mdlcd

LCDproc client for monitoring /proc/mdstat information on RAID arrays

Requires Python 3 (tested on 3.8 but should work on earlier versions), mdstat, and pylcddc. The included service file requires systemd.

Installing

For a system install, use pip install --system -r requirements.txt to install dependencies to the system, copy the script to /usr/local/bin, and copy the service to /etc/systemd/user. Make a symlink to it in /etc/systemd/system, then run systemd start mdlcd and systemd enable mdlcd. The service is configured to run as the user nobody, since no privileges are required.

Usage

Customization is possible through command arguments.

usage: mdlcd.py [-h] [--host LCDD_HOST] [-p LCDD_PORT] [-n POLLFREQ]
                [-a MDARRAYS] [--mdstat-file STATFILE] [--version]
