CyberPowerのUPSを導入するよ
おうちで24時間稼働しているサーバを停電、雷から守るため
CP750PFCLCD JPを購入しました。
構成
UPSが停電を検知してバッテリーに切り替え
↓
Proxmoxに常駐しているPowerPanelが、バッテリー残量が一定の基準に低下したことを検知
↓
Raspberry PiにshutdownコマンドをSSHで送り、その後にProxmox自身もシャットダウン
🛠 準備をしよう
Powerpanelのインストール
ProxmoxのホストOSにPowerPanel for Linux 64bit (deb)をダウンロードします。
下記のコマンドでインストールします。
sudo apt install ./CyberPower_PPL_Linux+64bit+(deb)_vバージョン.deb
下記のコマンドでステータスを表示します。
sudo pwrstat -status

# The pwrstatd accepts four types of device node which includes the 'ttyS',
# 'ttyUSB', 'hiddev', and 'libusb' for communication with UPS. The pwrstatd
# defaults to enumerate all acceptable device nodes and pick up to use an
# available device node automatically. But this may cause a disturbance to the
# device node which is occupied by other software. Therefore, you can restrict
# this enumerate behave by using allowed-device-nodes option. You can assign
# the single device node path or multiple device node paths divided by a
# semicolon at this option. All groups of 'ttyS', 'ttyUSB', 'hiddev', or
# 'libusb' device node are enumerated without a suffix number assignment.
# Note, the 'libusb' does not support suffix number only.
#
# For example: restrict to use ttyS1, ttyS2 and hiddev1 device nodes at /dev
# path only.
# allowed-device-nodes = /dev/ttyS1;/dev/ttyS2;/dev/hiddev1
#
# For example: restrict to use ttyS and ttyUSB two groups of device node at
# /dev,/dev/usb, and /dev/usb/hid paths(includes ttyS0 to ttySN and ttyUSB0 to
# ttyUSBN, N is number).
# allowed-device-nodes = ttyS;ttyUSB
#
# For example: restrict to use hiddev group of device node at /dev,/dev/usb,
# and /dev/usb/hid paths(includes hiddev0 to hiddevN, N is number).
# allowed-device-nodes = hiddev

# For example: restrict to use libusb device.

停電を検知すると/etc/shutdown.shを実行してシステムをシャットダウンするようです。
スクリプトの冒頭にラズパイへのコマンドを追記します。
/etc/shutdown.sh
#!/bin/sh
+ ssh user@host 'sudo shutdown -h now' # ラズパイ
shutdown -h now
これでラズパイをシャットダウンさせてからProxmox自身もシャットダウンすることができます。
