powertop --auto-tune >/dev/null 2>&1
```
